Use of low level laser therapy (LLLT) devices for treating hair loss has been heavily debated for some time by reputable hair restoration physicians and patients on our hair loss forum. While some physicians reject its use entirely, others use laser hair treatment as a regular part of their practice. Additionally, some physicians believe that laser light therapy can assist with postoperative healing after hair transplant surgery.
Shortly after the first working laser was invented in 1964, a researcher from Semmelweis University of Budapest named Andre Mester developed a theory that exposure to cold laser light (similar to UV radiation emitted by the sun) may eventually lead to cancer. To test his theory, Mester shaved a group of mice and trapped some of them in a cage with constant cold laser light exposure leaving the other half unexposed as a control group. To his surprise, the light didn’t cause cancer in any of his animal subjects. Instead, mice that were exposed to the laser light therapy grew back their shaved fur much faster than the control group. Mester named his discovery photo-biostimulation. His theory was that somehow, the laser light had stimulated the hair cells into an accelerated state of hair growth.
Today, low level laser therapy is being used as a hair loss treatment. To treat baldness with laser light therapy, laser rays are directly applied to the scalp by a mechanical device so that red blood cells are stimulated. Lasers are said to work by converting ATP (Adenosine Triphosphate) to ADP (Adenosine Diphosphate), releasing energy and causing cellular metabolic changes. During this process, additional nutrients and oxygen are provided to the scalp assisting the normal chemical processes performed by those cells, increasing overall blood circulation. Lasers, when applied to the scalp and hair, have been said to improve overall hair quality, promote hair growth, and increase hair shaft diameter.
Laser treatment devices have a similar appearance to a hood hair dryer which is placed over top of your head. The low level laser toll will rotate allowing laser rays, usually red in color, to be discharged into your scalp. Hand held devices such as the Hairmax comb have also been developed and resemble a brush in appearance.
Promoting healthy hair growth however, is not the same as the regrowth of miniaturized hairs brought on by genetic female hair loss or male pattern baldness (MPB). So what clinical evidence exists, if any, that laser therapy is an effective treatment? Below we take a closer look at the available data including exclusive interviews of leading hair restoration physicians.
Physicians have long shared varying views on whether or not laser treatment is viable. While some well respected physicians reject its use entirely, some believe that LLLT can provide marginal benefit for men and women suffering from androgenic alopecia (genetic baldness). Additionally, some physicians believe that laser hair treatment can assist a hair transplant patient’s postoperative wound healing process and expedite hair growth.
Dr. Charles (one of our well respected members of the Coalition of Independent Hair Restoration Physicians) believes it may provide similar hair loss prevention benefit to Rogaine in the mid vertex area and crown. Benefits in the frontal area include an increase in overall hair quality rather than hair loss prevention.
Dr. Charles believes LLLT works better when combined with Propecia (finasteride) and Rogaine (minoxidil). Like Propecia and Rogaine, he believes low level laser therapy may help some patients more than others and works better in patients with only minimal thinning hair.
Dr. Charles believes in helping balding men and women develop and maintain realistic expectations and he doesn’t oversell its benefits. Because lasers are free from side effects, he always tells his patients that the biggest risk is the money. Dr. Charles believes more research on laser hair treatment is needed.;
Dr. Williams of the Coalition has been using laser hair treatment as a regular part of his practice for over 2 years and feels quite confident in its success in some patients. In his experience, LLLT promotes healthy hair growth and can increase hair shaft diameter of miniaturized hair affected by genetic female hair loss and male pattern baldness in some patients.
Dr. Williams offers 16 free laser therapy sessions to local males following hair transplant procedures and encourages his female transplant patients to undergo laser light therapy for one full year at a highly discounted rate. Dr. Williams usually notices faster transplanted hair regrowth and a quicker resolution of postoperative telogen effluvium or “shock loss”, if it occurs.
Because androgenic alopecia is a progressive condition, Dr. Williams encourages male patients to use Propecia while encouraging out of town females to use the Hairmax laser comb to help maintain their existing hair. Dr. Williams would like to see more formal studies defining the benefits of lasers as a hair loss treatment, but he is encouraged by his experience with it to date.
Dr. Alan Feller (also a member of the Coalition) is one doctor who remains skeptical. "Medical lasers work in only one way, and that is to deliver energy to a target. When it strikes the target the energy is absorbed and converted to heat. That's it". Dr. Feller believes that more compelling evidence is needed to promote low level laser therapy (LLLT) as a hair regrowth solution or to stop hair loss.
study presented at the last International Society of Hair Restoration Surgery (ISHRS) meeting in Las Vegas (2007) by Maria A Muricy, MD, confirms increase in hair shaft diameter, fullness, and overall quality with laser hair treatment alone. Additionally, some statistically significant evidence reveals that low level laser therapy when combined with 5% minoxidil (the active ingredient in FDA approved Rogaine) provided noticeable cosmetic benefits for women in particular. However, this study also showed that laser hair loss treatment alone produced no statistically significant new hair growth in both men and women.
Another important issue to consider is the significance and meaning of the FDA clearance (not approval) of the Hairmax laser comb. Though some have proposed the Hairmax laser comb was only approved for safety, apparently the FDA did require Lexington International (who funded the study) to provide it with a study on its efficacy (effectiveness) in treating baldness. But this study and its results have not been released to the public since Lexington International had the option of submitting the study to the FDA privately. The obvious question then is – why would Lexington hide their study from the public if it proved the efficacy of laser hair regrowth?
While the Hairmax laser comb device was found by the FDA to be safe based on its “substantial equivalence” to previously approved laser light therapy devices and thus “cleared” (not “approved”), it was unclear to what extend the FDA reviewed or cleared it based on its effectiveness in treating hair loss. To learn more about the FDA standards for “approving” food and drugs and for “clearing” medical devices visit www.fda.gov
It appears that much of the laser hair treatment industry is now promoting their devices as “FDA Approved for Hair Loss” as if they are on par with the two only FDA approved hair loss solutions Propecia (finasteride) and Rogaine (minoxidil). However, until laser hair treatment provides compelling public evidence of its effectiveness in treating hair loss, it is quite possible that the effectiveness of low level laser therapy may be oversold by some companies. We expect that time will tell.
Alopecia areata (sometimes referred to as“spot baldness”) is a medical condition that typically results in patchy hairloss or bald spots on the scalp, beard, arms and legs. Though the exact cause of alopecia areata is unknown, it is thought to be an autoimmune disorder causing the body’s immune system to attack its own hair follicles, resulting in hair loss.
Roughly 2% of the world’s population suffers from alopecia areata and approximately 5% of these have a family history of "alopecia", the medical term for hair loss.
Alopecia areata is normally diagnosed through the observation of symptoms. However, occasionally a scalp biopsy or blood tests may be performed.
There is no cure for alopecia areata and current treatments, while sometimes effective, offer limited success. Current treatments for alopecia areata include; steroid injections, topical corticosteroids (steroid hormonesnaturally produced in the adrenal cortex of vertebrates), topical immunotherapy, Rogaine(minoxidil) and ultraviolet light therapy.
Although permanent hair loss is a possibility, the course of the disease is unpredictable and varies from patient to patient. The good news is that, even without treatment and after many years,the hair follicles do remain viable and ready to resume normal hair production if and when they receive the appropriate signal. Hair regrowth may, and often does, occur in time.
Patients suffering from alopecia areata are rarely considered good candidates for hair transplant surgery because donor hair grafts harvested from the “safe” zone at the rear and sides of the scalp are still vulnerable to the effects of the body’s immune system once transplanted to the recipient sites. However, if the affected area is small, has remained unchanged for an extended period of time and if there is no sign of inflammation below the scalp, hair transplantation may be an option. This would require a thorough consultation with a skilled and experienced hair restoration surgeon and the patient would need to fully understand and accept the risks of such a procedure.
Depending upon the severity of the condition, hair loss concealers like Toppik, Nanogen and DermMatch may help disguise bald patches. In more severe cases, a hair replacement system or full wig may be necessary.
Aswith all forms of hair loss, patients suffering from alopecia areata may experience emotional and psychological trauma. It’s important to reach out to family and friends, join an alopecia support group and/or seek the services of a mental health professional if you are experiencing intense, prolonged and overwhelming psychological effects.
Hair loss is a universal condition, affecting all ages, races, genders and nationalities. It’s estimated that “androgenetic alopecia,” or male and female pattern baldness affects 35 million men and 21 million women in the United States alone. This section examines how race, age and gender affect hair loss.
In physiological terms, human beings are all composed of the same bones, muscles, and everything else down to the cellular level. But there are specific differences.
Hair, in all of its variations, is one area in which human beings display their differences. Hair follicles can widely vary in terms of color, length, shape, thickness, strength and various other factors.
There are many ethnic groups to consider. But we will focus on the special considerations of Asians, Blacks (of African descent) and Caucasians.
Asian people typically have very straight hair. Their scalps contain fewer hairs per square centimeter, they actually have a lower hair density than that of Caucasian hair follicles. But because the individual hair follicles of East Asians are thicker, this gives the look and impression of greater hair density.
For these reasons, hair restoration techniques for East Asians, much like other races, must be sensitive to a variety of anatomic and cultural differences. For instance, East Asian females often have an increased likelihood of developing “diffuse alopecia,” or hair that thins evenly over the entire head than Caucasian females.
Even though it’s not a definite requirement, it’s very helpful for Asian patients to seek out doctors with experience in Asian hair.
Another consideration for East Asians considering hair restoration surgery is the increased chance of developing keloid scars. A keloid is a thick, irregularly shaped and elevated scar with uncontrolled growth that results from excess fibrous skin tissue. East Asians typically have a greater likelihood of keloid development than Caucasians, but less than that of people of African descent. Therefore, before undergoing surgery, East Asians may want to consider being medically evaluated for keloids.
People of African descent usually possess naturally curly hair. This curly hair gives the visual impression of increased hair density for a given amount of hair, which is beneficial in hair restoration surgery.
The hair follicles beneath the skin of people of African decent also typically curve more than Caucasians. This can make harvesting the donor hairs, without severing or transecting the hair follicles beneath the scalp, more difficult. A hair restoration physician needs to be very aware of this difference and adjust to its requirements.
As in the case of East Asians, people of African descent possess some unique hair and skin characteristics. Some of these medical conditions are more common in black skin than in white skin. This may increase the risk for post-surgical complications.
Those of African descent have a higher chance of developing keloid scarring when injured. This in turn leads to a greater chance of noticeable donor scars. Keloids aren’t a widespread problem. But those with a history of them are carefully evaluated in regard to their existing scars. The evaluation usually involves a small "test procedure" to determine if there’s a normal healing rate.
Another issue is that of postoperative skin discoloration. With darker skin, there’s often a greater risk of both increased and decreased skin color after injury or surgery. These risks can be determined by the patient’s medical and family history.
Ingrown hairs are also a more common problem in darker skin. If a patient has a history of ingrown hairs or other minor skin infections, this may signal a higher risk for ingrown hairs post-hair restoration surgery. Again, this risk can be determined by a small test procedure.
Caucasians (white people) may have a wide range of hair and skin types. However, if someone has dense and or coarse hair, as well as skin color similar to their hair color, they will generally achieve the best results for a given amount of restored hair.

Viviscal's hair growth vitamin and dietary supplement taken twice daily promises to "reverse hair loss" and grow thicker hair in both men and women experiencing balding and thinning hair. Its primary activeingredient, AminoMar C™ Marine Complex, is said to be a proprietary blend of ingredients and proteins that "provides the essential nutrients needed to nourish thinning hair and promote existing hair growth".
The entire Viviscal product line includes an "all natural" dietary supplement, a shampoo and conditioner, and a scalp lotion. Viviscal is promoted as being 100% natural, drug-free, gluten-free and safe from harmful side effects. But can Viviscal deliver on its promises to reverse hair loss and grow new hair?
In 2011, Viviscal advertisement was banned in the United Kingdom by the Advertising Standard Authority (ASA) who deemed that its claims to maintain optimum hair health were unproven. The ASA concluded:
"Because the evidence sent did not show that the ingredients in Viviscal had been shown to have a positive effect on hair health, we concluded the claims that the product could 'nourish hair follicles' had not been substantiated' and ruled the advert cannot be broadcast until it is changed."
However, as with many similar products promising to grow hair, substantiating their hair growth claims may not be a simple task.
Viviscal’s manufacturer does reference a number of studies that seem to support their claims of growing thicker hair. For example, the results of "Scientific Pilot Study #1" on 40 hair loss suffering females with an average age of 35 concluded, "Viviscal was well received by test subjects and the analysis of hair counts showed a mean reduction in hair loss of 46% in only 10 weeks." Additional studies are cited on Viviscal’s website.
Recently, we learned that Dr. Glenn Charleshas publicly endorsed Viviscal. Dr. Charles has an outstanding reputation for performing state of the art hair transplant surgery and is a highly esteemed member of the Coalition of Independent Hair Restoration Physicians.When asked to comment on his public endorsement of Viviscal, Dr. Charles stated:
"I have never had any hair loss patients display any negative effects. I describe it to my patients as a natural supplement that can promote a healthier scalp and hair. It may also, in turn, slow down the hair loss process. I tell all my patients that there are no guarantees with this product. Although most patients believe that they did have improvement after using this product, I admit that some patients do not see any noticeable changes that either they or I can identify."
Other hair loss experts are not as optimistic regarding Viviscal’s hair growth potential. Coalition member Dr. Bill Rassmanof Los Angeles states:
"I am skeptical of the photographs (results) and the changes shown make me doubt what the Viviscal marketing department wants me to see. Viviscal reportedly contains ‘special marine extracts and a silica compound’ - and yet I’m to believe this will regrow hair? If these photos were real, the product would have taken over the market years ago."
It's also important to note that Viviscal does notmake any claims on their website that their products can reverse the effects of genetic hair loss. Instead, it simply states, "Viviscal works to reverse hair loss due to stress, poor nutrition, and many health related ailments".
So is Viviscal an effective hair loss treatment? More research may be needed before this question can be effectively answered.
While there may be no harm (potential side effects) in trying it, at an average cost of $600 per year there are certainly more affordable and proven treatments available. The only clinically proven and FDA approved medical hair loss treatments currently available are Rogaine (minoxidil) and Propecia (finasteride). While Rogaine may be used by both male and female patients, Propecia is safe and approved only for male hair loss sufferers. Always consult your physician before adding any treatment to your hair loss regimen.
Nettle root extract can be found in a number of popular hair loss treatments, such as Provillus and Procerin, and at your local health food store as a standalone product. Conjectured to effectively inhibit the production of DHT, below we examine whether or not nettles are as effective as Propecia (finasteride) in blocking DHT and stopping the progression of male or female pattern hair loss.
“Nettles” is the common name for Urtica Dioica, an herbal plant also known as the Stinging Nettle. This perennial herb is often eaten in many parts of the world and is often added to soups, salads or cooked as greens, though less frequently. Nettle leaves are long and pointy, but only the shoots and top of the plant are eaten. Nettle plants have dark green leaves and typically grow about 2 or 3 feet tall and its flowers are covered with tiny stinging hairs that contain an irritant. Allergic reactions are common if they come in contact with human skin.
Nettle root extract was found to partially block 2 enzymes by researchers such as R. Hartmann. The first is 5-alpha-reductase that when combined with testosterone, produces DHT (dihydrotestosterone). DHT is the hormone responsible for androgenic alopecia hair loss. The second enzyme is aromatase, which makes estrogen. Combining nettle root extract with another herbal agent pygeum has been found to inhibit these two enzymes more effectively than either one alon It was shown that nettle root extract had to be used at high dosages in order to effective whereas lower doses of pygeum worked well. Prostatonin, the combination product of nettles and pygeum have been used to treat BPH (benign prostatic hypertrophy).
Studies by researchers JJ Lichius and others have shown a reduction in prostate growth in mice when large doses of nettle extract were taken orally. Combining nettle root extracts with saw palmetto berries in BPH patients reduced the amount of testosterone and estrogen. Conversely, it has been conjectured that nettles can block testosterone from binding to the sex hormone globulin, a carrier protein that binds testosterone and limits its bioavailability in the body. As a result, nettles have been called an aphrodisiac since it may help maintain testosterone levels.
Other uses of Nettles include treatment for arthritis, asthma, kidney, urinary tract infections, and last but not least, baldness.
Nettle Root as a Hair Loss TreatmentLike many other herbal supplements with some clinical evidence suggesting efficacy in treating enlarged prostates (BPH), some have claimed that nettle root extract may stop hair loss and maybe even aid hair regrowth. Because Propecia (finasteride) works to stop the progression of male pattern baldness by inhibiting the production of DHT, it is conjectured that nettle root extract may be of similar benefit.
Nettle root is a popular ingredient taken orally in a couple big name hair loss products such as Provillus and Procerin. Some have also conjectured that applying nettle root extract topically to the scalp may also facilitate new hair growth. Because many topical irritant type products are used to treat alopecia areata hair loss, some suggest nettle root extract applied topically may be effective in treating it. Those who conjecture its efficacy to treat baldness recommend doses of 500mg or more daily.
Though some have declared that nettle root extract may be an effective hair loss treatment, no clinical controlled studies have been performed proving its efficacy for androgenic alopecia (genetic female hair loss and male pattern baldness) or alopecia areata.
Despite claims made that “all natural” herbal supplements are free from side effects, nettle root has its share of warnings. When topically applied, irritation of the scalp or an allergic reaction can occur. When taken orally, it can cause upset stomach, burning, difficulty with urination, bloating and edema. Nettle root extract should not be used in patients with heart or kidney problems, due to fluid retention properties.
Those who want to try nettle root extract as a hair loss treatment should proceed with caution and consult their doctor before using it.
As the field of medical hair restoration continues advancing and evolving, hair loss sufferers look toward new, cutting edge clinics and corporations for faster, more effective, and less invasive hair loss treatments. In various but not all cases, the breakthroughs achieved through oral medications and topical solutions (seen in proven hair loss treatments like Rogaine (minoxidil) and Propecia (finasteride) are fantastic. Thus, hair restoration entities continue striving to create the next advancement and bring the world closer to a “hair loss cure.” However, for each hair restoration treatment that’s proven safe, effective, and efficient, it seems as if a dozen others are rejected for being unproven, inefficient, or unsafe.
For this reason, it’s always advantageous to thoroughly research the newest hair loss solutions and determine whether they are safe and effective, or if they fail to live up to the high expectations set by the current gold standard treatments such as proven solutions Propecia and Rogaine. Below, we evaluate whether Spectral.DNC, a topical solution created by Divine Skin Laboratories (DS Laboratories) can help stop hair loss and regrow hair.
Spectral.DNC is a topical treatment formulated by DS Laboratories which claims its “the world’s most effective topical hair loss treatment.” But can Spectral.DNC live up to these lofty claims and offer a more effective solution, or will it suffer the fate of many therapies before it and fail to gain the approval of the hair restoration patient community?
According to DS Laboratories, Spectral.DNC is applied (as an atomized mist or liquid) to the balding scalp twice daily, once in the morning and once at night. Along with a series of vitamins and herbal supplements (herbal extracts, copper peptides, and a vitamin complex), the active ingredients in Spectral. DNC are 5% minoxidil, Aminexil (SP94), and Retinol. Since minoxidil is also the proven, active ingredient in topical Rogaine, Divine Skin utilizes a frequently asked questions feature on its website to explain how Spectral.DNC is different and more effective than minoxidil. According to Divine Skin, it’s the two other active ingredients – Aminexil and Retinol that make Spectral.DNC more effective than Rogaine.
Aminexil (or Aminexil SP94) is a compound currently featured as an active ingredient in a line of healthy hair shampoos by L’Oreal. Aminexil is allegedly helpful in the treatment of perifollicular fibrosis – a pre-mature aging of hair shafts caused by inflammation and an overproduction of collagen proteins. It’s worth noting that while some reputable sources have researched its connection to perifollicular fibrosis, it hasn’t been conclusively linked to hair loss (especially androgenic alopecia hair loss), nor is Aminexil proven to treat perifollicular fibrosis. Furthermore, Aminexil is not recognized or approved by the United States Food and Drug Administration (FDA) as a treatment for any type of hair loss.
DS Laboratories indirectly counters these statements by sharing the results of a “worldwide” study which demonstrated an 8% increase in hair growth and a 6% increase in hair shaft diameter in hair loss sufferers using Aminexil (compared to a placebo group). This study however, is not without its limitations. This study was conducted in 1994, only contained 130 participants, lasted for 42 days, and doesn’t appear to be published in any sort of peer reviewed publication. Because of this, it’s difficult to evaluate whether or not the addition of Aminexil as an improvement over simple 5% minoxidil. But what about the Retinol?
Retinol (and its derivatives) is a form of Vitamin A, often used in medical dermatology for maintaining healthy skin and treating specific types of acne. Allegedly, certain forms of Retinol act as hair restoration drugs (after periods of long term usage) by preventing hair loss hormones from binding to target receptors and killing healthy hair follicles. While evidence of these claims was difficult to find, many Retinol users claim that the drug is harsh on skin and utilizing it in the scalp would cause irritation and require small, likely ineffective dosages. Much like Aminexil, there’s no solid evidence to suggest that Retinol makes Spectral.DNC a more effective hair loss solution than Rogaine or other minoxidil related products. Interestingly enough, while copper peptidesare listed as in inactive ingredient, research supports that copper peptides may play a role in transforming thin vellus hairs into thicker terminal hairs, increasing follicular size, and regenerating healthy scalp skin. However, because copper peptides aren’t listed as an official “active ingredient” by DS Laboratories nor do we know its concentration, it’s difficult to gauge its efficacy within Spectral.DNC.
The only proven and FDA approved ingredient in Spectral.DNC is 5% minoxidil. While minoxidil is safe and efficient, it’s unclear what the additional ingredients in Spectral.DNC may actually accomplish. Furthermore, the cost of Spectral.DNC runs between $35.00 and $45.00 for a month supply, compared to around $ 25.00 for a three month supply of generic 5% minoxidil. According to DS Laboratories, the only known side effects revolve around minoxidil (which are no different than those associated with Rogaine). Although minoxidil is relatively safe and effective, it’s been used as a hair loss treatment for decades.
Those hair loss sufferers considering using Spectral.DNC as a treatment for thinning hair can feel confident knowing that they will, at the very least, obtain similar results to using minoxidil 5%. Until the other active ingredients are peer reviewed, whether or not Spectral.DNC is more effective than Rogaine 5% is mostly conjecture.
We believe that patients have a right to full disclosure and a complete understanding of exactly what hair restoration surgery involves.
This step by step presentation shows how today’s state of the art follicular unit hair transplant procedure is typically performed.
During surgery hair follicles from the back of the head that are genetically resistant to going bald will be removed and relocated (transplanted) to the balding areas.
Prior to surgery, the hair in donor area that will be surgically removed is trimmed.
Once the donor area has been prepared it is given local anesthesia.
The donor tissue containing the bald resistant hair follicles is then surgically removed.
The donor tissue containing the bald resistant hair follicles is then surgically removed.
When patient’s hair is combed over the donor area the sutures are not visible. These sutures are typically removed approximately ten days after surgery.
Surgical technicians then use microscopes to view the donor tissue in order to dissect and prepare follicular units hair grafts.
After being given local anesthesia, the balding recipient area is ready for surgery. No trimming or shaving of hair is needed in the top recipient area.
Tiny incisions are made in the recipient areas in irregular patterns that mimic nature. The follicular unit grafts will then be placed carefully into these tiny incisions.
Follicular unit grafts are gently placed into the recipient incisions.
Typically the smallest one and two hair grafts are placed in the very front of the hairline, with three and four hair grafts placed behind them.
Following surgery a patient will have hundreds of tiny incisions with short hair stubble showing from the new grafts.
The tiny graft incisions heal rapidly. The redness and scabbing in the recipient area normally clears up within about one week.
Our physician members perform a very refined hair transplant procedure called "Follicular Unit Hair Transplantation". Today there are two methods for doing this procedure. They differ only in the methods used to harvest and prepare the grafts.
