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.

Race and 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 Hair Loss Considerations

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.

African Hair Loss Considerations

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.

Caucasian Hair Considerations

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.

Causes and Treatments

Alopecia is the medical name for hair loss to the scalp or body.  While Androgenetic Alopecia (genetic hair loss) is the most common, there are many other forms of alopecia related hair loss worth discussing.  Each medically named alopecia comes with distinct symptoms, a unique cause and exclusive treatments. Below, we've compiled a list of and description for the most common types of alopecia related hair loss along with the available treatment options for each.

While the information on this website can be used as a guide, men and women who believe they are experiencing hair loss should always be properly diagnosed by a qualified hair restoration physician to determine its cause.

Diffuse Unpatterned Alopecia (DUPA)

Cicatricial alopecia (Scarring Alopecia)

Alopecia Universalis and Alopecia Totalis

What Is DUPA?

Diffuse Unpatterned Alopecia (DUPA) is a form of genetic hair loss characterized by diffuse thinning over the entire scalp. Unlike Diffuse Patterned Alopecia (DPA), DUPA lacks the stable permanent zone associated with other forms of alopecia.

Dr. O'tar Norwood defined DUPA in his 1975 seminole publication "Male Pattern Baldness: Classification and Incidence" as:

Diffuse, Unpatterened Alopecia (DUPA). In this type, there is a general decrease in the density of hair without any definite pattern, although it is usually more marked over the top and front. This type is common in women.

Identifying DUPA

Diffuse Unpatterned Alopecia patients have a similar pattern of hair loss to DPA patients but the balding tends to occur more rapidly. DUPA patients are also more likely to achieve the “horseshoe” pattern commonly associated with Norwood class VII baldness. However, unlike other forms of alopecia hair loss, the DUPA “horseshoe” takes on a thin and transparent appearance.

It is important that patients suffering from diffuse hair loss are properly diagnosed. While DPA patients are often good candidates for surgical hair restoration, DUPA patients typically make poor hair transplant patients due to the lack of a stable zone in which to harvest donor grafts.

Treatment for Diffuse Unpatterned Alopecia

Not a lot is known about the cause and treatment of DUPA. However, about half of males who suffer from this form of balding benefit from Propecia (finasteride). Unfortunately, DUPA is about 10 times more common in females for whom Propecia is not a treatment option.

Conclusion

Anyone suffering from diffuse hair loss should consult with a dermatologist or hair restoration physician for a proper diagnosis. This is especially true for balding men and women considering hair transplant surgery.

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.

Contained in Several Popular Hair Loss Treatments for Men

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.

Description

“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.

Use of Nettles

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 Treatment

Like 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. 

Possible Side Effects of Nettles

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 patients, we know that the physician you choose is the most critical decision in restoring your hair is the physician you choose. Hair restoration physicians' skills, experience, and talent vary widely, as do the end results, vary widely.

You must research and choose your physician wisely. After all, who you choose will determine how natural and complete, your new hair will be for the rest of your life. The surgeons selected and approved by our community have been scouted and vetted by the forum's highly esteemed senior valued contributors of the Hair Restoration Network. Our valued contributors have all spent years researching hair transplantation, and they have all had hair transplants. To ensure there is no conflict of interest, none of our valued contributors receive any compensation. They are volunteers who have shared their experiences and contributed for years to our community. Each surgeon has been approved based on their ethics, surgical techniques, results, and reviews. To support the costs of operating and promoting our community, the approved physician contributes a monthly fee to sponsor our community.

Their recommendation is continued as long as they continue to show evidence of excellent patient results and satisfaction. If a patient expresses concerns, physicians are expected to resolve their concerns. We ask that patients first contact a physician with any concerns so that they can resolve them before publicly posting.

Note - The hair restoration physicians recommended on this site are not a definitive list of all excellent hair transplant doctors. Nor do we warrant or guarantee the results of any of the physicians presented on this site. As always, we encourage you to do your due diligence in evaluating these and all hair loss physicians.

We offer the following suggestions for researching a hair restoration physician:

• Does the physician take a holistic approach to hair restoration? Your physician should help you evaluate all your options, surgical and non-surgical.
• Have they invested time and resources in large micro follicular unit hair transplantation sessions? Outstanding work requires a staff dedicated to and trained to use high-powered magnification to produce more than 2,000 carefully trimmed grafts per surgical session.
• Choose a hair restoration clinic that is patient-focused rather than commercially focused. Some clinics emphasize revenue, speed, and volume rather than dedicating the time and individual care needed to produce optimal results. These commercial operations typically rely on heavy advertising rather than satisfied patient or doctor referrals.
• Is hair restoration the primary focus of their practice? Outstanding results require a physician and staff to perform hair restoration surgery regularly. Doing hair restoration as a sideline and other cosmetic procedures may hinder their ability to do large sessions of highly refined follicular unit transplantation.
• How many patients has this physician produced excellent results for? Like any skill, experience over time is critical to acquiring the skill and judgment required to produce excellent results.
• Can the physician provide detailed patient before and after photographs? Do they also have patients who are willing to speak with you and meet with you in person?

What do their hair transplant patients think?

Ultimately, the most critical measure of a hair transplant surgeon's work is their patient's level of satisfaction.
