Over the past several years surgeons have used various techniques to perform follicular unit hair transplantation. One such technique is the Lateral Slit Technique, also known as Coronal or Perpendicular Grafting. This technique’s name is derived from the angle and direction in which the graft incisions are made.
While there are other techniques for performing densely packed and highly refined follicular unit transplantation, the lateral slit technique offers a high degree of control over the angle and direction in which the transplanted hairs will ultimately grow.
The lateral slit technique has been used both intuitively and systematically for years by hair restoration physicians. However, it has recently gained popularity as a systematic and precise way of performing follicular unit hair transplantation.
Many of our physician members use the Lateral Slit Technique exclusively or in combination with other techniques for creating graft incisions. The lateral slit technique enables a surgeon to create graft incisions at varying angles (ranging from 10 to 90 degrees to the scalp), including very acute angles that will make the transplanted hair grow out lying flatter to the scalp. The ability to create incisions at very acute angles is particularly useful in areas such as the front temples and sides where the hair normally grows out lying flat on the scalp.
The lateral slit technique also helps enable a surgeon to determine the direction of the graft incisions. This then determines the ultimate direction of the transplanted hairs growth. Thus a surgeon can use this technique to control and vary both the direction and angle at which the transplanted hair will grow in order to mimic the subtle changes in hair direction that occur naturally.
Each graft incision is created by analyzing the neighboring hair so the surgeon can reproduce the correct hair pattern. As a result, as each transplanted hair emerges from the scalp it will grow and lay in a similar direction as its neighboring non-transplanted hairs.
Lateral slit incisions also tend to be more parallel to the scalp and thus more superficial and less invasive to the scalp’s underlying vascular structure. This parallel alignment also enables a physician to place more grafts per square centimeter with out the grafts compressing or popping up since the pressure exerted on the grafts does not push them upward from the scalp.
Some of our members use custom blade cutters to create tiny blades to make incisions that match the size and depth of each follicular unit graft being transplanted. This enables a surgeon to safely dense pack more grafts into a given area during a surgical session. Healing time is also more rapid, with minimal scarring.
Typically most clinic’s blades range from 1.5mm to 2mm in size. However, by using the custom blade cutter our physicians can create blades as small as .7mm for a single hair graft and .9mm for a multi hair graft.
In addition, the blades created by the custom cutter are squared off to match the shape of the bulb end of a hair follicle. Non custom cut blades are typically spear pointed which requires them to be inserted deeper thus causing more trauma to the scalps vascular structure.
The ability to control the depth of the incision each blade makes is also critical. Each blade is placed in a blade holder that is set to not allow the blade to go any deeper than required for the graft to being placed in the incision. This minimizes unnecessary trauma to the deep vasculature of the scalp, thus enabling close tight incisions, minimal tissue swelling, and quick healing that leaves no visible scaring, pitting, or cobble stoning of the scalp.
The plane and direction in which each follicular unit graft is placed on the scalp can also impact the ultimate appearance of density that can be produced with a given number of grafts. This is because hairs within a follicular unit are typically next to each other inline.
Therefore by arranging each multiple hair graft on the scalp in a linear fashion to the line of sight, each follicular unit will provide the maximum appearance of fullness and scalp coverage. This also mimics how hair is normally aligned on the scalp.

ElectroTrichoGenesis (ETG), also known as Cosmetic TrichoGenesis (CTG), is a little known hair loss treatment that makes some very lofty hair growth claims. How does ETG work and is it really clinically proven to treat androgenic alopecia(genetic balding)?
ETG is promoted as a safe, painless and non-intrusive. Treatment is administered via an “ergonomically shaped couch with a semi spherical hood” manufactured by Current Technology Corporation in Vancouver, Canada.
The patient reclines on the chair and the hood (with disposable liner) is placed over the head but does not make contact with the scalp. This special hood contains electrodes that deliver “specified pulsed electrostatic energy” delivered passively to the scalp by the low-level electric field generated within it.
ETG is believed to stimulate the regrowth of hair through the positive influence of the pulsed electrostatic field it generates. This field is said to stimulate “changes within the hair bulge and the follicle, stabilizing hair loss and stimulating new hair growth”. Patients receive a single 12 minute session weekly.
The following three studies on the efficacy of ElectroTrichoGenesis (ETG) as a treatment for thinning hair have been published in peer-reviewed journals:
Maddin, W. Stuart; Bell, Peter W.; James, John H. M. (1990).
"The Biological Effects of a Pulsed Electrostatic Field with Specific Reference to Hair Electrotrichogenesis". International Journal of Dermatology29(6): 446–450.Benjamin, Benji; Ziginskas, Danute; Harman, John; Meakin, Timothy (2002).
"Pulsed electrostatic fields (ETG) to reduce hair loss in women undergoing chemotherapy for breast carcinoma: A pilot study". Psycho-Oncology11(3): 244–248Maddin, WS; Amara, I; Sollecito, WA (1992).
"Electrotrichogenesis: further evidence of efficacy and safety on extended use". International Journal of Dermatology31(12): 878–80
According to the 36-week comparative, controlled study conducted on male subjects at the University of British Columbia and published in The International Journal of Dermatology, 96.7% of those treated experienced cessation of hair loss and/or hair regrowth. Decreased hair loss was seen as early as 4 to 6 weeks but many patients required more time for results.
The pilot study conducted on women undergoing chemotherapy for breast carcinoma and published in Psycho-Oncology,showed that twelve out of 13 participants had good hair retention throughout the chemotherapy period and afterwards with no reported side effects.
As with the clinically proven medical hair loss treatments Rogaine (minoxidil) and Propecia (finasteride), ETG is said to be most effective in the early stages of balding.
Although the data put forth in this article seems to paint ETG as a clinically proven and highly effective hair loss treatment, it’s important to note that the procedure is not new. The studies referenced above were published more than 13 years ago. If ETG truly works to stimulate hair growth and suppress the advancement of hair loss, why has it not become a fixture in the world’s leading hair restoration clinics? Where are all the glowing, unbiased reviews?
With no reported side effects, there may be no harm in giving ETG a try if there is a provider in your area and the fees are reasonable. However, balding men and women are encouraged to consult with an experienced and reputable hair restoration physicianin order to diagnose the cause of their thinning hair and learn about the outstanding medical and surgical options available today.
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.
Try telling that to 80 million men and women who are suffering from hair loss in the United States. They will laugh at you. Yet on a daily basis we are bombarded with ads for hair loss treatments like Avacor, Hair Genesis, Fabao and Procerin that use misleading advertising to sell their products. Thanks to their persuasive messages promising to regrow hair, consumers will spend nearly one billion dollars trying to find an effective hair loss remedy and fall victim to misleading advertising like this.
Thinning hair is a source of distress for millions of men and women so it is not unusual for them to seek help from anything that sounds like it will work. Most questionable hair loss products use similar, misleading marketing techniques ranging from claims to testimonials and photos.
Many hair loss products claim to be able to restore hair through the use of drugs, herbal lotions or other exotic applications like lights, lasers or electrical fields. While many of these products have been around for years, there is little evidence that they can restore hair.
How are they allowed to make such claims? These products often use small amounts of generic drugs found in Propecia and Rogaine (finasteride and minoxidil) which allows them to make the claim to stop hair loss or they imply hair growth with 'cosmetic' claims.
Some hair loss products lead you to believe that they can stop hair loss by parsing their words. They can't come out and claim to regrow hair or stop hair loss, so they advertise vague claims like "thicker, fuller hair". This is a 'cosmetic' claim that any product can make. Be advised that cosmetic claims cannot restore hair or grow hair because they are not proven to do so.
With the anonymous nature of Internet postings, people posing as users will mislead others with false testimonials. Often, positive reviews are produced by people compensated to post these messages. Since there is no real regulation of online postings, consumers are advised to take testimonials with skepticism.
Most product advertising that claim that you can "Regrow Hair!" or make your hair 'thicker and fuller' and show a photo of a balding person with thin hair next to a photo of the same person with thicker hair covering the baldness. Photos don't lie, do they?
Well, yes they do.
You can prove it yourself. Take a photo of a head with thinning hair using a flash camera and then photograph the same head without the flash. The photo with the flash will look like a bald head and the photo without the flash will look like more hair.
Lighting, length of hair and how the hair is arranged on the head determine whether a photo of a head looks bald or not. Most people go through the same routine as balding advances: they push hair from here to there and hair spray it into place in the hope that no one will notice that we are going bald. To the extreme, this becomes the 'comb-over' hair style.
Review the photos of hair loss products you've seen. In most cases there will be just a few and they will all have misleading elements like lighting, hair style and length of hair in the 'before and after' photographs. If the products or services are really legitimate, there should be dozens of photos, if not hundreds or thousands.
Sadly, we think that the United States Food and Drug Administration and the Federal Communications Commission (agencies who regulate such issues) can stop these scams. Unfortunately, they can't. Since the FDA approved Minoxidil and Finasteride as effective in stopping hair loss, any inclusion of these products in any form enables marketing companies to make hair restoration claims.
Even the studies done for Rogaine and Propecia are not that encouraging. When Rogaine was studied (active ingredient is minoxidil), 16% of the placebo group had measurable new hair growth. Four out of twenty-five people had real, measurable hair growth when they believed they were using something that worked. Both studies were limited in time and scope. To read the studies that were done achieve FDA approval, visit the FDA web site and scroll down to Propecia and Rogaine. (http://www.fda.gov/cder/foi/nda/index97.htm )
If a person is genetically prone to hair loss and balding, FDA proven hair loss treatments may help slow the process if they are used early and often. If you are like many and have already lost more hair than you're happy with, there is only one option to restoring your own natural hair: hair transplants. Hair transplants have become an art in the restoration of natural hair which is genetically resistant to the causes of balding.
Like any surgical solution, your success depends upon the quality of the doctor you choose. Doctors who are successful in restoring a natural looking head of hair are carefully reviewed by the Coalition of Hair Restoration Physicians for membership in this exclusive organization. They must allow access to past patients, confirm their training and provide photos and videos of their patients.
While hair transplants are not possible for everyone, they are now more natural and affordable than ever before.

Maybe you’ve heard that wearing a tight baseball cap too often will make you bald or that if you wash your hair too much you’ll suffer hair loss. Well, they’re both old wives’ tales.
So what really causes hair loss and what’s myth?
The idea of brushing the hair 100 times a day to stimulate the scalp circulation is a fantasy. In fact, if you brush your hair too much, you may end up injuring and losing hair.
This myth stems from the thought that hair loss was due to poor circulation and that brushing or massaging would improve blood flow and nutrition to the follicles. The truth is, bald or not, there’s no major difference in scalp circulation.
There’s some truth and some fiction when it comes to hair styling and Hair Loss.
It is true that certain hair styles, such as corn-rows or tight ponytails, can cause hair loss. These styles put undue tension on the hairs. But as for hair sprays, perm solutions, or coloring resulting in hair loss there’s no truth to that idea. These applications may cause some damage to the hair strands. But the all-important follicles, located under the skin, stay safe.
And what about the idea that haircuts will make your hair grow back thicker and faster? That’s wishful thinking. Everyone’s hair growth and length depends on their own unique hair cycle, which is based on both nutrition and heredity. The longer your growth phase the longer your hair growth.
What about hair dryers? Are these follicular incinerators?
The good news is there is no evidence that hair dryers cause thinning hair. However, too hot or too much drying may lead to brittle and breakable hair. Let common sense guide you and hold the hair dryer at a normal distance from your scalp and dry to your heart’s content.
Think about this – if you were losing hair because of a lack of vitamins or minerals in your diet, why wouldn’t the back and sides of your head be affected? In actuality, vitamin deficiency results in an even distribution of hair loss all over the head. Of course, it doesn’t hurt to take vitamins on a regular basis for your overall health.
Your follicles width and amount are based on heredity. So claims of hair growing miracle drugs or natural hair loss treatments are untrue.
However, steroids use can cause hair loss. Research has proven that anabolic steroids raise the levels of baldness-inducing male hormones. For those who are genetically prone to hair loss, this can speed up the loss in as little as 3 to 6 months. While this loss may be reversed, it can be permanent.
Unfortunately, there is no truth to the idea that the more sex you have, the less hair you’ll lose! And the same goes for the rumors that the chemicals released during sex can affect hair loss. Science has yet to uncover any proof to this fantasy. But that doesn’t mean you shouldn’t keep experimenting.
Many men believe that if their father has a full head of hair, they’ll keep a good head of hair. But hair loss or hair growth is set by a genetic combination determined by both sides of your family.Of course, if your family tree is filled with balding scalps, you do have a better chance of losing hair.
While hair loss sufferers spend small fortunes on treatments based on myths, there are several proven treatments, non-surgical and surgical.
Currently there are only two non-surgical hair loss treatments that are FDA approved for Hair loss. These two are Propecia (Finasteride) and Rogaine (minoxidil).
Other treatments may or may not help stop or reverse hair loss, but they are not formally approved by the FDA
