Follicular unit extraction is a minimally invasive procedure for performing follicular unit hair transplantation. However, unlike the predominant follicular unit transplant procedure, in which a strip of donor tissue is removed and dissected under magnification, the FUE procedure uses a small punch to extract each follicular unit one by one.

Both the strip excision and FUE procedures create 1, 2, 3, and 4 hair follicular unit grafts that are then transplanted into the balding area in the same manner. The primary difference between these two procedures is the technique used to harvest the follicular unit grafts.

Comparing the Strip Excision procedure to the Extraction (FUE) procedure

The common strip excision method of performing follicular unit hair transplantation involves surgically excising a thin horizontal strip of bald resistant skin from the donor area.

Strip Excision Procedure 

Donor strip being excised

Incision sutured together

Hair combed down after suturing

This donor area is then sutured together. These sutures (either stitches or staples) are then typically removed about ten days after surgery. Some physicians use dissolvable sutures so that no removal is needed.

Once this linear incision is fully healed the patient is left with a thin horizontal scar in the back of the head. This scar is typically hard to detect since the surrounding hair conceals it, even when the hair is cut short.

How the FUE Procedure is performed

With the Follicular Unit Extraction or FUE procedure 1, 2, 3, and 4 hair follicular unit grafts are carefully extracted one at a time using a tiny punch of one millimeter or less. Often the surgeon requires the patient to buzz cut a portion of their donor area so that they are able to see the patient’s scalp.

The follicular units are extracted

The follicular units are extracted by placing the punch around a single follicular unit and cutting a small circle through the skin around that follicular unit. The follicular unit is then gently pulled up and away from the loose tissue underneath the skin.

The small hole left behind after the follicle is extracted then heals over the following week. Normally this small round incision contracts as it heals making the resulting round scar smaller than the size of the 1mm punch that made the incision. The FUE patient ultimately ends up with hundreds of small round white scars, which are normally not detectable once the patient’s hair grows out.View a video of an actual FUE surgery.

To Extract or to Excise, that is the question.

Advocates for the relatively new FUE procedure claim that this procedure produces less noticeable scarring and no tightness or numbness in the donor area since no donor tissue has been pulled together and sutured. Many patients and physicians find the claim that FUE produces less visible scarring to be debatable.

Some physicians and patients also have concerns about the relatively new FUE procedure, such as the lack of formal studies regarding the percentage of follicles that may or may not be transected during the sight unseen extraction process.

In addition, since the physician must personally extract all follicles, one by one, the FUE procedure is very physician dependent and thus very expensive. The FUE procedure also requires considerably more time in surgery to move a given amount of hair to the balding area.

The standard strip excision procedure has the advantage of utilizing a collaborative team to carefully create the grafts once the donor tissue is removed in a strip. This collaborative approach enables a well trained staff to do sessions of 2,000 to 3,000 all follicular unit grafts in a single day. This team approach enables a patient to get a much larger number of grafts/hairs in one sitting at a much lower cost per hair than with the FUE procedure.

However, some believe that despite being relatively costly the FUE procedure may be appropriate for patients who have very limited elasticity in their donor area or who only need a small number of grafts.

Today's evolutionary high point - Ultra Refined Follicular Unit Transplantation

By relocating these carefully prepared bald-resistant follicular units, physicians doing "follicular unit hair transplantation" recreate a natural pattern of hair in the balding areas.

To do this properly is a very time consuming and exacting process. It requires a team of meticulous medical technicians working hand-in-hand with the hair transplant surgeon in a very lengthy surgical procedure.

Ultra Refined Grafting - Smaller Blades, Smaller Incisions, Smaller Grafts

Today's micro surgical blades, like the size of hair grafts, have become ever smaller and now enable hair transplant surgeons to safely make more tiny graft incisions in a given area then ever before. Surgeons are then able to "dense pack" select areas with as many as 40 to 60 follicular unit grafts per square centimeter. This graft density is as much as twice that of the standard follicular unit hair transplant procedure.

Such high densities of transplanted hair typically produce the appearance of fullness even after only one surgical session. Patients also experience rapid healing and no visible skin distortions due to the tiny size of these incisions.

Ultra Refined Follicular Unit Grafting - Hard on the clinic but easy on the patient.

Ultra refined follicular unit grafting raises the bar for physicians and their staff. This delicate and demanding hair transplant procedure requires more skill and careful attention to be performed properly. The smaller and more tightly packed incisions require more closely dissected follicular unit grafts that are carefully trimmed under microscopes. These small and densely packed incisions are also more difficult to place the grafts into.

This procedure also requires more careful patient selection, as "dense packing" of grafts is not appropriate for all patients.

Ultra Refined Follicular Unit Transplantation - the new "Gold Standard"

In the hands of a highly skilled physician and staff the Ultra refined follicular unit hair transplant procedure can achieve excellent new hair growth that is so natural that it is undetectable even under close scrutiny.

While the standard micro "follicular unit" hair transplant does produce natural looking results, its ability to achieve high density in only one surgical session is limited. Thus patients may have to do subsequent surgical sessions in a transplanted area to achieve a full look.

The many patient benefits of this new ultra refined procedure are significant and include:

• The ability to get excellent hair density in only one surgical session.
• Minimal trauma in the graft recipient area with rapid post surgical healing.
• Little or no visible pitting or distortions in the transplanted areas.
• More natural direction and angulation of the transplanted hair.

All physician members of the Coalition perform Ultra Refined Follicular Unit Hair Transplantation.

While many hair transplant physicians perform quality follicular unit hair transplants, only some of them are capable of performing large sessions of ultra refined follicular hair transplantation. However, all members of the Coalition of Independent Hair Restoration Physicians perform ultra refined grafting with excellent results.

The Future of Surgical Hair Restoration

The amount of hair you can transplant is ultimately limited by the amount of hair follicles you can safely relocate from the bald resistant donor area at the back and sides of your head.

Some day it may be possible for physicians to create multiple hair follicles from one original follicle. This process typically called Hair Multiplication or more incorrectly Hair Cloning is currently being investigated by several research scientists and hair restoration physicians.

If and when this process is successfully developed patients would no longer be limited by the finite amount of bald resistant hairs that can be relocated from their donor area. Hair multiplication would result in a virtually limitless supply of hair available for hair transplants.

This would be especially good news for men or women with extensive baldness and a very limited supply of donor hair. Even those with extensive baldness would theoretically be able achieve thick full heads of hair.

However, experts believe that we are at least ten years away from hair multiplication being available, if even then. But perhaps some day scientists will be able to use gene therapy to halt the balding process without drugs or surgery.

Is it Effective in Stopping Hair Loss?

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.

History of Laser Light Therapy

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.

Laser Therapy as a Hair Loss Treatment

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.

Varying Opinions of Well Respected 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.

Recent Scientific Studies

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.

Laser Hair Therapy and FDA Approval

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.

It seems that lately, new hair loss treatments based on “revolutionary scientific research” hit the rumor mill on a monthly basis. Some of these treatments come to light via reputable scientific journals while others, like Recoverup, materialize one day with a flashy website, a lot of promises and very little verifiable data. Recoverup is a UK based company that claims to offer stem cell treatments for hair loss through clinics in Taipei, Taiwan and Penang, Malaysia. According to their website, this treatment is so quick and easy it can be performed in a single day with startling results visible in only one month. Does this sound too good to be true?

Recoverup’s baldness treatment process claims to rely upon Autologous Adipose Adult Stem Cells (AAA). Unlike controversial embryonic stem cell treatments, Autologous Adipose Stem Cells are derived from the patient’s own fat cells through a small liposuction procedure and are then grown into a culture to increase volume. These stem cells are then “differentiated” with “growth factors” and injected into the scalp in order to induce new hair growth. This multistage process from extraction to injection can be performed in two appointments scheduled in the same day.

The question is, does Recoverup’s baldness treatment really grow hair? They state that “Empirical data indicates patients would expect to see at least 40% of all treated areas showing one of four results; (1) darker hair (2) thicker hair (3) faster growing hair or (4) more hair per follicle. Overall the effect is of more volume, and density, in those areas which were treated.” However, the Recoverup website offers very little in the way of photo documentation. The few photos that are presented are of poor quality and covered in text making them very difficult to evaluate.

The estimated cost for the one day hair loss treatment is between $8,000 and $13,000 depending upon the area to be treated. However, if the area to be treated is sufficiently large enough to merit a second day of treatments then this fee increases. Recoverup states that the long-term effects of the treatment are unknown and are dependent upon such factors as the patient’s age and quality of the source stem cells. “However, as a general guide, in other areas of stem cell treatment, data indicates approximately 3-5 years of positive results from each treatment.”  Recoverup does offer a 30-day money back guarantee if a patient experiences no new hair growth but is also quick to point out that the results will vary. One can imagine quibbling over whether or not a single follicle that didn’t appear to exist prior to treatment would constitute success under their definition. In summary, assuming Recoverup’s AAA stem cell treatment does stimulate hair regrowth, a patient can expect to pay upwards of $13,000 plus travel expenses to Asia for a treatment that is, by their own estimates, about 40% effective and may last between 3 and 5 years. This hardly sounds like an attractive alternative or even supplement to today’s state of the art, ultra-refined follicular unit hair transplantation combined with the clinically proven medical treatments Propecia (finasteride) and Rogaine (minoxidil). It is recommended that patients approach all unproven, “revolutionary” medical treatments with cautious optimism. Androgenic alopecia is progressive and avoiding proven surgical and medical treatments in favor of experimental procedures may lead to further hair loss.
