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

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 hair transplant costs are vastly better value, than they did just a few years ago. Increased competition combined with the increased ability of a specialized clinic to produce large sessions of follicular units at reduced hair transplant costs and has resulted in patients getting vastly better results and increased density at lower prices.

Just a few years ago it was not unusual for a clinic to charge as much as $15 US per graft, while providing patients with only small sessions of a few hundred grafts that achieved limited density and fullness.

Today hair restoration clinics typically provide free no obligation consultations, with surgical sessions priced either per graft or by the session. Hair transplant costs typically cost between $3.00 to $8.00 per graft, with $5 to $6 per graft being about average.

It is normal for the price per graft to drop as the size of the surgical session increases. Many clinics will offer a reduced rate per graft once a certain surgical session size (i.e. 1,000 or 2,000 grafts) is exceeded.

Comparing the costs of various hair loss treatments

Although hair transplant surgery is not inexpensive, it can be the best hair restoration value given that the results are natural and last a life time. The cost of non surgical solutions like a hair system or hair loss medications can exceed the cost of hair restoration surgery when the long term costs are compared.

For example – A quality custom hair replacement system on average costs $1,200 and needs to be replaced about once a year. In addition, a hair replacement system requires regular upkeep and reattachment each every 5 to 6 weeks at about $75 per visit or $675 per year.

Thus the cost of buying and maintaining quality hair replacement systems over 15 years is approximately $28,125.00 ($1,200 plus $675 in annual upkeep = $1,875 x 15 years = $28,125.00). This total cost well exceeds the typical cost of surgical hair restoration.

Note - Of course the cheapest option is shaving your head with an actual net saving due to no expense for shampoos, conditioners, combs, brushes, or hair stylist.

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.

Men and women who have the impulse to pull their own hair out may be suffering from trichotillomania. Trichotillomania is an impulse control disorder characterized by the repeated urge to and behavior of pulling out one's own hair. Impulse control disorders resemble substance addictions because the patient feels out of control of his or her own behaviors. Men and women with trichotillomania live relatively normal lives but typically show signs of hair loss, thinning, and bald spots all over the scalp and body from pulling it out.

Treating trichotillomaniagoes far beyond trying to stimulate hair regrowth.Even if Rogaineor laser therapy for hair losswere to regrow hair, there is a strong possibility that trichotillomania patients will continue to pull their hair out. Patients with trichotillomania therefore, should be treated at the source of the disorder in conjunction with using proven hair loss treatments.

In addition to medication, Habit Reversal Training (HRT) by a trained counselor has proven to be successful in treating trichotillomania. With Habit Reversal Training, the individual is taught to recognize and redirect their impulse to other more constructive activities. Often times, trichotillomaniapatients are asked to keep a journal of their hair pulling episodes. This can help the counselor and patient to identify and develop strategies to avoid situations that might trigger hair pulling episodes. Journals often include the location of the incident, number of hairs pulled, date, time, and their feelings and thoughts during the episode.

Treating a trichotillomania patient's baldness may be done simultaneously or after proper treatment of the disorder. Rogaine (minoxidil)can be a helpful aid to HRT by stimulating the follicles underneath the scalp, potentially facilitating or expediting hair growth.Treating a patient’s hair loss while they continue to pull their hair out is not constructive. Since this type of balding is not genetic due to the production of DHT, Propecia (finasteride)won't likely help.

Patients who've suffered from trichotillomania for awhile may damage or even remove the hair roots by excessive pulling, making non-surgical hair regrowth next to impossible. Surgicalhair restorationmay be an option for trichotillomania patients whose hair roots are too damaged to produce new hair on their own. Hairrestoration surgeryshould be reserved only for patients who've been successfully treated and no longer suffers from trichotillomania.

Catching and treating trichotillomania early will most likely reduce damage done to the hair follicles and eliminate the need for hair loss treatment, since undamaged hair will return on its own.
