A Florida-based hair transplant surgeon, Dr Glenn Charles, DO, conducted a series of clinical studies using the Laser Comb to determine the effectiveness of the device and it's possible uses. He wanted to find out if in addition to helping patients with hair growth, the Laser Comb could help speed up the healing process and minimize scarring in hair transplant patients.

He also wanted to determine if there was less postoperative shock fall out (telogen effluvium) in hair transplant patient after using the device. To verify his data in a professional manner, Dr Charles conducted clinical trials on some of his patients where he monitored their hair counts, hair color, and overall health of the hair and scalp.

One clinical trial which was submitted to the FDA clinical trial involved five male subjects with ages ranging from 21 years to 59 years. All the participants were experiencing hair loss and were not taking any medications or using any products related to hair loss. (Propecia, Rogaine, or Avacor). Each patient had two areas tattooed, one in frontal region and the other in crown (back of head) region. Manual and computerized hair counts were taken at beginning of study and again at 4 months.

Any changes in hair or scalp characteristics were also noted. In all subjects there was an increased hair count with the average increase being between 40 to 55%. Two patients also noticed a darkening of hair (decreased amount of gray hairs), One patient noted significant improvement of scalp dryness (flakiness) two participants noted no noticeable changes in the hair or scalp characteristics. There were no negative side effects or other complaints expressed by any of the subjects involved with the study.

In a analysis that he conducted on his hair transplant patients, Dr Charles attempted to determine if patients who used the LaserComb immediately following surgery healed faster, had less shock fallout of original hair, and faster growth of transplanted follicles. Each patient in the study was instructed to only apply the laser light to the right side of the donor and recipient areas for 10 minutes each day. Follow up visits with comparisons of right and left sides were taken at 1 day, 1 week, 1 month, and 6 months. According to Dr Charles, in all patients postoperative redness of scalp faded faster on the laser treated side. There was also less shock fallout and faster regrowth of newly transplanted follicles in all but 3 patients. In these 3 patients there was no measurable difference between laser treated and untreated side.

After reviewing results of both studies Dr Charles feels very confident that the lasers cause no harm. (There were no adverse reactions or patient complaints from either study group), and that a significant percentage of people will benefit in one or more ways by using Laser Light Therapy. In hair transplant patients he feels that this may include decreased shock fallout of native hairs, quicker return to normal pigmentation of scalp, and faster growth cycles of the transplanted hair follicles. In non-transplanted patients there can be improvement of scalp dryness and flakiness (patients with seborrheic dermatitis). There may also be an increase in hair shaft diameter along with an increased number of total hair follicles. Some patients may even see more of their original hair color (pigment) after using the LaserComb. Overall, almost all patients felt that their hair and scalp felt healthier and fuller after using the Hairmax LaserComb.
