I have heard that it is recommended by some hair loss docs after surgery and some even give patients one to use during the first few months after surgery? Here is an excerpt from an article from the web:
Dr Glenn Charles, DO, a Florida-based hair transplant surgeon, became intrigued with the device and its possible uses. He wondered if in addition to helping patients with hair growth, the LaserComb 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.
Dr Charles approached the company with his interest and conducted clinical trials on some of his patients where he monitored their hair counts, hair color, and overall health of the hair and scalp.
In a separate study that he conducted on 20 of 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.
