This insightful hair loss article was written by
hair restoration forum member “HLBD”. Below he shares with us a piece of what he has learned in researching real hair restoration solutions for his
hair loss condition.
I know that there is a lot of skepticism towards laser hair treatment on our
hair loss forum and my view although Im not endorsing or supporting the use of any low level laser therapy (LLLT) product is equally unpopular simply because I believe, from a scientific standpoint, there is not enough evidence to validate nor dismiss claims of effectiveness and so I refuse to outright condemn laser therapy as a treatment until further investigation is done.
History of Laser Therapy for Hair Loss: In 1967, shortly after the first working laser was invented, a researcher named Endre Mester with the Semmelweis University of Budapest developed a theory that exposure to cold laser light would, eventually, lead to cancer he theorized that melanoma (a malignant form of skin cancer) was likely to form from exposure to these cold laser light bands, similarly to exposure to UV radiation emitted by the sun. To test his theory, he shaved a group of mice and trapped some of them in a cage with constant cold laser light exposure and left the other half as a control group. To his surprise, the light didnt cause cancer in any of his animal subjects; however, the mice that were exposed to the laser light grew back their shaved fur much faster than the control group. Mester named his discovery laser or photo (light) biostimulation as he theorized that, somehow, the laser light had stimulated the hair cells into an excited state of hair growth. Simply knowing this, however, is not enough for us to assume that laser hair treatment would be a satisfactory treatment for male pattern baldness (MPB). The first problem is that animal studies are notoriously unreliable. Secondly, mice do not suffer from MPB. Finally, just about anything can make a mouse grow hair.
Problems with Validating Laser Therapy as a Hair Loss Treatment For the validation side of the argument, there are plenty of problems:
- Most of the pictures presented to provide evidence are circumstantial (submitted by users of the therapeutic products) and are often taken under different conditions head positions different from before and after photos, different lighting, different hairstyles or colors, and/or no visible change.
- The FDA approval was not actual approval the permission to market and clearing of the Hairmax laser comb was given as conjunction approval based on the devices similarity to other previously cleared devices. Furthermore, though many internet sites selling low level laser therapy combs and brushes attempt to mislead customers into believing that the FDA approves and cleared all LLLT devices, the FDA does not approve or permit the marketing of any therapy enabled by a device, but the device itself this is the reason I cant just start making pacemakers and selling them online, saying that the FDA approves of electrocardiopulmonary regulation. The most important factor in approval, marketing permission, or clearing of any medical device, according to the FDAs medical device division is the manufacturing of said devices; the device must follow GMP (good manufacturing procedure): a set of standards established to insure health and safety of the products manufactured).
- There is no evidence as to how LLLT therapy works, if it does work.
Problems with Dismissing Laser Therapy as a Hair Loss Treatment
On the dismissal side, there are also some issues:
- Most opponents of the laser therapy for hair regrowth offer no scientific evidence to back their claims that the devices are ineffective. One physician has mentioned time and time again that these devices do not work because they do not concur with common sense. Speaking as a former member of both high school and college debate teams, this argument wont win any debates. I cant show anyone common sense. I cant point to common sense on a chart and, although Ive known many people with sense, I can say with all certainty that it is not a common trait then again, I do a lot of work on the internet these days. True men of science cannot afford the luxury of common sense.
- Although most of the information is circumstantial, there is a lot of it and some of it is quite convincing. I recall watching a news segment of a young camera man who agreed on the spot to try an laser hair treatment therapy at a local clinic on which the news agency was reporting and, if there was no trickery involved, the young mans progress was well documented and impressive. He started out maybe a level 3 on the norwood scale and regressed back to a norwood level 2 or 1.
The point is that there is not really enough evidence one way or another to determine whether LLLT is an effective treatment for baldness and most respected proponents only recommend its use in conjunction with other treatments.
The debate does put me in mind of a device that once came through our lab for independent validation study. Before I tell you what the device was, perhaps I should tell you that many researchers and assistants did crack some jokes as the device was a penis stretcher or penis traction device. Long story short, the results of our studies did indeed prove that the device did work as its manufacturer claimed (men gained between one and three inches in length over a year period). Its claim was actually scientifically sound as most of the bodys tissues are remarkably elastic and do respond to traction. Some of the sites marketing the devices are, however, misleading.
The devices work by causing microscopic rips in the tissue at the cellular level. This prompts the cells to divide and heal the breach with more tissue. This will, with time, engorge and enlarge the tissues to which traction is applied. Although most of these sites claim that the procedure is similar to neck stretching that is done by some remote tribes, it is actually closer to ear stretching that has been popular recently in urban cultures.
Still, despite our study and numerous others contracted to validate the penis traction device makers claims and their successful outcomes, many opponents claimed and still state that there is no way the devices could work. Much like the naysayers above, none of these people could provide any reasoning as to why they believed the devices would not work. Also, like the laser therapy devices, many among the opponents were and are medical professionals who also have no evidence or logic to support their opinions. In my book, an uninformed and unaware opinion fails by its very nature to be a professional opinion.

I would agree that hats do not have a negative effect on hair growth, either your natural hair or follicular unit grafts that have been transplanted.
