HairMax recommends that their laser devices be used 3 days a week, indefinitely, for best results. According to the company, research findings have indicated that the use of the devices for more than 3 days a week did not provide additional benefits for hair growth.

Results: Of the 110 patients who completed the study, subjects in the HairMax LaserComb treatment group exhibited a significantly greater increase in mean terminal hair density than subjects in the sham device group (p < 0.0001).

A: The HairMax LaserCombs & HairMax LaserBands 82 & 41 are equipped with a rechargeable battery and once fully charged (in 2-3 hours) they can be used for approximately 10 hours of continuous use. When the battery requires charging, the laser devices will turn off.

So while some grey haired people who have reported that the HairMax worked great in stimulating hair follicles and regrowing their hair, some say that the hair that they was regrown, came back dark!
