Laser Brush and Fertility?

I am interested in investing in a laser brush for my hair, but wanted to know whether they were all more or less the same. Also, is there a possibility that this could affect fertility at all? Please advise. Regards

I doubt that the Laser Comb has any negative effects, including any effects on fertility. Low laser light is not like radiation, so its depth of penetration is very limited. Think of it like a flashlight, where it shines is where any effect may be. The major effect may simply be that it does not work. I believe that the portable devices are all similar to each other, so nothing stands out to me. They all may not work.
