I’ve had several people ask whether it would be better to fit or shave off their hair so that the transcranial light device can penetrate further into the brain tissue.
I am a great fan of head hair. It looks lovely, feels nice and most importantly, it keeps your head warm. The has a lot of blood vessels close the to surface of the skin and being bald means that a lot of heat can be lost through the head. Hair serves a useful biological function as well as being of aesthetic value.
I would not recommend removing your hair, unless you have so little hair that the removal of the last strands will make no difference. If this is the case, then why bother! Keep those gorgeous strands.
Some people find that their head hair starts to regrow. Where there had been a shiny, bald pate, fuzz has started to appear. A comb may be required. Those remaining gorgeous strands might just proliferate. Don’t argue!
If you have a lot of hair, then flaunt it and enjoy it. Don’t cut it off or shave it off. You will still get red and near infrared light onto your brain cells. Remember that photobiomodulation works by the indirect effect as well as the direct effect.
