It's the placebo effect. I had them try it on me and if you go in believing that it may work it will. Then when you do it again and you are just like 'I want to try this again.' and come in thinking it's a hoax it won't work. It's snake-oil in bracelet form, it'll regrow your hair, help you sleep better, increase your intelligence, and make your wallet feel a little lighter. Haha.
