mccounahey claims he uses it, but i think its a general assumption on this forum that he got a hair transplant.
I never used the actual regenix regime that claims to reverse hair loss, but i did use their pure balance shampoo and their essential scalp cleanser for about 3 months. Its not advertised or intended to stop hair loss, but it did leave my head feeling squeaky clean. Stopped using it because it was a little pricey and made little difference.
I have read a few testimonies that said regenix works, but for $150 a month, it is totally not worth it.
