Probably related to some of the work by Dr. Cotsarelis (of Follica). While I'm sure there is way more to his statement than we can understand, he says:
“When cells move in to close a wound, they are trying to make a decision: Should I make epidermis or should I make a hair? If there is a lot of Wnt around, they choose to become hair follicles.”
Interesting! I guess my cells have mostly decided to make epidermis lol. I might give WNT a try; I can't see what harm it could possible cause.
