edgar cayce recommended an herbal formula for a man who asked what could cure his graying hair. there is a company that makes the formula... my husband tried it - he's on his third bottle now. its working. the hair on the back of his head is almost black (was more than half grey). the strange part about it is how its working - its not making all hairs turn black again at the same time, but is going by location and working its way around the head and body. the hair on the back of his head has been almost completely restored to his black color (which is just incredible to me), while the hairs on the front of his head are still gray. he's been taking it for about 4 months. i can't wait to see where its going to work next :-)
this is the company that makes it (small company) http://www.cayceconcepts.com/ the formula is called sampson's hair.
