I hate when some IDIOT gets on here and say something REALLY STUPID that NO ONE wants to hear. With "there's no scientific proof that this works for any thing!" Well I have two things to say to that. One- I have hair that I feel grows very slowly even though I'm very heathy eat healthy, not on ANY meds, DON'T and NEVER has been a drinker or smoker, drink PLENTY of water and take ALL natural vitamins. I purchased this for pain in my neck and upper back from an engery and in like the 2 1/2 months my hair grew about 3 1/2 inches. Longer than it grows in 4 years without this powder. I was shocked!!!! ( and I'm African American ) for anyone wondering. I would have taken before & after pics if I had any idea this would have that effect on my hair!!!! Two-I have a dear brother that HAD brain Cancer (proven by doctors and hospital stays) and that was years ago. He does not have any brain Cancer anymore. They said he would be dead. (He even refused all their Cancer treatments!!! ) Well he's NOT and there is NO SCIENTIFIC reason why he's NOT!!! So science can't explain or prove everything in God's nature. SO IF something works for some it works. It does not have to be because science said so. Be grateful people are finding and getting relief!!!! And STOP being a hope destroyer for others quest for finding much needed help!!!!
