My father has been using this shampoo for years and his hair was hardly grey and it was a great product. Recently, the formula has changed and his hair is turning a copper brown not black. Also, he had an extremely severe reaction to whatever was in the formula. His hair was itchy, his scalp was heavily wounded, red and sore, and he had some hair loss. He's been having this problem for more than 3 months. Will not be buying until the formula is changed.
Bottom Line: No, I would not recommend this to a friend
