My husband has been using ControlGX by Just for Men and I can see it reducing his grey hairs. He has been using it for 3 weeks and his grey hairs are not as noticeable. He really likes this shampoo and has recommended it to his friends.
My husband has been using this product for a while now, and although it may be gradually darkening his gray, it is leaving an absolute mess in my bathroom. It stains surfaces it comes in contact with. My white tub now has dark stains from this product. Bummer.
My husband tried this and you could see a difference after the first shampoo. However he is tall and it did get on the ceiling of the shower as well as the shower curtain and is not easily cleaned.
