Gray Hair Reverse Bar，Mane Gray Reverse Bar, Shampoo Soap for Women and Men (2 PCS)[Amazon-developed Certification] Compact by Design

Does not work. It’s a good beard wash though, that’s about it.

I've read many negative reviews on this. This product isn't like hair dye, it doesn't work immediately. Using it daily my graying has slowed and REVERSED noticibly. Give it a full month, wash daily and you'll start to see the change.

Used a month religiously, not even a slight change in color. My skin reacted to something I'm thinking was in the soap and caused a rash. Had to shave my beard 😡

Doesn’t work. Awesome lather but that’s about it.

I have followed the recommended use but I don’t think this soap makes my beard less gray. It lathers well and the smell is very faint. The soap also lasts quite a while.

Muy bueno

Works good, doesn't turn your hair black, but it does help

I have used it for a week and it's not good. Leaves hair clean and nice for about 8 hours then the hair feels oily but dry. I know that sounds odd but it does. The other person using it says the same. She has long hair and it goes from oily to dry at the ends. And if you wash your hair at night, when you wake it's all matted and all over the place. Perhaps it's supposed to be that way, I didn't know. But I certainly don't like it and neither does she. It does lather well and I used it along with their root enhancement (which I believe is part of the oily problem)
