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

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.

Item does not work, after 1 soap it just make streaks of black on my hair

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.

Doesn't seem to make hair darker, but I love it as a shampoo.

Great product!

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)

I am 77 years old with medium dark brown hair. I didn’t start going grey until I hit on my 70 now. I am seeing much more grey hair than I have wanted to say so rather than dye my hair I look for a soap and I found this a lot of natural ingredients. I’ve just start using it and I’ve been getting compliments since the first sample. Not sure if it’s really covered much grey at this point, but it’s fabulous shampoo all natural and it makes your hair feel fabulous so if nothing else I will keep using it only because of the quality of the shampoo but we will see maybe it will cover more grey it’s only the second day, but I still want to give it five stars or maybe I’ll give it for this one

It is very convenient to pack in a bag and take it with you and not have to worry about spilling anything. It lost longer than a bottle of shampoo. It leaves my hair a lot cleaner and it don't wight down my hair and leve it flat.
