2Pcs Mane Gray Reverse Bar, Man Gray Hair Reverse Bar, Reverse Grey Hair Bar Shampoo, Grey Gone Soap for Men, Hair Darkening Shampoo Bar for Grey Hair

Product doesn’t work. Hasn’t helped any color in my hair. Thanks for ripping me off. I have used both bars of this with every shower and didn’t work at all. I want my money back!!!

This shampoo bar is the best out of all the trials so far. Nice lather, great smell. Unsure if it takes out grey yet for dark hair but color is returning to blond hair turned white. I'd use it even if it were just to clean with.

It simply doesn't work. Bamboo charcoal is the media they use as a dye. Even if charcoal did act as a dye the concentration in the product isn't sufficient to actually work. I'm sure the seller will post reviews or hire a company to give it rave reviews. Believe me or not, it's your money.

Thoroughly rinse out no change in color.

I got two bars, each bar lasts about 2 months. I have been using it for 4 months. With no change in hair color

I'm getting old, my facial hair is greying I thought this would be a nice way to put off that process and extend what dark hair remains. It's nice facial soap, it smells nice doesn’t work to darken hair unless it is wet and on your face, I bought two and I am almost finished with my second bar and surprise, surprise, surprise, I still have my grey facial hair, no darker at all.

Total fake and gave me a rash.

Great lather and my hair feels better than ever. I think it’s helped decrease the grey as well.
