CROOT Hira Shouwu Reverse Bar for Gray and Damaged Hair - Darkening Shampoo Bar (2 PCS)

This is Not the Secret to Eternal Youth! I would give this soap a resounding ZERO! If it truly reversed gray and white hair, it would be groundbreaking—on par with the invention of the wheel or the light bulb! Everyone would be talking about it, and it would be featured on every major news network, and talk shows. This is a colossal deception! Don’t waste your time or money. The product not only fails to deliver, but it also has an unpleasant odor. Save yourself the trouble—this is a scam, and I regret falling for it. Using this was a complete disappointment!

My husband at age 76 uses this shampoo soap for a year and his new hair grows out in solid black. The lady who cut his hair was so surprised and asked what did he do with his hair? He told her about the soap and since then the words spread to her customers as a true evidence. It is amazing.

Almost through the first bar. It has been over a month and I have short hair. Have had 2 hair cuts and the grey is just as grey as it was a month ago. Does not do anything to giving your hair any color. But it does lather really well and cleans like a decent shampoo.

I would so that this soap you'll have to use a awhile to see results

Ok so to be honest, I have received a few compliments on my hair over the past couple of weeks and at least my hair doesn’t seem to be thinning as much so I suppose that is a positive. However, it does not… DOES NOT… reverse your gray hair to its natural color nor does it color your hair. I am still showing the lovely grays in the same area I was and I have been using this product for over a month.

I think this covers my Grey's, but you should leave it in for a couple minutes. This brand doesn't lather as much as other brands, but I like the way my hair feels after - really soft and healthy! I gave it 4 stars just because it takes effort to get it to lather up.

Really I don't know this thing doesn't work at all it's like throwing money in the trash can

I used Just for Men shampoo for several years, which worked well. I thought I'd change products to something organic. I bought this product based on the reviews. I used the product for three weeks. All it did was strip any color Just for Men gave me and left me with gray hair. I stopped using it, went back to Just for Men, and am now content.
