2 PCS Organic Harishow Hira Shouwu Shampoo Bars for Gray Hair, Darkening and Growth Promotion, Unisex Hair Care

does ABSOLUTELY NOTHING! Total scam.

Scent is strong but not bad and hasn’t irritated my allergies. The lather is incredibly awesome. My hair feels so clean. I have noticed less grey growing and feel like my hair is getting thicker. It’s definitely growing better. I have had to up my conditioner use but I am not completely sure it’s the shampoo or the lingering dry winter. I also think the bar is gonna last just as long or longer as my usual annual liter of shampoo. In 3 months, the bar has hardly shrunk at all!

Does not work on my grey beard

It's a good product, however, it doesn't darken your hair. My husband has been using it for 4 months but I dont see change in his hair color. It's still pretty grey.

Really didn't work for me.

It’s amazing when you get this round bar of shampoo. It really lathers quite quickly and may last a long time IF you keep it out of water except when using it. I just wish I knew more about the ingredients. I think it is worth a try.

This product didn’t workout for me, still have grays 👎🏾

I love how clean my hair feels after using this soap and how richly it lathers but it has done zilch for my greys. I gave up regularly shampoo and will continue to wash my hair with it, maybe one day it will take care of my greys.
