Hair Darkening Shampoo Bar, Shouwu Blackening Shampoo Soap for Gray Hair, All nature Organic (2 Pack Polygonum Multiflorum for Grey Hair)Compact by Design (Amazon-developed Certification)

I love this shampoo! It leaves my hair squeaky clean and just a couple of swipes over your hair creates a silky lather that leaves my hair soft and smelling good. I've always disliked the greasy feeling some shampoos leave behind, but this bar shampoo is amazing. I've got dark brown hair with a lot of gray. This shampoo doesn't darken the grays to my dark brown natural color, but it takes its brightness out and slowly turns my gray hair to a light brown that looks like highlights. I've been using it for 2 years.

Works great for daily washing of hair

I bought this for darkening my gray hair. In 4 uses, my hair is literally breaking off like I have never experienced before. My hair is fine and also prone to breakage. I have been using natural bar shampoo for over a year now and have seen my breakage stop and hair become fuller and grow longer. In just 4 uses of this shampoo, I am set back, not only set back, but my hair has not been this damaged in years. I threw it in the trash and wanted to just warn others about...if your hair is fine and prone to breakage, do not use this product for even one wash. I starting see handfuls of hair in the shower drain on the first use. I am so disappointed with the damage done and am sure it will take another year for my hair to fully recover.

A round bar of solid shampoo isn’t what I’d ordinarily think of when I think of shampoo. But why not? Plastic bottles of shampoo contain the cleaning agents, fragrance, etc mixed with lots of water in a big wasteful bottle.So, I’ve tried this bar shampoo and I love the scent! It smells like a summer day at the beach. It’s a warm scent and another reviewer nailed it. Kind of like popcorn balls.It lathers well and cleaned my hair well. After drying, my hair feels soft and silky smooth. I don’t know if it prevents hair loss or promotes growth because it’s really too soon to evaluate that.

Its super good..its for my husband..que love it. Because he have a several losing hair..now its grpwing

Just started using it, but the smell is awful! Not sure I can keep the bar in the bathroom! I may have to use it on the sink in the garage! Will keep you posted...

This bar sudses up well and leaves my hair squeaky clean.It has restored my natural curls and managability. I cannot attest to the fragrance as I lost my sense of smell with my last bout of covid.I have tried a number of bar soaps and this one works the best so far.

I researched the product discovered that to darken hair you wash rinse then wash again a leave it massaged into scalp for 3-5 mins. If you want it to darken it will take at least 3 months of use. It lathers fantastic- I have thick long hair and it worked great- I will add to review after 3 months. My scalp does not itch or feel dry- hair feels healthy after one time of using it. The smell dissipates quickly from hair. ( I was not fond of the smell) one thing it was supposed to be two but only one bar came.3 months and no real change in color. Shampoo lather well but I have developed an itchy scalp smell once I have several allergies I have decided to discontinue using it.
