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

Right is before; left is after 12 weeks. This product is like a miracle - an answer to prayer. After 3 months, I’m getting compliments on my hair now and have recommended to others. As a senior, my hair had became so thin and white. I felt almost bald on top and at my temples. I was losing it in drain every time I shampooed. I began looking for natural solution to hair loss and dying it. This worked. At 2 weeks I could already see fuzzy new growth. Your hair will look fuzzy for awhile. Then I noticed there was a lot more dark hairs coming in (my hair had almost turned all-white). In the before, you can see about 3 inches of growth after I had died it ash brown. I only have a little white left in front that is slowing darkening. No more hairs in the drain. Like all natural remedies, you have to be consistent and patient. Our hair only grows 1/2 inch a month. Here is how I used it: wet hair and shampoo bar, rub gently over my part, temples and remainder of hair. A little gives you lots of later. Massage into scalp for about a minute. Leave lather piled on hair for about 5 minutes, then rinse and condition as normal. I do it at beginning of shower so by time I’m done it is at least 5 minutes: Smell: It smells herby but goes away as soon as hair dries. How Long does bar last: I let it dry out after use so did not get mushy and one bar lasts about 4 weeks using 3 times a week. Then breaks up into pieces but I just mushed up the broken pieces from a couple bars and used them for another few weeks. Cheaper than hair dye and regular shampoo. Highly recommend it. Take a before pic because changes are subtle in the beginning but look after 3 months. Amazing!

Do not waste your money.

It works great for removing wax and pomade from hair before shampooing. It doesn't get rid of the Grey hair, also has a funky plastic smell.

It took about 5 times before I noticed any difference, so don't get discouraged at first. Now, with 2 or three shampooing a week I can keep my color! I have found that it works best if I apply at the beginning of my shower and then rinse with warm not hot water.In case you haven't used a shampoo bar before the best way is to lather between your hands, (put the bar back someplace where shower water won't hit it and wash it down the drain) and then apply to hair like you would liquid shampoo.

This product does not work. Fades after a couple of hours. Not what I expected. How about a refund!!!

Does it darken....nope. Regardless, it is natural, lasted a long time as I bought this one last year in August and it has almost to nothing. I use this bar by my sink if I only need to wash my hair, so I use it about +2 times every week to this day. I would get Head and Shoulders, and this does a far better job. I felt like the name bands might of been causing hair loss. So I felt this bar was well worth the time to recap. So, points on Hair Health, cheap, and Longevity

Has a bad smell and does not work

My hair feels soft and healthy. It lasts a long time. I been using the bar for several months and the bar is still going strong. I bet it lasts a year! Oh another thing my scalp feels good. Regular shampoo would make my scalp itch so this product is amazing it is easy to use.I only have to shampoo 1-2 times a week and my hair looks clean longer.
