RISHIRIColoring Shampoo (Black)

It really works as expected! I would say - great quality and dye my hair with natural materials without harm to body. I am in late 40s with 3/4 of my hair grey.One know-how: if your hair is oily and you don't wash your hair everyday, you may wash your hair with a normal shampoo the first time; then wash your hair with this hair color product the second time. You will get a good effect. I love it; thank you!

How long does it take to see the result? No explanation is cited. I used it everyday for a week. No effect so far

I used similar products in the past and had great results. This particular one didn't come with directions. I wasn't sure if I should wait 5 min after applying the product to my hair( I should have).That is why I give 4 not 5.,and hope for better instructions next time.

By the time I used up the first bottle, my gray hairs were less noticeable. Another good thing is that my hair loss during shampooing has been reduced to less than half. And my head does not smell bad on a daily basis.

Took a while to see color

Perfect for people who don't like the smell of ammonia based dye. Takes a few washes to start to see the color but it's as simple as washing your hair.

Not what I wanted. The liquid is so dark and messed up my towel even after I rinsed my hair well. i used 7 days straight, but I still have greys. Maybe, this is for people who can spend hours during her shower.... Sory, I am not the one. Since I opened and used this product, I would not return it. But, I will not buy it again. Thanks....

Not only this shampoo but I also use Rishiri conditioner.Unfortunately I do not see any improvement.I am not recommend this products to my friends.
