Rishiri Color Konbu 天然洗发水 200ml - 4 款

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!

You need to consistently use it for 4 or 5 times to see the difference. I kept it on for over half hour before wash it off and put on conditioner. I can tell it's all natural since there's no developer. Just need to be patient and you don't need to worry about the unknown chemicals.

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.

This product works naturally to dye my hair. It doesn't change color after the first few washes. I was almost losing faith, but I still use it for curiosity. Miraculously, after the 7th wash, I notice my white hair has decreased significantly. On my 10th wash, my hair is almost black. Love it, will buy more again.

Repeat buyer. It may not be effective coloring completely but it covers gray somewhat and it is gentle on your scalp.
