Color Treatment for Gray Coverage – Subtle, Gradual Semi-Permanent Hair Color – Hydrating, Sulfate-Free, Ammonia-Free, Vegan Color Depositing with 31 Botanical Extracts (Black)

I have read about this product in Japanese cosmetics review site and the product was highly rated. So I wanted to give it a try.I do have about 75% grey. I used to color at home with usual drugstore bought hair color, but was starting to be very concerned with hair damages.This product will not penetrate your skin like the usual hair color, so cleanup is quite easy.User posted pointers I've got from the Japanese sites were following:1) Use on clean dry hair2) For those with more than 50% grey, leave the product on for more than 20 min. (I did 30 min.)3) Use plastic wrap or plastic shower cap (you need to raise the temp. in order for color to settle)4) Use liberal amounts around the hair lines5) After rinsing, make sure to hot air blow dry (also help with settle in the color)6) Use non-sulfur shampoo to keep the colorFor first timer, you may need to repeat the process 2-3 times to get perfect grey coverage.I'm quite happy with this product and definitely buy again.

Update: I've used it a couple more times and I think it works better the more you use it. I am able to go two weeks before I need to reapply and for me that's worth the extra time investment given that it is odor free and does not make my scalp itch like salon dye. Also it looks more natural as it fades away than the stark contrast of having gray roots.Original review:Works ok,doesn't totally cover, just makes it less noticeable. Also washes out sooner than I expected, after 2 or 3 washes (I wash every 2 days with sulfate free shampoo). I followed the instructions exactly, which takes more time than I thought it would. You have to totally wash your hair, wait for it to dry, apply the stuff, wait up to 1 hr, then rinse it out and blow dry your hair. Not a lot of work, but a lot of time involved, not really worth it for something that washes out so quickly. On the plus side no odor whatsoever.

I am growing out my gray and I have been using this as I transition. I use it about every two weeks, leaving it on for ten minutes before rinsing and blow drying. It is working for me. It covers the gray to the degree I want it to--meaning, I don't mind some gray showing, I just don't like the "line" caused by using permanent hair color in the past. I have about one full year to go until everything is grown out. I will update later. I have brown hair that tends to turn brassy. I use the dark brown and it looks like I have highlights. I am happy so far.

Pretty nice hair dye! I used to use hena to die my hair. But it was pretty messy. This product makes my hair dying much simpler and faster than before.

does not last, especially if u have to moisturize your hair regularly

I bought this from The Grommet. I think the reason people aren't happy with it is that they are using too much or washing it out. You DON'T wash it out until the next time you wash your hair and you don't need much at all. I really like it and generally have to touch up my roots about every 10 days. Instead I can just paint this on around my part and around my face. It dries quickly and I'm good to go. The creator says you can use hair color over this and don't have to wash it out when ready to do that. I have used it 3 times and colored with my usual product over this. I am really so happy that I can postpone root touch up. Really happy with this. Wish it were not quite so expensive but the convenience seems worth it, at least for me.

My greys still showed even after using it three times. I gave up.

have used it 3 times. does not cover the grey. do not waste your money.
