Climate Pledge Friendly
I read through all the reviews and was skeptical it would work but bought it anyway. It delivered yesterday. Immediately put it in. Back story: I've been coloring my hair the darkest brown (basically black without the blue hue) for the last 20 years. At this stage of life, the grays are starting to show in 3 days. By two weeks, have a straight line almost 1/4 inch thick of solid gray line of root growth throughout most of my head (at least what I can see). Yesterday, I was at the two week mark. I applied a generous amount onto dry hair. Massaged it into my roots for 3 to 4 minutes (could of been 5). Let it sit for 25 mins. Took a shower. In the shower, lathered and scrubbed for a few minutes. Washed out. Conditioned as usual. Results: Whoa, it completely covered my roots. Things I noticed that you should know.
1) The smell was really not bad especially not as bad as many reviewers have stated. This smells like fresh flowers compared to actual hair dye. Seriously, I think it actually smells pretty good.
2) A drop managed to fall on my white sink. Noticed it 25 minutes later when I came back to shower.
Washed right off without leaving a stain.
3) White tile shower is not stained with black dye (not even a little)
4) I DO NOT HAVE A STAINED FOREHEAD EDGE from hair dye (this is huge for me)
I don't know what it will look like in a few days. If the color will wash off or lighten. But, honestly, I don't care if it does. This was so easy to do with no mess. I would do it every 3 days if need be and wouldn't feel like a chore as coloring with hair dye does. 10 10 recommended this to anyone with black hair. Total game changer!
Update as of September 2024:
Still love it! I’m on my 2nd bottle. Use it every 1.5 to 2.5 weeks. Covers all my grays and doesn’t fade. I even got a compliment on my color the other day from a hair stylist. She said my color is gorgeous and she was so surprised that the ends of my hair weren’t faded. She even asked if I went outside at all during the summer because she couldn’t believe it lol. I only color my roots but guess when rinsing out it gives a little extra love to the ends. The only change I made is that I don’t message it in as much. Just apply and rub it in at that moment. Move to the next section. Repeat. Do my hairline again. Wait 25 to 30 mins. Shower. It does dry my hair a bit which also happened when I used regular dye so it’s no biggie. Just skip washing my hair an extra day.

Pleasantly surprised!
I bought this a while ago but I've been putting off trying it because I was nervous. No reason to be AT ALL. I have a side shave (if you couldn't tell lol) and so I dyed my hair prior to touching up my side shave and I was shocked at how well it covered all the way to the skin! The other side has a few stray grays but I think that's user error. I was still nervous because I was worried about my skin staining (i put ZERO protection along my hairline but it all came off beautifully. I'm looking forward to seeing how long this lasts and the long term effects it will have on my hair health. As it stands, I'm incredibly pleased and will be buying a box of gloves so I can keep using this product- it only had one pair in the box and the bottle is good for PLENTY of applications. I might try as someone else suggested and using a brush to apply it just to my roots next time to save product. We'll see how it goes. Very happy so far!
