Color: black
This dye shampoo delivers impressive results. It covers grays evenly, leaves hair feeling soft, and doesn’t have a harsh chemical smell. (well al ittle) Application is simple — just use it like regular beard shampoo. Watch the skin... wipe as needed... wait 20min... The color looks natural and lasts well. Great value for a large bottle.

Color: dark brown
Excellent product especially for guys who are looking for a color that gives 100 percent grey coverage who have a long beard. This big bottle lasts a long time because the product ingredient's are pumped out the bottle together but separately. So you are mixing whatever you pump from the bottle in your hands as it is dispensed from the bottle. The product in the bottle stays fresh till you are ready to use it again and again. I've already gotten 4 uses out of it already and I will say I'll get one more. This is from retouching the roots once a month. The product does not burn my face off like other store bought color does! It doesn't even stain your skin bad either. No more trying to scrub the stained skin off your face afterwards. (Do wear the gloves though when applying because it does stain hands.) It's also not as harsh on the hair as others I've used. It rinses out easily since it is mixed with shampoo. All you have to do is condition afterwards. The color lasts with very minimal fading. I absolutely love this product. This review is from using Dark Brown once a month. It's so easy to use and you get a lot of uses out of one bottle for the cost.

Love this product. My mom bought and loved it so I thought I would try. At this time only used once and been almost 2 months. Ready to use again mainly around my face. Used gloves and is a little slippery when rubbing in your hands before putting on your hair, but like better than using hair coloring. Shampoo seems to work at this time. Hair was soft.

Color: dark brown
I like this one. It works better than some of its competitors which is fantastic but that also means that I don’t have to choose a darker shade to get the right color. I’ll definitely buy again but in a shade or two lighter than the first one I bought

Color: black
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.

Color: chestnut brown
After years of expensive salon coloring and my grays peeking through after just 3 weeks, this has completely changed my routine. I’ve been using it for over a year now and only need to color every 5–6 weeks. It’s so convenient and easy to use at home — just don’t accidentally color your tile grout like I did. I originally started with Black color, but it was way too dark for me and took forever to fade out. I switched to Dark Brown and that has been perfect. One thing to know: the Chestnut Brown does NOT cover grays. My roots turned a yellowish brown and it was a disaster. Online pictures and on the front of the box it looks like part of the same gray coverage line, but once the box arrives, the side actually says it’s not for gray coverage. I’m sticking with Dark Brown — my hair feels healthy, shiny, and the application is incredibly easy. Definitely my go-to now.

Color: dark brown
I used this last night while the application was very easy, the way this made my hair feel after washing it out made me throw it away. My hair was SO DRY and stringy. I had to condition it heavily. Today it still feels quite dry. I'm not willing to do that to my hair every time I use this. When you pump the product out of the bottle, one side is clear and the other is cream, so I guess you're sort of mixing the product in your hand and then applying. As for the dye job itself, it seems to have worked as advertised. My greys are covered and the color seems even. The color in the photo of the dark brown is NOT ACCURATE. I was looking for something like in the pictures a brown. Certainly not almost BLACK - as in I can see some brown highlights in the light. I'll be washing my hair a bit extra to try to get this out or at least fade a bit.

I hardly ever take the time to write reviews, but finding this product has genuinely been a life hack for me. I’m a natural redhead who dyes my hair black, and my roots start showing about every two weeks and it appears as though I’m balding. When that happens, it makes a huge difference in my appearance and confidence. Because I need touch-ups so often, going to a professional salon just is not realistic or manageable for me. This product has been truly transformative as a quick, easy solution and even a fix between colorings which I find to only be necessary once or twice a year because of this product. For my hair (and even my blonde eyebrows) it gives me exactly the touch-up I need and makes maintenance so much easier. I sincerely hope this product stays on the market, because with how much upkeep it takes to go from red to black, I would be lost without it.
