Review: easy it is to use - I love how easy it is to use. It covers gray hair perfectly and keeps a deep, shiny black color for several weeks, even after multiple washes. What really surprised me is that it does not stain the skin, so I no longer have to scrub to remove dye residue. Since I found it, I said goodbye to boxed drugstore dyes. The bottle is quite large, so it lasts a long time and you don’t have to keep buying a new one, which makes it very cost-effective. I feel like my hair has improved 1000/100. I highly recommend it. I hadn’t found such an effective product in a long time. I loved it!
Review: Long lasting, no fade, black hair dye - So the first time I bought and used this, mixing the two parts (as you should) would create a sulfur-y smell that stunk pretty bad, but did go away. The second bottle I bought, when I mix the parts now gives off a strong nice herbal smell. Not sure what changed but definitely a win! I think this is mainly meant to cover grey hairs for people who already have black hair. But I use it to dye my dirty blonde hair black. I go an extra mile, and mix the shampoo dye in a dish and brush apply the dye directly to my roots, rather than rubbing it in my hair exactly like a shampoo (I have VERY long hair). It works FANTASTICALLY. Leave it on for about 20+ minutes and my roots are all perfect black. I never have to redye the ends of my hair, the black color STAYS, no fading. The dye WILL stain if you get it on things like old laminate, porcelain... I obviously did not test every surface in my house for what would or wouldn't. So ere on the side of caution. (I did find that the brand of contact paper I put over the counter COULDN'T be stained, which was great) My hair has stayed soft and silky. I apply after a few days of unwashed hair so the natural oils help protect, and lightly condition right after washing out the dye (dye rinsed off in water does not stain unless left standing) I full dye my roots about every 2-3 weeks, using several pumps of the bottle, and it lasts me 5+ months. Which sure as heck beats spending $200 at the hair salon. 10/10 fantastic product!

## Questions & Answers

**Q: What will it do to African American hair**
A: I'm not African American but I have coarse hair.  It works good on my hair.  I use it on the hair on my chest too, and it works good there as well.  I would imagine that if you left it on for and extra minute or two,  it would work well.  
I have noticed that if you don't use it at least once a week and you live in a sunny area,  it acts like the product called "sun-in" and it will start turning the tips of hair to a light brown or blonde but even that has a natural look.

**Q: What is the country of origin?**
A: USA

**Q: Does this dark brown hair dye shampoo have peroxide or ammonia?**
A: Ammonium Hydroxide and Hydrogen Peroxide are listed in the product ingredients.

**Q: Will this product stain your skin like permanent hair color? Do you have to wear gloves while applying on my hair?**
A: Hello, yes it did stain my already stained hair color tee shirt and it stained the skin where some got on my wrists but that washed off easily. 
Please wear gloves when using it. The kit contains gloves and a pullover plastic cover for your clothes but I am a sloppy hair colorer.  I will say that I love it tho.  
I have used it twice so far, the first time it did not cover all the grey, but I feel it’s because I needed to learn how to use properly and leave it on a bit longer. 
 The second time it covered the grey perfectly.  This will be my new go to for hair color.  Hope this answers your question.

### ⭐⭐⭐⭐⭐ BUY IT!
*by H***A on May 23, 2024*

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.
