## Customer Reviews

### ⭐⭐⭐⭐⭐ Very good. Made dye my hair a lot easier.
*by B***N on July 22, 2025*

This product I really like so far. I was a big just for men guy. But just for men wouldn’t just target hair. It would dye everything, clothes, sink, bathtub, countertop, floor, skin, and etc. Instead of calling it just for men it should be called just for everything. with this product, it went straight from my hair and that’s it no cleaning in the sink or the countertops. Because at the end, it did what it was supposed to do. It just dye your hair.

### ⭐⭐⭐⭐⭐ This is really PERMANENT!
*by S***V on March 31, 2023*

I've been using COSMTEK Black Hair Dye Shampoo for many months now, and I'm really happy with the results. My hair is now completely black, and the color has stayed true even after multiple washes. I also like that the shampoo is ammonia-free and contains herbal ingredients, so it's gentle on my hair and scalp. Overall, I highly recommend COSMTEK Black Hair Dye Shampoo to anyone looking for a natural and effective way to cover gray hair.Here are some of the things I like about this product:It's easy to use. Just apply it like regular shampoo and leave it on for 15-20 minutes.It covers gray hair completely. I have a lot of gray hair, and this shampoo covered it all without any streaks or unevenness.The color lasts. I've been using the shampoo for about a month now, and the color has stayed true even after multiple washes.It's ammonia-free and contains herbal ingredients. This means it's gentle on my hair and scalp.One thing to keep in mind is that this dye penetrates all layers of hair, so it is not washable or lightable. This means that if you decide you don't want black hair, you will need to wait while your hair will grow up. You can not even bleach to remove the color.Another thing to keep in mind is that this dye is very strong and can stain skin and surfaces. It is important to wear gloves when applying the shampoo and to wash your hands and any surfaces that come into contact with the dye immediately.Overall, I'm very happy with COSMTEK Black Hair Dye Shampoo. It's a great product for covering gray hair, and I highly recommend it.

### ⭐⭐⭐⭐ Works as instructed - good value for the price
*by K***N on August 11, 2023*

I had tried similar products in the past and had returned it after the first use. I was skeptical with this one and after using it for 3 weeks and 3 uses, I can share that it does what it’s supposed to do.What I like about it:Big size!ReusableGives that dark/black tone to my hairEasy to useDoes not stain skin if you wipe it off right awayWhat I don’t like about this and similar products is the color-fades after a couple of days - at least for me. You can see the dark brown shade to it after 3-4 days, and after a week it turns to light brown on the hair on my sides, then on the top, where it is normally darker, it turns to a mid-brown color. At about 7-8 days my hair looks darkish brown which I am not comfortable with since I have had black hair all my life - until it started turning grey. ^_^Also after the first use I rinsed it off as instructed but it my scalp really itchy, specially on the back. On the second use I switched my shower head to jet and really rinsed off the product well, my scalp was not so itchy as the first time, but still a bit itchy. This use I followed the same procedure and again a bit itchy on the back, not on top. I would also suggest using a dark colored towel since this does stain towels, I have a dark turquoise towel and you can see the grey/black cloud where I dried my hair.I tried it on my beard which is 80% grey/white and although this does work on my beard, the color fades off after 3-4 days, leaving a light brown tint.Overall I would recommend it, it works better than a lot of other products.
