COSMTEK Dark Brown Hair Dye Shampoo for Gray Hair, Instant Natural Hair Color Shampoo for Women & Man, 3-In-1 & Semi-Permanent, Herbal Ingredients & Ammonia-Free, Fast Acting and Long Lasting

I originally bought this in an emergency to cover up my grays before seeing my sister and I was so shocked at how amazing the color was and hair looked . Use good conditioner or gloss now and again but people loved it so much I stayed dark brunette a while My hair never got brittle . Fast- forward I am now highlighted blonde and this is what my highschool daughter uses to color her hair. Her hair is gorgeous . Amazing product .

This shampoo covers gray hair very well and lasts at least 3 weeks.

I love this product! I had so many white hairs growing and I was tired of plucking them.This shampoo is easy to use; but make sure to wash your hair first to remove any product build-up on your hair and scalp.After your hair is dry, apply this product on your hair . The instructions say to use your hands, but I used a brush to make sure it would color the hair from the root.A shoulder cover and gloves are included. I washed my hair 20 minutes later and, voila! All white hair was colored.My hair was very dry after, so I used a deep conditioner cream and let it sit overnight. Washed it off in the morning and my hair was fine again.

Very easy and take 20 minute to work cover my grey hair . Save money for salon .

I have been trying to grow out old highlights and my hair looks terrible. My natural hair is dark brown and gray. I had lowlights done professionally and they washed out so quick. I live in Hawaii and the sun is so strong here. I also tried a brown shampoo but it made my hair look more green. I found this and decided to give it a try. I absolutely love it! Only left it on for about 7 min and even after numerous washes, the color is staying on well. I highly recommend!

I cannot believe ammonia is one of the ingredients in this shampoo. This can damage, dry your hair and skin and for sure it did when I put it on my hair was so dry and even lost my wavy hair and my scalp was so dry. This shampoo is better in the trash.

El shampoo no trae color 😖 no salió bien, no pinta!!😔

Not bad, cover gray hair. But I used two times now and I lost too much hair both times and left my hair super dry so kinda worried me. I’m gonna stop using this.
