cosmpro Black Hair Dye Shampoo 3 in 1 for Women/Men for Gray Coverage Instant Hair Color Shampoo Semi Permanent Champu Para Cana

I tried this hair dye shampoo two days ago and so far I’m really happy with the results. The color came out exactly as described — a nice deep black that covered my hair evenly. My hair looks shiny and feels soft after using it, which I liked because some hair dyes can leave hair feeling dry. The application was very simple. It works like a regular shampoo: you apply it to the hair, leave it on for about 15–20 minutes, and then rinse. I appreciated how convenient that was compared to traditional hair dyes that require multiple steps and mixing. I did have a small delivery issue at first where my order seemed delayed, and a replacement was sent. The original package ended up arriving afterward, but I returned the extra one without any problem. Aside from that shipping confusion, the product itself worked very well. After two days, the color still looks rich and natural, and I would definitely consider using this again in the future. If you’re looking for a quick and easy way to refresh your hair color at home, this shampoo is a good option.

Excellent product. It colors the hair very well, and the color lasts. I ordered dark brown, and the shade is great.

This shampoo is too good to cover gray hair, with its use I have a breath of hair dyes since this product does its job excellently and lasts a long time so that gray hair reappears again

First time use was pretty easy, not a fan of the smell.

Love this so easy and less expensive

I bought this two weeks ago, was very skeptical to try after the warning about allergies even though I have no known allergies. I did the test as recommended but not behind my ear but on my upper arm because I wanted to make sure I can see the results of the test. Did not leave it for six hours as recommended got frustrated was afraid to use so I put in the trash last night….This morning I decide to remove it from the trash and use the dye…..it really really works great….great coverage of gray hair I am sorry I did not take a before picture….awesome and easy to use……next time will take a before and after pic. My hairline grows out really fast, I am over 70 so this is to be expected. I only need to color hairline. Highly effective.

UPDATE.Im in between 4 and 5 stars. I washed my hair and the color did not fade. I did notice that my hair got the chemical smell. I used my normal shampoo. It still smells like the color shampoo. That's why I'm in between stars. Anyway so after 4 days I think I washed my hair. In those days my hair did not get greasy(which it usually happens) it was not dry just my ends but that's on me damaging my hair for years. Anyway I recommend it. I just didn't like the smell after I washed it but I think some dry shampoo can cover it up. I will keep it at 5. If all of a sudden I start going bald I will let you know My hair is extremely dry,doesn't hold moisture and extremely frizzy. Before I used the shampoo I had about an in of my hair growin out which is grey hair. On the tips of my hair in the front I had discoloration from a previous hair dye. For many years I used hena and the reason I changed to this shampoo is because how my hair was just not wanting it anymore. I really just wanted to shave it off and start fresh. Moving on to product. The gloves it comes with trash them. Shampoo was getting into them. The shampoo does smell like chemical which doesn't really bother me. Lather it up and I did split into sections. I left it for 30 minutes just because my hair is stubborn. I rinsed it, did not shampoo since the box says don't wash off for 6 hrs I'm thinking it means my personal shampoo. Moving on extremely easy to use less mess. It covered my greys and the discoloration I had at the ends. My hair does feel soft. When I dried it no frizz. I hope it last long but there's enough for touch ups. You can still see how my hair is dry but it does feel different. I will definitely update to see how long it lasted and if the moisture of my hair changes. BTW after drying it it does have a chemo cal smell too but it's faint.

At first, it works really well, especially if you wash your hair right before heading out. With each wash, I noticed the color improving and looking more vibrant. I also appreciate that it’s made with natural ingredients, so it feels gentle on my fathers hair. Overall, a reliable product that actually delivers results over time.
