cosmpro Black Hair Dye Shampoo Color Shampoo for Gray Coverage | Instant Hair Color For Women Men Easy to Use

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.

I didn't believe in the hype but I can honestly say I was skeptical about getting this product. I enjoy using this because it doesn't leave my hair in a brittle state, it lasts for about 4 weeks, my hair has a healthy shine. My hair patterns are wavy, and curly hair. I do leave the solution in for about 45 minutes-1 hour

Product came well packaged, is quite easy and simple to use, just follow the few instructions which come on the package, it works quite well, and it lasts just as if getting a hair tint at any saloon. I highly recommend this new and innovative product, also the size is great, and presentation is outstanding, leaves your heair moist and shinny, abd free of scalp irritation.

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.

This product is amazing. It covers not only roots you can see, but the whole she-bang - the parts you can't see, like the back of your head. After years of using standard box dyes for roots, I'm thrilled to have found this product, which I find much better, for its full coverage. What you may not glean from the other reviews: 1. It's super-duper messy. The dye gets everywhere - on you and your surroundings. What I learned: To prevent stains on you, put Vaseline or a blocker cream around your hairline and ears. To prevent them on your home, cover all nearby surfaces (and then some). If you'll be showering the dye off and have a shower curtain, don't be surprised that it will get stained. 2. Use the little clear plastic dickey that comes with the dye to cover your shoulders and upper chest (it's like a short version of a dry cleaner's garment cover, but with elastic around the neck). But remember to smear Vaseline on your arms, chest, and neck to prevent serious staining. 3. The color coverage is excellent. The only thing it doesn't cover are those stubborn grays around the hairline. But what really does? 4. The dye comes off, visibly, every time you wash your hair. It also comes off on your towels and can drip onto your bathrobe. I recently traveled and brought my own towels - black ones, like they use at a salon - so as not to ruin my host's towels. 5. Some people reported allergic reactions. That will always vary from person to person. I'm okay on that front, but do find the chemicals a bit irritating just on day one. In summary, I find this product messy, but effective. A product improvement would be for the manufacturer to offer tips or product (i.e., better than Vaseline, which only works partly) to prevent stains - and more than two of those dickeys in the box.

Uniform shape and the dark brown color was very natural. In addition, it is easy to apply because it works like a normal shampoo. My hair was soft and shiny. I'll buy it again.

i'm finally at that stage in my life where it was time to make that decision. there were too many grays to pluck, but they were only sitting around my hairline with a few strays across the rest of my scalp. i'd never colored my hair before, so did i want to take the dive and drop 2 or 3 hundred at a salon and get stuck in that cycle? did i want to do the drugstore full head permanent box dye and risk it not looking natural? i sat on the fence for months as more grays started to appear and soon i was going to have the bride of frankenstein pattern happening (which honestly is not terrible)...but had some real decisions to make here!! then my sister in law told me she tried the polar hair dye shampoo and had good results from that which softened me up towards considering trying it. at the time when i was ready to bite the bullet and buy it, the polar black dye version was not available on amazon...maybe they were out? in searching for it, i came across this product (and several others that are similar to it). i chose this one because the reviews were good enough and there were enough reviews that i figured a good amount of them had to be legit and not ai bot-generated. when i received it, i was conservative and followed the instructions by doing a patch test to ensure i didn't have any allergic reaction to it. after that i did my first treatment. using gloves it came with on dry hair when applying, i literally only used about 2-3 pumps of the dye shampoo to cover my hairline (i have medium-long hair) and only left it for 8 minutes. (the instructions recommended 20 mins but after reading other reviews here, i started with 8). the shampoo smelled pretty good and not overwhelming of chemical scent like box dyes and i was super pleased with the color. it looked very natural - though unfortunately it washed out in about 2 weeks. i did it over the sink and there were no stains or anything which i was also pleased with. after those 2 weeks, i did another treatment and decided that time to leave it in for 15 minutes. from there, i went straight to the shower and rinsed it out there and continued with the rest of my shower (i didn't shampoo, just rinsed and conditioned). the results after that were perfect. it looked perfectly natural and blended in with the rest of my hair and the best thing - it now has lasted over a month and i'm just starting to see it slowly fade and wash out. it's not like permanent dyes where you can clearly see the new hair growth and a defined line at the roots as new hair grows out. the color just fades gradually and any grays that start to appear look very natural. its been over a month now and i am going to soon re-apply it to restore the color once again. would i buy it again? a resounding yes!...though this bottle is huge and since you can dispense just what you need each time, i can see this lasting way more than a year, maybe two, so i won't need to buy more any time soon!

Great hair dye with long-lasting color if you take good care of it. The only downside is that it can stain your hands, but wearing two pairs of gloves solves the problem.
