## Description

desertcart.com : COSMTEK Black Hair Dye Shampoo, Semi-Permanent Hair Color Shampoo for Women and Men, 3 in 1, Grey Coverage 400ml/ 13.5 fl.oz : Beauty & Personal Care

Review: Great Coverage & Easy to Use (Annual Go-To!) - I’ve been buying this Semi-Permanent Black Hair Dye Shampoo every year because it truly works. It is one of the easiest ways to get my hair fully black without the mess of traditional kits. The Pros: Full Coverage: It never leaves patches; my hair comes out a deep, consistent black every single time. Convenience: Using it like a regular shampoo makes the process much faster and less intimidating. Longevity: For a semi-permanent product, the color holds up very well over time. The One Downside: The only annoying part is that it tints skin very easily. If it touches your forehead or scalp, it can be quite stubborn to wash off. I usually have to use a bit of alcohol and scrub fairly hard to remove the staining from my skin, so I definitely recommend using a barrier cream (like Vaseline) around your hairline before starting! High-quality color that lasts, just be careful with the application to save yourself the scrubbing later.
Review: This is really PERMANENT! - 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.

### ⭐⭐⭐⭐ A huge time-saver compared to traditional box dye, but beware of shower splatters!
*by T***N on March 6, 2026*

I usually rely on traditional, heavy-duty nourishing cream box dyes to handle my stubborn grays, but the whole mixing, sectioning, and waiting process can be exhausting. I picked up this Black Hair Dye Shampoo looking for a quicker, lower-maintenance alternative for touch-ups, and it genuinely surprised me. Here is how it actually performs: Ease of Use: This is where the product completely shines. Pumping it out and working it through your hair like a regular shampoo is infinitely faster than precisely painting on a traditional dye. It cuts the prep and application time down drastically. Coverage: For a semi-permanent shampoo, the coverage is remarkably solid. It darkened my lighter strands very effectively and blended them into a natural-looking black finish, rather than an inky, flat color. The Scent: Because it utilizes herbal ingredients, it lacks that overpowering, eye-watering ammonia smell that usually lingers in the bathroom after coloring your hair. The Drawbacks: Just because it says 'shampoo' doesn't mean it won't stain like a traditional dye. You absolutely still need to wear gloves (which it thankfully includes), and you have to be very careful not to let the dark lather splatter onto your shower tiles or grout, as it will leave stains if you don't rinse it away immediately. Verdict: If you need a fast, low-effort way to cover grays without the hassle of a full chemical processing session, this is a highly convenient option. Just treat it with the same caution regarding stains as you would any other dye!
