He wanted something quick and easy to cover his grays without the whole dye kit drama, and this shampoo does the trick perfectly. It’s super simple to use: rub it in like regular shampoo, wait about 15–20 minutes, rinse, and boom, black hair. It covers grays well and looks natural, not patchy or fake. The scent is light and fades fast, and his hair feels soft afterward, not dry or stiff. The color lasts a couple of weeks before fading to a dark brown, so we just reapply when needed. Overall, he loves it, and I love that he’s happy with how it looks. Keeping this one stocked. Review: - HONEST REVIEW - - I was VERY skeptical, but after reading reviews you can't go wrong with the majority. I wasn't expecting results TBH, i first tried it, left it in but forgot to use a timer, i think it was only not even 10min then I washed it off, and i still had greys. I was upset, but then i washed my face & dried it well and applied it again. It comes out clear and a dye all in one pump. WASH THROUGHLY! I left it in this time and i used a 20 min timer. By the 12-13th min it started to burn/tingle a lil bit. I left it in a little longer, washed off and that's what you see. GREAT product. Not sure how long it last, but we will see. Edit: i decided to go a different route and go dark brown. The black looks good, however it was TOO black! I kind of threw off the balance of my look. Going for Dark brown and i will do another separate review ## Features - 【Formula Upgrade】The color depositing shampoo has been optimized with a formula. You can see the full formula table of the product, so you can use it with peace of mind. - 【No Frizz】 We added Argan Oil, Olive Oil and Turmeric to the semi permanent hair color.

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! Reusable Gives that dark/black tone to my hair Easy to use Does not stain skin if you wipe it off right away What 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. ## Frequently Bought Together - Black Hair Dye Shampoo, Semi-Permanent Hair Color Shampoo for Women and Men, Herbal Ingredients and No Ammonia, 3 in 1-100% Grey Coverage 400ml/ 13.5 fl.oz - KAISASA Black Hair Dye Shampoo 3 in 1，Argan Natural Herbal Hair Color Shampoo Covers Gray Hair for Women and Men (16.9 fl.oz Black) --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.vu/products/455929399-black-hair-dye-shampoo-semi-permanent-hair-color-shampoo-women](https://www.desertcart.vu/products/455929399-black-hair-dye-shampoo-semi-permanent-hair-color-shampoo-women) --- *Product available on Desertcart Vanuatu* *Store origin: VU* *Last updated: 2026-05-10*
