I used to bleach my roots every 8 weeks or so in order to have bright fashion colours ( pink/ purple ) , and with doing this a lot of hair at the nape of my neck and around my hairline had broken off. Since having ditched the bleach and the broken parts now growing back in nicely my hair was starting to look a bit drab as I have lots of white hairs at the root ( about 4 inches worth ). I was just using my usual semi permanent colours, but after about 3 washes the white hair was popping through again and sticking out like a sore thumb. I spent a good deal of time looking for purple colours on desertcart that cover grey/white hair. And I came across this one which is permanent. It's not going to do as much damage to my hair as bleach will as it is a conditioning based permanent dye so I'm so happy that I can now carry on having purple 💜 hair without struggling on how I'm going to cover my white hair and risking more damage to my hair. This hair dye is absolutely amazing, it is thick in consistency as it is a conditioning based permanent hair dye so trying to squeeze it from the bottle once mixed is hard work so next time I will put it in a bowl mix it and use a brush. The colour came out even all over and my hair didn't feel dry after so I'm happy that I am not doing damage to my hair. Highly , highly recommend this dye it is the best!. Update after having washed it 3 times , the colour has faded but it's still really vibrant and such a beautiful colour. I did find that the colour faded a lot more quickly than other permanent hair dyes do , as the vibrancy normally lasts a lot longer with other brands , but it faded to a nice lilac colour after about 6 washes , I wash my hair once a week for reference, so if you wash your hair more often then the colour will fade a lot quicker. Review: Bright purple hair 😍 - This worked better then I thought. I had bleached my hair the same day and then use this and I have bright purple hair which doesn't quite show in the picture. It's a bit to bright for my liking but I am pleased overall Update, after a few washes my hair went pinky purple and after nearly a month a dirty pink colour but I still had lots of compliments even with the faded look. ## Features - Hair dye for dark hair.

It's a bit to bright for my liking but I am pleased overall Update, after a few washes my hair went pinky purple and after nearly a month a dirty pink colour but I still had lots of compliments even with the faded look. ### ⭐ ONLY LASTS A COUPLE OF WASHES! *by J***E on 18 December 2022* I purchased two of these at the same time,but sadly won't be buying anymore. The colour turns out to be l9vely and vibrant and I loved it when i'd first used it. Unfortunately it completely washed out after only a couple of washes.I tried the 2nd pack i'd bought thinking maybe I hadn't applied it correctly or something(slthough I'm accomplished at hair dying)-but exactly the same thing happened,despite my using speciality shampoos for dyed hair. I was so upset by this as I loved the vibrancy of the colour,but since i'd paid nearly double what I usually pay for my usual "off the shelf"dye,I expected it yo have lasted for more than a week.It wasn't that it gradually faded either,it just completely washed out. I contacted the company's customer service to explain my issue,but I didn't find their attitude to be very accommodating. Firstly they implied that I may need to use more than one pack at once for longer or thicker hair,even though I explained to them that I had medium to fine short hair!. They then suggested that I purchase some of their temporary treatments to use alongside this supposed "permament"dye to maintain the colour longer-which I found to be a insulting suggestion as this one lasted so poorly,I doubted a temporary colourr would fare better. It's such a shame as like I've said the colour initially comes out beautifully vibrant and I loved it.However,i'd definitely recommend to anyone looking for a purple type colour to just stick with the better known brands that have a far cheaper price and definitely more longevity. ## Frequently Bought Together - Smart Beauty Blue Black Permanent Hair Dye, Vegan & Cruelty-Free, 100% Grey Coverage, Midnight Blue, Anti-Breakage Plex Hair Care, For All Hair Types - KISS Lift Up Complete Hair Bleach Kit with Revitalizing Plex Serum to Protect from Damage, Maximum Strength to Lighten Dark or Resistant Hair, Complete DIY 6-Pc Kit - Schwarzkopf Got2b Metallics Permanent Hair Color, M49 Smoky Violet --- ## 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.hr/products/118652545-blue-black-hair-dye-permanent-with-anti-breakage-plex-hair](https://www.desertcart.hr/products/118652545-blue-black-hair-dye-permanent-with-anti-breakage-plex-hair) --- *Product available on Desertcart Croatia* *Store origin: HR* *Last updated: 2026-06-21*
