Review: Gorgeous, glossy blue/back colour - I LOVE it! - I coloured my hair blue/black using this home dye kit a week ago and have been so pleased with the results. I’ve been to the gym multiple times and NOT sweated blue sweat (which my previous brand had me doing for at least a week after colouring) and my hair is shiny and glossy with more blue than I was expecting. It’s ace. I love the fact it’s cruelty free and kinder to my hair than other bands too. I’ve never been so glossy! At least half a dozen people have said how amazing it looks and asked where I had it done - when I say I did it myself they’re amazed. Still got to see how it fares when I go swimming next week but, assuming I survive that without turning the pool a funny colour (!) it’s a definite, 100% thumbs up from me :)
Review: Best blue black results I've ever had on black hair - Ok pros:- The colour is the best colour result I've ever had on black hair. You can see the blue very clearly in any light. It's a clear blue hue The colour stays I've had this on about 2 weeks now and now fade so far (I'm using maui shampoo and conditioner) The condition this dye puts you hair in is surprising. It literally fixes your hair while dying it. CONS:- It's messy to apply. Extremely thick. Stains absolutely everything. USE VASALINE ON EARS NECK THROAT AND FACE AND ARMS WRIGHTS SOAP (COAL TAR) WAS RHE ONLY THING THAT REMOVED THE STAINS. I've been dying my hair for over 20 years. This by far is the messiest dye but one of the best blue blacks I've come across.

### ⭐⭐⭐⭐⭐ Gorgeous colour, very happy
*by A***. on 23 December 2023*

I always get blue black dye because it gives a cooler tone even if you can't see the blue (it never shows in my hair). This one most definitely has a blue tint to it. My hair is soft and shiny. I saw some reviews it's messy to apply, I personally didn't experience this. It's quite a thick formula and I found it probably one of the easiest I've used. My only complaint is probably that the bottle is quite soft plastic so it's not that easy to squeeze the dye out. I usually have to put loads of conditioner on when washing out to get a comb through my hair but not with this one, I shampoo'd with a colour fast shampoo as advised but did not need conditioner. Will be switching to this brand permanently!
