The best way to check the colour your hair will go after using this dye is with a strand test.

My hair was already bleached
My hair was already bleached in a unevenly way, so the colour has variations of blue which I particularly like, going from an electrical blue to turquoise. . It's very easy to apply, it feels good, and you can always leave a little bit in the bottle (I have short hair) to apply again with your conditionner few weeks later. I love Bleach London products!

I just adore this colour
I just adore this colour ! Leaves my hair soft and not weighted down like most temporary dyes, even colours my natural darkest brown hair. Bleach London is my favourite brand, I was so happy when you brought back this darker blue, thank you

Beautiful blue
Colour is beautiful hair still feels soft just make sure your hair is solid platinum blonde before applying the dye everywhere because if you have a brassy yellowish light blonde then parts of your hair will show up as a dark green also the blue applies really well to a cool platinum blonde blue is beautiful.

Mixed it with violet and got an amazing colour!
I wanted a change from purple to something a bit darker but I couldn't find anything elsewhere. I had been using Bruised Violet for like two years, and I decided to give it a go and mix it with Wolfalice Blue. . . I couldn't be happier with the result. I put in 50/50 in the mixture and the colour I get is a much darker purple which doesn't wash out as pink, like Bruised Violet on its own. A lot of people have made nice comments about my hair and how lovely the colour is. As usual, it smells nice (a bit stronger than Bruised Violet though), it mixes well and it's easy to apply. My hair is black with patches of grey so I use it to cover the grey. I leave it on my head for 2 hours and then I wash it. I do my hair around every 7-10 days to keep the intensity of the colour. I'll definitely keep on buying these colours!

Blue weekend
This colour is great and really lasts. I mix it with Bruised violet for a Bluey Purple and it fades to a lovely baby blue. Definitely wear gloves as it stains skin!
