New formula easier to use
Just used the new formula for the first time. No need to wet hair first, makes it less messy and quicker to apply. Even colour. Coloured all white roots too!Lids upcyle to light pull .

Semi permanent blue black!
I'm so pleased to have found a semi permanent blue black colour. This felt good on the hair, smelled better than most stuff and didn't hurt my scalp. Will get more.

Lovely hair dye
I love this colour and it doesn't irritate my skin. Only downside is that it was damaged packaging, the box was badly crushed and the outer box was also damaged. Just left on my doorstep and the delivery driver didn't knock. I only noticed it after I received a notification, to say it had been delivered.

Very impressed!
I was looking for a good semi-permanent dye that would give me the colour I wanted without the commitment of being permanent. I am very impressed with the way this has worked on my hair! I had dyed it multiple times previously, and grown my hair out for around a year and a half, so the top was my natural dark blonde colour, and the ends were a mixture of red and copper tones. I didn’t think the colour would take as well as it did, the blue/black certainly exceeded my expectations! Very very happy, will definitely buy again when I want a non permanent change!

Colour changed again!!!
Changed the colour of the hair dye again it used to be a lovely mid ginger colour. Now it looks like a dirty blonde why change something that works for customers.

Beautiful but not accurate shade
Not the colour on the box!!! But it gave me the expected outcome (I had realised the I needed to purchase a lighter shade as they always end up much darker than they say) and I’m really happy with it. So I’d buy again but be careful if you went the colour on the box. Here is a before (in the burgandy cardigan) and after

Fantastic and great service. Shipping was faster than expected.
1.) Use gloves and pour the coloring bottle into the developer shake to stir evenly, 2.) Apply the colour leave to act recommended time. 3.) Follow with conditioner rinse
