I love the result, I've never had such an intense color before It's the first time I'm looking forward to coloring
Absolutely LOVE the permanent 'Black Sapphire' and 'Amethyst Purple'. I mixed about a teaspoon of each and mixed it with the full bottle of developer to achieve a long lasting silver (applied to bleached/yellow hair). Best vegan permanent hair dyes by far!
It was easy to use great colour and didn't smell as bad as other hair colours
Now this one is lush. Love it. Used it to cover my orange hair catastrophe.
