Incredible
Best purple shampoo ever It smells incredible, a little goes a long way and it doesn’t dry your hair out

Wow it really works!
I just used this on my long curly mixed blonde and gray hair part of which has residual dye on it, and the rest of which is natural. First of all the texture of this purple shampoo is really creamy and wonderful. I really couldn’t imagine that shampooing with those before using several other preparation‘s would actually do anything but it actually cooled and brightened my locks! Bravo!

Decent
A decent purple shampoo that isn’t too drying. The smell is the best part.

Fantastic!
I have tried numerous purple shampoos for my highlighted hair (including the purple olaplex) and this is definitely the winner! This is none drying and makes my hair super soft, especially when used with the bust your brass mask. Can definitely see an improvement to the blonde in my hair when I use this. This has knocked the purple olaplex right off the shelf!

Disappointed
Wanted to love this but whilst the colour correction was OK (not great) the shampoo was really hard to wash out and made my hair feel greasy after only a day.ÂÂ
