I’ve tried so many purple shampoos and a few of the did the job but were overly drying ... I thought I’d try this as it was less expensive than Paul Mitchell which my hairdresser recommended but it had some fantastic reviews... so here’s another one! I use this like a normal shampoo to maintain my ash blonde lengths and I leave it in for five minutes if I need more colour correction. It doesn’t dry my hair out at all, smells amazing and when used with the conditioner my curly, frizzy hair is actually shiny

Decided to give this a try to change from my previous shampoo and I can’t believe what a difference it made. My hair look much lighter and brighter now. I even had a few people complementing me on my hair colour!

This is the best purple shampoo I have ever tried. I could see results after the first use, literally. I dye my hair blond, and it turns brassy rather quickly. This shampoo reversed it after one use! This is amazingly effective. Side notes: the shampoo might stain slightly so better use gloves or take a long shower to wash everything away. Another this - the instructions say don't leave more than 5 minutes on the hair - I have a feeling you better adhere these instructions. As I said, the shampoo is amazingly effective - leave it too long it WILL cause unwanted side effects.

the best shampoo for taking all brassy tones out of a blonde colour. can turn your hair quite blue quite quickly though so don't leave on too long!

Love this I’ve been trying forever to find a shampoo that both helps with colour maintenance aswell looking after my hair at the same time, and the added olaolex technology is just amazing!
