I’ve used many a purple shampoo and always found them drying until I found this redken shampoo. It leaves hair feeling soft, fully removes yellow tones and a little goes a long way. Highly recommended 

This shampoo is amazing. Doesnt dry hair out like other color shampoos can.

This is the best purple shampoo I have ever tried. It's economical as it's so thick and really does a good job of keeping my hair bright.

The best purple shampoo I have ever used. Really thick, so you only need a little. Gets rid of any tone that is too warm.

I really couldn’t be without this for my bleached hair. It stops all the brassy tones but it’s still bright. Definitely doesn’t dry my hair like some purple shampoo. Neither does it leave a purple tinge.  Sadly look fantastic have been unable to help me with buying the larger better value bottle. When checking out it says unable to deliver. I have contacted customer services several times only to be basically fobbed off with the same answer ‘it should be fine’ that doesn’t solve the issue.
