There a lots of purple shampoo, if You want an excellent and fast antibrass action this is the answer, and hair are more, more healthy, with a pleasantly touch

This is the best purple shampoo I’ve ever used. Works really great if you have any brassy/ yellow tones in your hair 

I have tried many shampoos for blondes and this is by far my favourite! I use it over 2-3 washes, work it in the hair, comb with a wide comb and let it rest 2-3 min and my hair has perfect cool toned highlights. It is a bit pricey but as I don't use it every wash, it lasts very long time. I am on my second bottle right now and I don't see myself switching to something else!

This shampoo is good, as all Olaplex products, but pay attention, it is very very pigmented. To make it lighter I dilute a small qty with a regular shampoo. Leaves a nice cold grey tonality, not purple or blue. Result is perfect

I actually see the difference in my hair after using this! Works amazing and makes my hair lighter!
