Love all Olaplex Hair Products. It has consistently kept the yellow/bronze out of my blonde. You only need a wee bit to lather.

I will add, if you leave it on too long it can make your blonde look more like the frost blonde. This has been the best purple shampoo that I have used.

Best product for processed, damaged hair. This is after one use so I’m sure I will have to use again, but works amazing compared to other products I will be using nothing but this in the future. Just got my hair done last week and ordered this to make sure I wasn't gunna be brassy, I read a lot of the reviews and one girl said she put it on her dry hair and I should not have done this, turned my hair purple a little bit where my highlights are and oof.

) I use this about once a week and leave it on for a few minutes. Product is amazing just wish it wasnt so pricey for a little bottle. My hair has naturally grown in white / grey over the past 10 years after dying it blonde for 30 years. I should have just followed the directions and put it on wet hair.
