After using this product I noticed my scalp had a purple residue for days, and left my scalp a little itchy. It did brighten my hair and got rid of brassiness. 

It is a good shampoo for blonde hair but to be honest didn’t notice that much of a difference with other cheeper versions of purple shampoo’s 

This shampoo is great for blondes as it really cuts the yellow tones- I tend to shampoo my hair with regular shampoo as it states and then I put the olaplex toning shampoo on like a mask and leave it on fir 10-15 minutes to really cut the yellow tones.  Works fantastic:) 

Unfortunately this was quite drying on the hair so won’t repurchase.

This shampoo is good, I agree with other reviewers that it’s a bit on the drying side but I’ve yet to find a purple shampoo that isn’t. It’s really good at removing the brassy tones! 

I don't think this is worth the price point. It works like any regular lilac shampoo. It does brighten my coloured hair but nothing exceptional. 

I really wanted to love this product. But I absolutely hate this purple shampoo! I tried to give it a fair chance and used it three times but this honestly leaves my hair feeling like straw and I have to deep condition anytime I use it, it literally sucks the life out of my hair. I eventually threw it out. 

Not a fan of purple shampoos in general, expected a bit more from olaplex, the shampoo does dry the hair but i guess thats inevitabe with purple shampoos.

This works well on my highlighted hair but  I do find it drying so need to follow with a hair mask. A little does go a long way and it is very pigmented so I don’t use it anywhere nearly as frequently as other more diluted purple shampoos so it is good value.  

I buy it after years of highlights in my hair of blond and actually this make my hair color look more beautiful and less broke I really love it
