My hair looked so much better after using this product. I had light blonde highlights and against my fair-toned skin, any yellowing made them look horribly unnatural. I used this every, or every other time I shampooed in order to brighten up my hair and add silkiness. This shampoo is a must-have for all highlighted blondes, there is nothing worse than yellowy-blonde hair! I have used several purple shampoos which tended to dry out my hair. This is the most damaged-hair-friendly purple shampoo that I have found. Also, the best smelling :)

I bought this to help take the brass out of my highlights.
This shampoo is packed with pigment! watch out not too stain your shower curtains! and make sure you were gloves!
Even though it seems there is so much of the purple/blue pigment, I found that it just didnt do very well at toning the brass from my hair.. My highlights seem redder and even darker after using this.
It does lather well and does okay as a sulfate-free shampoo.
