Excellent!!! Just follow up with conditioner
I have dark blonde hair with light blonde highlights. My hair gets super brassy! I only color/tone every 12 weeks. This made a HUGE difference in my hair. I only used 6 pumps, lathered up and let it set for 3 minutes minute. Immediately followed with a good conditioner, which I left on for five minutes.

Perfect purple shampoo
I wish I took a before picture, because this shampoo removed some much brassiness/golden tone. I have tried Olaplex and Kerastase, this k18 is elite. Perfect color and leaves my hair so much softer than the others!
