Not for natural grey hair
Not the best for natural gray/white hair. Definitely leaves a purple tint. Resolved this by mixing with a non purple shampoo, and rinsing quickly. I do notice some improvement from brassiness. I like the foam. A little drying, I won’t buy again but it is a good product just better for people with color treated hair it would seem.

Did not work. :-(
I followed the directions, this did not work for me. I have used a lot of purple shampoos and this didn’t work. My hair is as brassy as it was before k18 purple shampoo treatment, a bit shocked to not see even a little cooling, my hair usually takes purple shampoo quickly and noticeably. Fine, curly bleached hair.

Not worth the dollars
I wasn’t impressed with the shampoo and had to return it. It didn’t do anything to tone my yellow ends and didn’t even make my hair feel soft. Expensive so am very happy with Sephora’s return policy. I went back to my tried tried and true Alurum

Perfect for a refreshed look
After having dark hair for the longest time now I went a lot lighter and I needed a purple shampoo. So I went with the K18 line. This works amazingly good! Brightened to the correct level without looking dull. It’s so nice to be blinder again and the grassiness just gets taken away with a wash!

Excellent Purple Shampoo
Removes brassiness from the first wash. I was incredibly impressed with its performance and I continue to use this since I have well water. It’s truly a game changer, but like others have mentioned, you will still need to make sure you condition afterwards.

nice purple toning shampoo
I purchased this product after seeing it recommended by a hairdresser online who specializes in gray blending as I am currently going gray; I have used other purple shampoos and masks and conditioners; I like the foam consistency of this shampoo; it doesn't make a mess in my shower; i read all the reviews before using it and so I was sure to use a nourishing mask after shampooing; this shampoo did tone my blonde and grey maybe a little better than other products I had been using; its pricey, but I only use it maybe once every 10 days and it should last a long time

Good, not amazing
Like other reviews, my hair did feel drier after using. This was easily remedied though with a hair mask and some oil. I struggle with hard water discoloring my hair and feel like this has helped! I love that it doesn’t leave my hair purple.

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!

Was blond before using this shampoo, it removes yellow and white colors. My hair look very dark after, without blond. Do not recommend, especially for this price. 10$ any purple shampoo is better.
