Must have
GET IT. if you have that flaky white stuff in your hair that’s not dandruff, that is build up from natural oils form your head and from your shampoos and whatnot. This is a very concentrated shampoo that cleans it out in one wash. I’ve always struggled with it and now I use this about once a week and it stays away!

The best clarifying shampoo I've ever used. It builds up to a good lather and effectively cleanses the scalp without causing dryness.

A weekly must before K18 leave in treatments
In order to get the best results with K18 leave in treatment, you need to get all the build up stuff out so that the treatment can penetrate. It's my first time buying this product as I used other prep items but this one is best matched with K18.

Just buy it, period
I’m surprised at people saying it’s not color safe. I have always color my hair with vivids, you can look at those colors wrong and they’ll get three shades lighter. I used it on my grape-purple roots, ready to basically turn them lavender, but my hair was so stiff and waxy from product I had to do something. Imagine my surprise when it looked EXACTLY the way it did before I washed, and made my hair feel so soft and clean! The first photo was when I first got it done, and the second a couple days after washing with this shampoo

Holy grail clarifying shampoo
This is a great clarifying shampoo. I feel it leaves my hair very clean but doesn’t make my hair feel super dry like other clarifying shampoos do. I also like the fragrance of this shampoo

Forever buying & using this
I’ve been using this for a few months now. My scalp usually still smells after a good wash (even scrubbing hard) but this has made my hair and scalp smell so much better. It actually smells like I’ve washed my hair. It’s non-greasy, non-irritating, and overall an amazing shampoo that CLEANS your scalp and hair. I plan to continue purchasing this as long as possible. It doesn’t have a very strong scent, but it doesn’t stink either. It really gets your head clean.
