    • REALLY GOOD FOR A DEEP CLEAN
I genuinely love this shampoo, although I wish it were cheaper and more affordable. As someone with frizzy, curly hair, I've found that after using it, my hair feels really clean, and the quality is excellent.

    • Transformed my hair damaged by well water
My hair got very damaged this past year due to an issue with the water softener on the well and an over abundance of copper and other metals. Saw a random video about this product and decided to try it out, assuming it really wasn’t gong to do anything because my hair was so damaged and dry. It felt like straw, literally, and was breaking off in spots. I had cut off quite a bit of the length and added layers to try to take out the damaged sections. I tried several detoxing shampoos going forward to prevent more damage with no effect other than some drying my hair out more. Even with the water softener fixed, the metal is still very high. Bought K18 and it’s been amazing. I can use it every day if I want. I lather it and let it sit for a few minutes while I shower and then rinse out and condition. It does not dry my hair out at all. My hair feels softer than it has the entire year. The shine has come back. I’m incredibly thankful for this product. I don’t write very many reviews, but I thought this might be helpful to those going through the same thing. ... show more

    • Really good non drying clean
So I’ve been a user of k18 products for a few months and decided to get this one during the prime day event and love it. It is definitely worth the money. I’ve used the L’Oréal refine cleanser, ouai clarify shampoo, the clarifying scrub from Briogeo and this is my favorite clarifier so far for my long blonde highlighter hair. It takes out the impurities without stripping my scalp and making it too dry it too oily. I use this before I then use the k18 moisture shampoo and it’s the perfect combo for dry, oily or normal hair. It will give you a good clean without a strong scent. ... show more

    • Promotes cleanliness and maintains hair color
I am impressed with the quality of this detox shampoo. It keeps the color of dyed hair for several washes.

Price is steep but you get your value for your money ! It does exactly what it needs to do ! I transitioned my hair from hot pink to blue black this shampoo helped removed all the build up . Smells great ! & left my hair shine , now this product does leave your hair dry, but you should pair with a hydra mask to hydrate your hair right after . The quality of the product speaks for it self ... show more
