AHHHHH-MAZZZING!!!

Amazing shampoo! First time I heard about K18 was from a new stylist - she put the K18 leave-in molecular repair hair mask on my hair after my bleach/color job and I love how it made my hair. I bought some for myself and used with my regular shampoo. Worked pretty good. Enough to buy more. Went to a new stylist and my hair got burnt up. Bad. So I tried this product and bought the K18 shampoo and WOWWWWW!!! - I can’t even believe the difference when used together! My fine, thin, very broken bleached hair looks much healthier and shinier after just 2 washes and 2 treatments with K18!! I wish I would have taken pics! I usually have to wash every day or every other day but went a whole week with using dry shampoo only once and it wasn’t dry at all. It feels and looks so much healthier! I can’t wait to try their K18 conditioner when I’m done with this treatment! (Ie: Use the treatment 4-6 times after shampooing with no conditioner then switch to conditioner and use the treatment just as needed!) I’m so glad I found this! Thank you K18!!!

Great everyday shampoo

I love all my K18 products! Are they spendy, yes, but they are so worth the price. A little goes a long way when using this shampoo. It cleans my hair without stripping it or making my hair feel dry or brittle. Definitely recommend!

Has done wonders for maintaining my hair and the abuse it gets. Highly recommend if you abuse your hair with bleach and heat.

Great Shampoo Great

The best shampoo, my hair was coming out droves and my stylist suggested this product for my hair while I was on medication. The other day she said my hair is back healthy . Took about three months turn around .

Not sure it’s worth the hype?

I guess? Nice shampoo but wasn’t life changing. It washed my hair and had a nice scent— not too perfumed. I don’t want to knock it but I think it’s just fine. Hair is soft and moisturized.

Best shampoo ever!

I had heard about this line of hair products and tried the shampoo. My hair looks, feels and smells great! I typically use leave in conditioner to detangle my hair but no need after using this shampoo.
