My hair stylist turned me onto this product. I have naturally curly hair which tends on the dry side and I color my hair. I have searched for a product for years that does what this product does for me. It is amazing the transformation in just one application sis for my hair. I find I actually need less styling product also, my hair now has a healthy moisture content and my curls have never looked better.
All the products I have tried to nourish and hydrate my curls have only done the opposite.
This product helps with my frizz and I find I can extend time between washes.
Call my 100% happy with K18 Leave In.
Highly recommend

My hairdresser started using this on me as my hair had started breaking off and drying out after a recent weight loss. The changes in my hair with this product along with the peptide prep shampoo are unbelievable! I now only wash my hair every 2-3, sometimes to the 4th day and my hair is so much healthier and fuller. Love your products!

My hair has been breaking so much less since starting K18 - the baby hairs around my crown are actually growing long for the first time! A life saver for my color treated hair

I’ve been using this product along with a K 18 molecule repair oil for about three months and they have changed my hair. Before using them, my hair seem to be a little dry not shiny sort of blah but now after using them, my hair shines. It’s beautiful. I just love it..

- Maria K.Verified BuyerReviewingLeave-In Molecular Repair Hair Mask Deluxe SampleI recommend this productRated 5 out of 5 stars1 year agoSo far so good!
I have extremely dry gray hair. Yuck. I want beautiful lusterous and shiny gray hair. I researched online about the best way to achieve that and k18 Was mentioned the most. So far I've done the mask with prep shampoo. I followed up with the oil. It looked so good that I ordered the regular shampoo and conditioner. Its been less than a week. I've used each product one time and my hair is already way less frizzy. I'm Very happy and look forward to seeing even more improvement over time.
