    Unbelievable! I never leave reviews because I am ultimately lazy but I couldn’t let this go without saying something. This product is actually incredible, my hair feels like silk and it looks like I’ve just had a hair cut. I’ve never ever experienced a product that worked so well. I’m in for life.

    As a bleach blonde this stuff is a lifesaver. Repeat buyer and will be buying again.

    Due to a dying and stripping accident, my hair was extremely chemically damaged and it was going to have to be all cut off. After purchasing this product, my long hair is back to a healthy looking condition (about 90% better). This is my third bottle which will take it back and beyond what it was. As pricey as it is, it was worth it.

    My hair should be looking like a clown with how thin it it and how many times I have bleached, chemically straightened it and generally dyeing with colors. This product helps with the damage and make it become as healthy as possible. I will continue buying! ❤️

    Amazing. Repaired my super damaged hair very quickly. I’d tried Kerastase Resistance and Olaplex previously, and for a long time … they don’t even come close to the repair I got from K18

    The first time I used K18 I noticed a significant difference.
    My hair is coarse, dry and brittle this product is like magic! I’ve spent $1000’s on haircare products promising ‘amazing results’ but not for me, however K18 is working for me! I love it and how it’s healing my hair to be healthy!!

    Amazing product. I’d have given up on being blonde by now if not for this. It’s easy to use and has repaired incredibly damaged bleached hair to the point where it actually feels like healthy hair again.

    I love how quick it is to use, just pop it in post shower no need to rinse! It’s done wonders for my bleach damaged hair.
