A treatment for all hair types that clinically reverses damage in 4 minutes.

The science is complex but here’s everything you need to know about why K18 is a scientific breakthrough—and how it can bring your damaged strands back to their original, youthful state.

When hair gets damaged, the polypeptide chains (keratin chains) that make up the inner structure of hair strands become weakened and break. For context, there are billions and billions of keratin chains in a single strand of hair. When these are damaged, hair’s core structure becomes compromised and, as a result, it loses its strength, elasticity, resiliency, and shine.

Using K18 at home

MESSAGE FROM CARMEN

The K18 Mask is the most effective hair mask I've ever used, and I've cycled through many treatments over the years. However, the first time I used it, I was not 100% Sold, which is why the instructions explained using it six times consecutively before dropping down to every three or four washes for maintenance.

Around the third application, you notice the most significant difference in touch-ability. The only hesitation I can think of over this mask is the price, which is steep for such a small bottle, but I'm a big believer in you paying for what you get.

If there were ever an excuse to splash out, this is the one, a science-backed (and pro-loved) add-on treatment perfect when used in Bleach + Color, Relaxers, Perms, the list goes on.
