FREQUENTLY ASKED QUESTIONS

Depending on your hair length and thickness, the 15ml travel size provides approximately 10 to 15 treatments. Since K18 is highly concentrated, starting with just 1 pump per application is usually enough for medium-length hair.

No! For K18 to work effectively, do NOT use conditioner after shampooing. Conditioners leave a protective coating on the hair shaft that blocks the K18 peptide from penetrating deep into the inner layers of the hair. Simply shampoo, towel-dry thoroughly, and apply K18.

No, K18 is a leave-in treatment. Do NOT rinse it out. Leaving it in allows the bioactive peptides to continuously rebuild and reconnect broken keratin chains in the hair.
