do's + don'ts
DO use a clarifying shampoo if you’re a heavy product or dry shampoo user to remove buildup and help our peptide penetrate and get where it needs to go.
DO wait the full 4 minutes before styling or applying other product
DO use every 4-6 shampoos consecutively to see and feel ongoing results
DON’T condition your hair before application (trust us, most won’t need it after K18, if you still need, add a leave-in after the 4-minute window is up post-application)
DON’T overuse, a little goes a long way.
DON’T rinse out. This is a leave-in, so you know, leave it in!
