• DO use detox shampoo before the mask to remove buildup and help our peptide penetrate and get where it needs to go.
• DO wait the full 4 minutes after mask application before styling or applying other product.
• DO use for 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!
