How to Use K18 leave-in Molecular Repair Hair Mask

In the shower

Use after shampoo, never conditioner

Out of the shower

Dry thoroughly with a towel.

Start with 1 K18 face mask pump and add more as needed based on length, thickness and condition.
Work evenly on hair from tips to roots, one pump at a time.
Let stand for 4 minutes to activate.
Do not rinse.
Comb as usual.

Use a clarifying shampoo if using a heavy product or dry shampoo to remove buildup and help our peptide penetrate and get to where it needs to go.

Wait a full 4 minutes before styling or applying another product.

• Use every 4-6 shampoos consecutively to see and feel continuous results
• DO NOT condition your hair before application (trust us, most will not need it after K18, if you still need it, add a leave-in product after the 4-minute period after application ends)
• DO NOT overuse it, a little yields a lot.
• DO NOT rinse. This is for quitting, so you know, leave it!
