How to Use K18 Complete Repair Routine

Step 1 — Detox

Replace your regular shampoo with K18 Peptide Prep™ Detox Shampoo once a week or as needed. Massage into wet hair and scalp, then rinse thoroughly. Repeat if necessary.

Step 2 — Repair

After shampooing, do not condition. Towel-dry thoroughly.

Apply 1–3 pumps of K18 Leave-In Molecular Repair Hair Mask, depending on hair length and density. Start at the ends and work towards the roots.

Wait 4 minutes. Do not rinse. Comb and style as usual. For intensive repair, use for the first 4–6 washes, then as needed.

Step 3 — Strengthen & Smooth

After the 4-minute K18 Mask wait time, apply 1–3 drops of K18 Molecular Repair Hair Oil through mid-lengths and ends.

For use on damp hair, K18 recommends waiting another 4 minutes before styling for maximum strengthening benefits. The oil can also be applied to dry hair as a finishing treatment to smooth frizz and add shine.
