When to Use K18 Hair Mask
Use the K18 Hair Mask whenever your hair needs intensive repair — particularly after bleaching, colouring, relaxing, perming, or heat styling. It is ideal as a K18 hair treatment after bleaching, as a leave-in hair mask for damaged hair, or as a regular maintenance treatment every 4–6 washes to keep hair in peak condition. It can also be used as a K18 hair mask for curly hair to restore curl definition and reduce frizz.
How to Use K18 Hair Mask
- Shampoo hair with K18 PEPTIDE PREP™ Detox Shampoo. Do not condition.
- Towel dry to remove excess water — hair should be damp, not dripping.
- Apply 1–2 pumps of K18 mask from ends to roots, working through all sections.
- Leave in for 4 minutes. Do not rinse.
- Style as usual. No heat required to activate.
For best results, use after every wash until hair feels fully restored (typically 4–6 applications), then once every 4–6 washes for maintenance.
