How to Use the K18 Mask at Home

The K18 Leave-In Molecular Repair Hair Mask is the only patented, bioactive peptide treatment with clinically proven results. It repairs and reverses hair damage caused by chemical treatments, heat exposure, or mechanical styling.

Application steps:
Wash your hair with the K18 Peptide Prep Detox Shampoo—skip the conditioner. Then carefully towel-dry the hair.
Start with one pump of the K18 mask. Use a little more if needed, depending on hair length, thickness, and condition. The mask goes a long way—a small amount is sufficient. Work it in evenly, section by section, from the roots to the ends.
Leave the mask on for 4 minutes to activate the peptides.
Do not rinse out.
If needed, apply the K18 Damage Shield Conditioner after the mask and then rinse it out.
Style your hair as usual.

Note:
If you regularly use rich products such as oils, silicones, or film-forming styling products, we recommend using the K18 Peptide Prep Detox Shampoo beforehand. Residues can interfere with the mask’s effectiveness—a deep cleanse creates the optimal foundation.
The mask can also be used as an effective at-home treatment independently of a professional K18 salon treatment.
