Frequently Asked Questions
K18 Leave-in Molecular Repair Hair Mask features K18PEPTIDE™, a proprietary biomimetic peptide complex that mimics hair's natural protein structure. The formula also contains amino acids and conditioning agents designed to support hair strength and elasticity without silicones or sulfates. This peptide-based technology targets the innermost layers of damaged hair to help restore structural integrity.
Yes, K18 Leave-in Molecular Repair Hair Mask is specifically formulated to support damaged and chemically processed hair, including color-treated, bleached, and permed hair. The biomimetic repair technology works to strengthen compromised strands without harsh chemicals. However, if you have a sensitive scalp, apply the mask to mid-lengths and ends rather than the scalp area.
For best results, use K18 Leave-in Molecular Repair Hair Mask 2-3 times per week, or as needed based on your hair's damage level. You can apply it after shampooing and conditioning, then leave it in without rinsing. For severely damaged hair, daily use is safe. Adjust frequency based on how your hair responds—some users see optimal results with weekly application.
