Frequently Asked Questions
Get answers to common questions about K18 leave in treatment. 1.7.
Most clients notice improved softness and elasticity within four minutes after application. Full molecular repair benefits develop after multiple uses, with cumulative strengthening and damage reversal becoming more apparent over days and weeks when used as recommended.
Use K18 between professional treatments for maintenance: every 4–6 washes for damaged or color-treated hair, or as needed for visible improvement. Your stylist can recommend a personalized schedule based on hair condition and chemical history.
Yes. K18 is formulated to be safe with color, bleach, and chemical services. It restores peptide bonds without altering color molecules, and can even improve color longevity by strengthening hair structure and reducing porosity.
No rinsing or shampooing is required after the 4-minute leave-in step. Allow the product to absorb fully; styling can proceed immediately. Rinsing afterward will reduce effectiveness, so avoid washing for best molecular repair results.
Results last through multiple washes, often several weeks depending on hair porosity and styling. With regular at-home maintenance and periodic professional applications, clients experience sustained improvement in strength, elasticity, and manageability.
Yes—K18 is specifically designed for severe damage, rebuilding internal bonds at molecular level. Multiple consecutive treatments may be recommended, combined with a tailored salon plan to maximize recovery and prevent future damage.
