Frequently Asked Questions

Get answers to common questions about K-18.

A typical K-18 service takes about 20–30 minutes from application to activation, plus any additional styling time. We allow time for consultation and blow-dry so the full appointment may be 45–60 minutes depending on styling needs.

No — K-18 is designed to be color-safe and will not lift or alter your hair's tone when used correctly. It repairs peptide bonds without changing color, so it's safe after coloring, lightening, or glossing services.

We recommend waiting at least 24–48 hours before shampooing to allow the K-18 peptide to fully integrate and strengthen bonds. For best results use gentle, sulfate-free shampoos and avoid clarifying treatments immediately after application.

Frequency depends on damage level. Many clients see major improvement after one session, then schedule maintenance every 4–6 weeks or before chemical services. Your stylist will recommend a personalized plan based on hair porosity, texture, and styling habits.

K-18 is generally well-tolerated and applied to the hair shaft, not the scalp. Clients with extreme sensitivity, allergies, or pregnancy should consult their doctor; our stylists can perform a patch test or recommend alternatives when necessary.

K-18 works differently — it repairs peptide bonds rather than only coating hair. It can reduce the need for heavy conditioners, but many clients combine K-18 with regular conditioning to maintain softness and manageability between salon visits.
