Get answers to common questions about K18 Treatment.

Many clients notice immediate softness and improved elasticity after the in-salon application. The K18 peptide works within minutes and continues molecular repair over subsequent days and washes, making hair progressively healthier and more resilient with each treatment.

Yes: K18 is formulated to reconnect keratin chains regardless of chemical history. It’s safe on color, balayage, bleached, and permed hair, helping restore elasticity and reduce breakage. We’ll assess your hair to ensure optimal results and proper timing.

While results are immediate, longevity depends on hair porosity and styling. The peptide repair remains inside until hair grows out or is excessively damaged; most clients maintain benefits through several washes. We recommend periodic maintenance treatments every 4–6 weeks for optimal strength.

Yes. K18 can be used before or after color, lightening, or chemical services to rebuild strength and reduce breakage. Timing varies—often applied after shampoo before styling or after chemical neutralization—so we’ll coordinate with your stylist for best results.

No. K18’s peptide formula penetrates and repairs at the molecular level without coating the hair surface. It doesn’t weigh hair down like heavy conditioners; instead you’ll get improved manageability, natural movement, and a sleeker feel without loss of volume.

Use sulfate-free shampoo and gentle styling, avoid excessive heat, and follow any recommended K18 home products or take-home treatments for extended repair. Regular trims and periodic in-salon K18 touch-ups will help preserve strength and elasticity over time.
