Get answers to common questions about K18 Treatment.

K18 uses a patented peptide to reconnect broken keratin chains. In-salon chelating removes mineral buildup, then the repair mist and mask deliver peptides deep into the cortex for rapid, lasting strength and improved elasticity after one or several treatments.

Yes. K18 is formulated to work on bleached, colored, and chemically treated hair. The chelating step improves color longevity, while the peptide mist and mask restore integrity without altering color or interfering with salon services.

Individual longevity varies by hair condition and aftercare, but most clients report noticeable improvements lasting four to six weeks. Regular home use of the K18 mask and avoiding harsh styling prolong and reinforce repair results.

Severely damaged hair often benefits from a series of three to six treatments spaced weekly or biweekly. Your stylist will assess progress and may combine chelating, the repair mist, and the mask until desired strength and elasticity are restored.

Yes, in most cases coloring can be done the same day. The chelating step prepares hair for color, and the K18 protocol is designed to be compatible with salon chemical services—your stylist will confirm timing based on your hair's condition.

Use the K18 home mask or recommended maintenance products, avoid high-heat styling, and limit harsh shampoos. Gentle detangling, heat protection, and periodic touch-up treatments keep bonds strong and extend salon results between visits.
