K18 Pro - Repair Service Kit

K18 Pro - Repair Service Kit

K18REPAIR™ is a 2-step, salon-exclusive damage repair service powered by the patented K18PEPTIDE™. Designed for all hair types, it works to protect, strengthen, and preserve hair integrity during lightening, coloring, chemical services, and heat styling*—so you can feel confident delivering hair like new* with every service.

More than just a bond builder, K18REPAIR™ goes deeper. While traditional treatments work on the outer cortex, K18PEPTIDE™ is biomimetic to hair, traveling beyond the cortex to reconnect broken disulfide bonds and polypeptide chains—the true building blocks of hair structure.

This molecular-level repair creates immediate and long-lasting results that won’t wash away with water, restoring strength and elasticity from the inside out.

step 1: repair hair to the core pre-service

PRO mist

• Fortify hair to restore up to 99% elasticity
• Improve hair’s resilience to prevent damage during + after services
• Deliver stronger hair over time
• Make color last longer + fade slower* when paired with K18 mask usage at home
• pH 7.5-8.0 swells the hair cuticle open for effective repair pre-service

step 2: reverse damage post-service

PRO mask

• Reverse damage from lightener + color, chemical services, and heat
• pH 5.0-6.0 helps close the cuticle + seal K18PEPTIDE™ into the hair for lasting results
• Soften + detangle all hair types with lightweight emollients
