The K18 Blowout
What the K18 Salon Professional Treatment Is
The K18 salon professional treatment (often called K18REPAIR™) is a 2-step, salon-exclusive molecular repair service designed to strengthen, protect, and reverse damage to the hair at its core — not just on the surface. It uses the brand’s patented K18Peptide™, a bioactive peptide that mimics natural hair building blocks to reconnect broken bonds inside hair fibers.
Main components used in salons:
-
K18 Professional Molecular Repair Hair Mist — a prep mist applied before chemical or heat services
-
K18 Professional Molecular Repair Mask Step 1 & 2 or similar pro masks — a post-service repair mask
Benefits of the Salon Treatment
Stronger, more resilient hair — Pre-service prep improves how hair withstands chemical/heat stress.
Deeper repair — Works on the hair’s internal structure (keratin and disulfide bonds).
Better salon results — Color looks brighter, fades slower; texture stays healthier after processing.
Fast and efficient — Designed to fit into typical salon appointment timing
