How to Choose K18 Hair Care
What Is K18 Hair Care?
K18 is a professional hair care brand built around patented K18PEPTIDE™ technology. Its repair products are designed for hair affected by bleaching, colouring, chemical services, heat styling and other sources of damage.
The K18 range has expanded beyond its molecular repair treatments to include everyday shampoo and conditioner, detox cleansing, hair oil, heat protection, dry shampoo, blonde toning, volume and other targeted products.
K18 Leave-In Molecular Repair Hair Mask
The K18 Leave-In Molecular Repair Hair Mask is the brand’s best-known at-home repair treatment. It is designed to help repair damage caused by bleaching, colouring, chemical processing and heat while improving strength, elasticity, softness and manageability.
Unlike a traditional rinse-out hair mask, K18 Molecular Repair Hair Mask is a leave-in treatment. Follow the application instructions on the product page, including the recommended four-minute processing time.
K18 DAMAGE SHIELD Shampoo & Conditioner
DAMAGE SHIELD pH Protective Shampoo provides gentle regular cleansing while helping protect hair from daily damage. Pair it with DAMAGE SHIELD Protective Conditioner for lightweight hydration, softness and protection.
K18 PEPTIDE PREP Detox Shampoo
K18 PEPTIDE PREP Detox Shampoo is the clarifying option in the K18 range. It is intended for deeper cleansing when oil, product residue and buildup need to be removed rather than as a replacement for your regular shampoo every time you wash.
K18 Hair Oil & Heat Protection
K18 Molecular Repair Hair Oil can be used to help smooth frizz, add shine and provide heat protection, while HeatBounce Conditioning Heat Protectant is a dedicated heat-protection product for blow-drying and hot-tool styling.
K18 for Blonde Hair, Volume & Styling
The K18 range also includes TripleBright™ Oxidation Defense Purple Shampoo for blonde and grey hair, AstroLift™ Reparative Volume Spray for volume and styling, AirWash Dry Shampoo for refreshing hair between washes, and FutureIQ™ Biomimetic Hair Longevity Serum.
How to Build a K18 Routine
You do not need every K18 product. Start with your primary hair concern and build from there. DAMAGE SHIELD provides an everyday cleansing and conditioning foundation, while PEPTIDE PREP provides occasional deeper cleansing. The Molecular Repair Hair Mask can be incorporated when repair is the priority, with Hair Oil, HeatBounce or other styling products added according to how you style and finish your hair.
