Triple-Action Formula
Three Ingredients. One Transformation.
Keratin Bonds
Keratin fills in the gaps along the hair shaft — rebuilding structural integrity from the inside out for smoother, stronger strands.
Argan Oil Seals
Moroccan argan oil locks the keratin in and seals the hair cuticle — locking out humidity, blocking frizz, and locking in mirror shine.
Collagen Plumps
Hydrolyzed collagen adds volume and elasticity — so hair feels thicker and more resilient with every use.
Works in 9 Seconds
Apply to clean damp hair, wait just 9 seconds, rinse. No heat cap, no waiting, no complicated process.
How To Use
Salon Results in 3 Steps
Wash hair with your normal shampoo. Towel dry until damp but not dripping wet.
Apply the KeraSilk Mask evenly from mid-length to ends. Leave for 9 seconds then rinse thoroughly.
Style as usual. For deeper treatment leave on 3 to 5 minutes. Use once or twice per week.
