What is K18 Leave-In Hair Mask and What It Does?
The haircare world has seen many trends come and go, but the K18 hair mask is making a lasting impression. Unlike traditional conditioners or masks that only smooth the surface, K18 goes deeper — working at the molecular level to repair damaged hair from the inside out.
What is the K18 Hair Mask?
The K18 Leave-In Molecular Repair Hair Mask is a revolutionary treatment designed to restore hair’s strength, softness, and elasticity in just four minutes. What makes it different is its patented K18Peptide™, a breakthrough molecule that travels deep into the inner layers of the hair to reconnect broken keratin chains.
Damage from colouring, bleaching, heat styling, and chemical treatments weakens the hair’s structure. The K18 hair mask helps reverse this damage by mimicking the natural building blocks of healthy hair, effectively bringing it back to a near-virgin state.
How Does the K18 Hair Mask Work?
K18 is not your average deep conditioner. While many masks simply coat the hair, K18 penetrates the cortex — the innermost part of the hair shaft. The patented K18Peptide™ is the result of 10 years of biosciences research, designed to permanently heal hair damage with continued use.
The application is simple:
-
Shampoo your hair (no conditioner).
-
Towel dry thoroughly.
-
Apply 1–3 pumps of K18 (depending on hair length and thickness).
-
Leave in for 4 minutes.
-
Do not rinse — style as usual.
Because it’s a leave-in treatment, it continues to work even after you’ve styled your hair.
