KERASILK’s Liquid Cuticle Filler is a heat-activated spray designed to smooth and visibly strengthen strands. Powered by biomimetic silk and vitamin-rich blue lotus extract, the high-performance formula helps improve hair texture and shine during styling, keeping it soft and hydrated. Lightweight and easy to use, the spray supports a sleeker, more polished look without adding stiffness or weight, leaving hair feeling more manageable with every blow-dry. This non-rinse hair care provides an immediate dose of intense hydration and nutrition, smoothing and restoring natural shine and structural integrity. It promotes regeneration, aids detangling, and acts against frizz, leaving hair smelling great. The filler activates and repairs the hair surface, optimizes it, and provides long-lasting protection for the cuticle, shielding it from heat stress factors by up to 93% and making hair up to 14 times more resistant to heat. It also offers long-term protection against frizz and static. The formula is vegan, naturally free from mineral oils, sulphates, microplastics, silicones, and colourants, with 95.5% natural origin ingredients that are 99.6% biodegradable. Simply spray into towel-dried hair and style as usual. Do not rinse, spray into eyes or on mucous membranes.
