Protects & repairs your hair. Hair serum is a liquid-based treatment usually formulated using silicones that provide a protective layer to the hair cuticle, helping in smoothing frizz. This smooth layer then reflects light, which is how serum gives your hair a shiny, non- greasy look and feel. Frequent exposure to heat styling tools for hair styling can damage hair cuticle, causing it to crack, bend and lift. As a result, Hair become dull, lifeless and frizzy. Trichup Hair Serum – Thermal Protection provides an effective defense against the intense heat generated with heat styling equipment by forming a protective layer on Hair cuticle. That makes hair less susceptible to breakage and damage. Trichup Hair serum helps make hair smooth and manageable.
