Anti-frizz serum is a hair care product designed to reduce frizz and enhance smoothness in hair. It typically contains ingredients like silicones, oils, and humectants that help to seal the hair cuticle, preventing moisture from causing frizz. This serum can be applied to damp or dry hair, making it versatile for different styling needs. Using anti-frizz serum can help achieve a polished look, especially in humid conditions where hair tends to become unruly. It is suitable for various hair types, including curly, wavy, and straight hair, and can be used as part of a regular hair care routine to maintain sleek and manageable locks.
