GlossaryHair Surface Roughness

texture and smoothness of outer hair layer

Hair Surface Roughness refers to the texture and smoothness of the outer layer of hair strands. It is influenced by factors such as cuticle health, environmental damage, and hair care practices. Rough hair surfaces can lead to increased friction, tangling, and a dull appearance, while smoother surfaces reflect light better and feel silkier.
