GlossaryCuticle

outermost layer of a hair strand, protecting inner layers

The cuticle is the outermost layer of a hair strand, composed of overlapping, scale-like cells that protect the inner layers of the hair shaft. It acts as a barrier against environmental damage and helps maintain the hair's moisture balance, contributing to its overall strength and shine.
