    Glossary Hair Shaft Structure

    three main layers of a hair strand: cuticle, cortex, medulla

    The hair shaft structure refers to the three main layers of a hair strand: the cuticle, cortex, and medulla. The cuticle is the outermost layer, made of overlapping cells that protect the inner layers. The cortex, which is the thickest layer, contains keratin and pigments that give hair its strength, color, and texture. The medulla, found in thicker hair types, is the innermost layer and consists of a soft, spongy core. Understanding these layers is crucial for diagnosing hair conditions and developing effective hair care treatments.
