hair morphology

Hair morphology refers to the structure and characteristics of individual hair strands. A hair strand consists of three main layers: the outer cuticle, the middle cortex, and the innermost medulla. The shape and size of the hair, as well as the texture and thickness, are influenced by factors such as the diameter of the hair follicle, the curl pattern, and the distribution of melanin. These features are determined by genetics and can affect how hair looks and behaves—whether straight, wavy, or curly—and its strength and appearance. Understanding hair morphology helps in analyzing hair types and addressing hair care needs.
