    GlossaryHair Shaft (hair surface)

    visible part of hair extending above the skin's surface

    The hair shaft is the visible part of the hair that extends above the skin's surface. It is composed of three layers: the cuticle (outer layer), the cortex (middle layer), and the medulla (inner layer). The hair shaft is primarily made of keratin, a protein that provides strength and resilience. Understanding the structure of the hair shaft is crucial for professionals in dermatology and cosmetology, as it influences hair health, texture, and response to treatments.
