Glossary Hair Composition

protein keratin, lipids, water, trace elements, and pigments

Hair composition refers to the various elements and structures that make up a strand of hair. Primarily, hair is composed of a protein called keratin, which provides strength and resilience. Additionally, hair contains lipids, water, trace elements, and pigments like melanin, which determine its color. Understanding hair composition is crucial for professionals in fields like dermatology and cosmetology, as it influences hair health, texture, and response to treatments.
