The main component of hair is keratin, which is a fibrous protein that forms the structural foundation of hair strands. This protein is also found in other parts of the body, such as nails and the outer layer of skin. Keratin is crucial in providing strength, durability, and protection to hair, making it resistant to various environmental factors and chemical treatments. Its unique properties allow hair to maintain its shape and resilience while also reflecting light, which contributes to the hair's overall appearance. Understanding the role of keratin in hair structure is fundamental for anyone studying cosmetology, as it influences hair care practices and product formulations aimed at maintaining healthy hair.
