What does hair primarily consist of?

Hair primarily consists of protein, specifically a type of protein called keratin. Keratin is a fibrous protein that helps make up the structure of hair, providing strength and resilience. This is essential for the overall health and appearance of hair, as it undergoes various environmental and chemical factors that can affect its integrity.

While hair does contain a small amount of water, the predominant component is certainly protein. The presence of fat in hair is minimal and mainly related to the natural oils produced by the scalp, which help to maintain moisture and protect the hair. Carbohydrates are not a significant component of hair structure. Understanding the composition of hair is crucial for those in the field of barbering, as it informs various practices such as hair care, treatments, and styling methods.
