What is hair primarily composed of?

Carbohydrates
Fats
Protein
Minerals

The correct answer is: Protein

Hair is primarily composed of protein, specifically a type of protein called keratin. Keratin is a fibrous structural protein that plays a crucial role in the composition of hair, nails, and the outer layer of skin. This protein gives hair its strength, resilience, and overall structure. Understanding the protein composition of hair is essential for barbers and stylists, as it influences how hair behaves and how it should be cared for or styled. While carbohydrates, fats, and minerals are important components of a balanced diet and can impact overall hair health, they are not the primary building blocks of hair itself. Carbohydrates can provide energy, fats can aid in moisture and texture, and minerals contribute to hair health, but the actual structure of hair relies fundamentally on protein.
