Fiber composition

Fiber composition refers to the types of fiber proteins that make up hair, showing how much of each type is present. Hair mainly contains keratin, a robust protein, but also includes other proteins in smaller amounts. The specific mix of these proteins influences hair's strength, elasticity, and texture. By analyzing the fiber composition, forensic experts can identify or compare hair samples, since each individual’s hair has a unique protein profile. This information helps in crime scene investigations and understanding hair's physical properties.
