Q
Why do we have different hair textures?
A
Expert Answer
Hair texture (straight, wavy, curly, coily) is determined by follicle shape and the distribution of keratin proteins. Round follicles produce straight hair; oval follicles produce curly hair. Genetic factors (EDAR, TCHH genes) and evolutionary adaptations to climate influenced texture variation.
