Which ethnic group is known to have the thickest and coarsest hair?

The ethnic group that is known to have the thickest and coarsest hair is the Middle Eastern and Mediterranean population. This type of hair tends to have a wider diameter and a more oval or irregular cross-section, contributing to a coarser texture. The genetic factors that influence hair texture are diverse and the specific environmental adaptations in these regions have led to hair characteristics that are distinct from other ethnic groups.

In contrast, the other groups mentioned generally have different hair textures. African hair, for example, typically has a tightly curled structure, which can result in a finer appearance despite having a unique and complex texture. Asian hair is generally straight and tends to be smooth, with a round cross-section, making it generally thicker but not coarser in texture compared to that of the Middle Eastern and Mediterranean populations. Caucasian hair also varies widely but does not typically reach the same level of thickness and coarseness found in the hair of Middle Eastern and Mediterranean individuals.

This distinction underscores the biological diversity in hair characteristics among different ethnic groups, with the Middle Eastern and Mediterranean populations standing out for their thick and coarse hair.
