Hair thinckness

There are many physiological and morphological characteristics in humans and some of them differentiate the populations. In addition to skin colour and facial features, hair morphology is one of the most characteristic and distinctive features in human populations. Comparative studies show that hair morphology is different between Asians, Europeans, and Africans. In the latter, the hair is more twisted while Asian hair has a thicker section than African and Caucasian hair.

The thickness of the hair depends on the size and shape of the hair follicles. Studies carried out to date suggest that only a small number of genes are involved in hair morphology, with the EDAR gene being one of the most strongly associated with Asian hair thickness.
