At Darling Buds we have a long experience of hair transplant in different ethnic groups- Caucasians, Africans, East Asians, Arabs, and ofcourse South Asian

African hair is curly and looks dense and bushy. But it does not have the same density as other racial groups simply for the reason that one hair does the work of 10 hairs- the purpose of hair is to regulate body temperature and additionally, though less importantly, is a secondary sexual characteristic in humans.However, today man controls his environment so the he latter function weighs heavily on the minds of bald people today when they seek hair transplant.
Africans have curly hair for a reason. They are situated alongside the equator and the burning heat on a dark scalp is offset by a layer of thick curly gravity defying hair that forms an insulation of sorts by retaining relatively cooler air and preventing heat reaching the brain. The air is cooler here since evaporating sweat retained in hair zone causes cooling. You will never see an African full head of hair dripping sweat even in the warmest of climates unlike other races where the hair drips sweat.
