Black hair:

Black hair is caused by a great amount of eumelanin, so that the phaeomelanin is no longer visible. Black hair is by far the most frequent hair colour of the world and dominates almost everywhere except for Europe. It is the standard hair colour in almost all of Africa, South and East Asia, Australia, and America. Black hair appears in all textures ranging from very straight to kinky or peppercorn, and may be combined with all skin colours from pale to black. In some regions, especially Europe, North Africa, North and West Asia, as well as parts of Oceania and America, transitions to dark brown hair are common.
