The Himba are an indigenous tribe of about 20,000 to 50,000 people living in the Kunene region of northern Namibia and on the other side of the Kunene River in Angola. The Himba wear little clothing, and the women are famous for covering themselves with otjize, a mixture of butter fat and ochre, possibly to protect themselves from the sun, which gives their skins a reddish tinge. Their hairstyle indicates age and social status. Children have two plaits of braided hair. From the onset of puberty the girls' plaits are moved over their eyes, and they can have more than two. Married women wear headdresses with many streams of braided hair, coloured and put in shape with otjize.
