However, your hair can change its color by chemically treating it with drugs or coloring agents. For example, some blue-black pigments used in tattoos are derived from chemicals found in black hair dye. There are also natural ways to change the color of your hair; for example, red hairs appear when a person has been drinking red wine or eating cherries. However, these changes only last about one week once you stop eating fruit or drinking wine. People of African descent are more likely to be born with black hair than others because they have more opportunities to pass down this trait through reproduction. This is due to the fact that people with black hair are able to attract mates more easily than those with other colors of hair. In addition, there are several diseases associated with black hair including albinism and vitiligo.
