• Even though the first black Barbie debuted in the '60s, she's finally just now getting a hair update. Sort of. The online doll maker Natural Girls United, takes existing dolls and gives them afros, braids and bandu knots, to better reflect real womens' hair. "I see people walking around with gorgeous hairstyles that inspire me," said company founder and doll designer Karen Byrd. Byrd said she loved Barbie, but said she "always noticed that my African American dolls did not look like me. If a child is constantly looking at images, dolls, television, books and magazines and only seeing beauty as something or someone with non-ethnic features and long, straight hair -- then they are going to assume that this is what beauty is. It is something that has hurt our young people for centuries." The custom designs retail for between $40 and $140. [Shine]
