"Mini dolls with maxi hair!"
Teeny Teens were produced by Imaginations in 1988 and were a small series of little teenage dolls with long hair for styling. They are very hard to find.
"Wear them in your hair!"
There were eighteen dolls pictured on the back packaging, but they weren't necessarily sold as pictured. They had various coloured hair (blond, pink, red, yellow and blue), plus I've also found a black haired doll which isn't pictured below (although the dress is).
Each doll came with a brush and ribbon. Although each doll is differently dressed, none had names.
