What was the signature hair feature of Totally Hair Barbie, released in 1992?

Totally Hair Barbie's signature feature was exceptionally long, brushable hair.

Mattel released Totally Hair Barbie in 1992 with hair extending far beyond the length used on most earlier Barbie dolls. The central play idea was styling: children could brush, braid, decorate, and rearrange the unusually long hair with included accessories.

The doll became one of Barbie's best-selling releases and is frequently remembered as a defining fashion-and-beauty doll of the 1990s. Its appeal combined a bold visual silhouette with an activity that could be repeated without changing the doll's clothing.

Totally Hair Barbie is often confused with other long-haired dolls from the same decade, especially releases that used the words “long hair” or “hair.” The identifying feature here is the extreme length and styling emphasis. The doll's fashion was important, but the exceptionally long hair was the product's main selling point.
