Barbie dress up hair in the form of Barbie hair extensions and Barbie hair refills is available through several online retailers, including those of Amazon.com, Walgreens and Walmart. Some Barbies feature haircut and style themes with hair extension refill packs available for purchase if the model is still in production.
Various models of Barbie toys offer hair dress up features. Although the manufacturer has discontinued certain models, eBay and Etsy help shoppers find toys that are unavailable in stores because they're no longer in production.
As of 2015, the Designable Hair Extension Barbie is still in production, making designable hair extension refill packs easy to locate. Barbie designable hair extensions support inkjet printing directly onto the extensions.
