In 1959, Mattel captivated little girls with a beautiful blue-eyed blond doll named Barbie. Over the years, this versatile doll has changed just about every aspect of her appearance, including her skin color, outfits, shoes, accessories and especially hairstyles. Many young girls still enjoy playing with and collecting this plastic doll. Once your daughter takes her out of the package, Barbie’s curls may become loose, giving her an unkempt appearance. If you want to curl her hair, don’t use a curling iron — her synthetic hair will melt.
