As you will readily note, the hair on a doll may be made from any number of things: from human hair, to synthetic fibers, to yarn and wool. Here’s a list of some common doll hair
types, and some specifics about them:
Caracul (and Wool)
Caracul is a short, curly fur, so named because of the origin of the fur being the Karakul sheep. The fur is also sometimes referred to as Persian lamb and is harvested from the skins
of newborn Karakul lambs. The fur was most often used as hair for baby dolls and for little boy dolls.
Human hair for dolls is precisely what it sounds like: hair from human heads that has been harvested after cutting or harvested specifically for the purpose of using it to make dolls.
The hair is nearly always woven into a mesh base to create a “wig” for the doll to wear. The wig is then glued to the scalp of the doll.
Mohair is the hair harvested from Angora goats. It is generally used identically to human hair since the two are similar in structure and consistency. They are also treated the same
way when it comes to care and styling.
Synthetic hair obviously refers to the synthetic fibers that are spun into shape to resemble human hair. Synthetic hair is probably the most common fiber used on more modern dolls. It
is generally attached to the doll using a wig base to which the synthetic hair is woven, or the hair is rooted into the dolls head in small clusters and glued into place from the inside.
Yarn hair is found on some older dolls that were generally mass-produced, as well as the soft-molded dolls of the late seventies and eighties “Adopt-a-Doll” craze. The yarn is usually
sewn or glued to the dolls head. The type of yarn ranges from coarser yarns used with the “adopted” variety and fine, thinner textures of yarn for older-model mass-produced dolls.
