A black plastic
comb. Toothed devices used for styling, cleaning and managing
hair and
scalp, combs have been used since
prehistoric times, and examples date back to 5,000 years. Combs vary in shape according to function, and can be made out of a number of materials. Most combs are
plastic, metal, or
wood;
ivory combs were also once common.
