A beauty supply is a store where people (usually females) go out and buy beauty supplys, see thats why its called a beauty supply!! :)(smile)! the "supply"s usually consist of hair products; such as hair gel (see pro-style gel, or scrunchies, or brushes,
combs etc... Or you can even buy hair
weaves for braids or regular
full head weaves. Or you can buy make-up, nail polish, or almost any thing else you can think of. Some of them even sell clothing. (usually only the more urban ones, like ones in urban cities, like oakland, or atlanta, or places like that).
