There are maybe more descriptors for various kinds of hair and hairiness than any other word-set in English, and some of them are extremely strange and fun. The more pedestrian terms like shaggy, unshorn, bushy, coiffed, and so on we’ll figure you already know. The adj. barbigerous is an extremely uptown synonym for bearded. Cirrose and cirrous, from the Latin cirrus meaning “curl” or “fringe” (as in cirrus clouds), can both be used to refer to somebody’s curly or tufty or wispy/feathery hair — Nicolas Cage’s hair in Adaptation is cirrose. Crinite means “hairy or possessed of a hair-like appendage”, though it’s mainly a botanical term and would be a bit eccentric applied to a person. Crinose, though, is a people-adj. that means “having a lot of hair”, especially in the sense of one’s hair being really long. The related noun crinosity is antiquated but not obsolete and can be used to refer to somebody’s hair in an amusingly donnish way, as in Madonna’s normally platinum crinosity is now a maternal brown. Glabrous, which is the loveliest of all hair-related adjectives, means having no hair (on a given part) at all. Please note that glabrous means more baby’s-bottom-hairless than bald or shaved, though if you wanted to describe a bald person in an ironically fancy way you could talk about his glabrous dome or something. Hirsute is probably the most familiar upmarket synonym for hairy, totally at home in any kind of formal writing. Like that of many hair-related adjectives, hirsute’s original use was in botany (where it means “covered with coarse or bristly hairs”), but in regular usage its definition is much more general. Hispid means “covered with stiff or rough little hairs” and could apply to a military pate or unshaved jaw. Hispidulous is mainly just a puffed-up form of hispid and should be avoided. Lanate and lanated mean “having or being composed of woolly hairs”. A prettier and slightly more familiar way to describe woolly hair is with the adjective flocculent. (There’s also floccose, but this is used mainly of odd little hairy fruits like kiwi and quince.) Then there are the pil-based words, all derived from the Latin pilus (= hair). Pilose, another fairly common adj., means “covered with fine soft hair”. Last but not least is the noun pilimiction, which names a hopefully very rare medical disorder “in which piliform or hair-like bodies are passed in the urine”. Outside of maybe describing some kind of terribly excruciated facial expression as pilimictive, however, it’s hard to imagine a mainstream use for pilimiction. Tomentose means “covered with dense little matted hairs” — baby chimps, hobbits’ feet and Robin Williams are all tomentose. Ulotrichous, which is properly classed with lannate and flocculent, is an old term for “crisply woolly hair”. Be advised that it is also, if not exactly a racist adj., certainly a racial one — AC Haddon’s Races of Man, from the early 1900s, classified races according to three basic hair types: leiotrichous (straight), cymotrichous (wavy) and ulotrichous.
