The term "rough-haired" describes the texture of someone's hair that feels coarse and harsh to the touch. However, there may be times when one needs to use synonyms for this word. Some possible alternatives include "coarse," "bristly," "prickly," "shaggy," "unkempt," and "hirsute". These words can be used to describe the texture of hair as well as animal fur. "Unruly," "tangled," and "disheveled" are other words that can be used to describe hair that may be rough to the touch. By using these synonyms instead of repeating the same words, writers can add variety and richness to their language.
