Hairstylist → It is formed from "hair" (from Old English *haer*, meaning the fine strands growing from the skin of humans and animals) and "stylist" (from Greek *stylos*, meaning pillar or support, and the suffix "-ist" meaning one who practices or specializes in). The word "hairstylist" refers to a person who specializes in styling hair.
Think of someone who specializes in working with 'hair' and is a 'stylist' — that's why a hairstylist is someone who styles hair.
