A hair brush is a tool used to groom and style hair. It typically consists of a handle and a head with bristles or teeth that help detangle hair, distribute natural oils, and create smooth styles. Hair brushes come in various shapes and sizes, designed for different hair types and styling needs. There are several types of hair brushes, including paddle brushes, round brushes, and vent brushes. Each type serves a specific purpose, such as straightening, curling, or adding volume. Regular use of a hair brush can promote healthy hair by reducing breakage and improving shine.
