A hairbrush is a tool used for grooming hair. It typically consists of a handle and a head with bristles or teeth that help detangle and smooth hair. Hairbrushes come in various shapes and sizes, designed for different hair types and styles. Common materials for bristles include plastic, nylon, and natural fibers. Using a hairbrush can help maintain healthy hair by distributing natural oils from the scalp along the hair shaft. Regular brushing can also reduce knots and tangles, making hair easier to manage. Different types of hairbrushes, such as paddle brushes and round brushes, serve specific purposes in hairstyling.
