A hairbrush is a grooming tool designed to detangle, smooth, and style the hair. It typically consists of bristles or teeth that are evenly spaced on a handle, allowing for easy and comfortable use. Hairbrushes come in various sizes, shapes, and materials to cater to different hair types and styling needs. They help distribute natural oils from the scalp throughout the hair, promote blood circulation, and remove loose hair and debris. Hairbrushes are essential for maintaining healthy hair, reducing tangles, and achieving desired hairstyles with ease.
