A comb is a tool used for grooming hair. It typically consists of a long, narrow piece of plastic, wood, or metal with a row of teeth along one edge. Combs help to detangle hair, style it, and keep it neat. They come in various sizes and designs, catering to different hair types and styling needs. Combs can also be used for other purposes, such as applying hair products or creating specific hairstyles. Some combs are designed for specific tasks, like fine-toothed combs for smoothing or wide-toothed combs for detangling. Overall, combs are essential tools in personal grooming.
