A hair comb is a grooming tool used to untangle and style hair. It typically consists of a long, narrow piece of plastic, wood, or metal with a row of teeth along one edge. Combs come in various sizes and designs, making them suitable for different hair types and styles. Combs can be used for both wet and dry hair, helping to distribute natural oils and remove knots. They are often used in conjunction with other hair care products, such as hairbrushes and hair gels, to achieve desired looks. Regular use of a comb can promote healthier hair by minimizing breakage.
