A hair razor comb, also known as a razor comb, is a grooming tool that combines the functions of a hairbrush and a razor. It features sharp teeth that are designed to cut and thin hair as it is combed.
Hair razor combs have gained popularity for their ability to remove split ends, reduce hair volume, and create a textured, layered look. Historically, they have been used by barbers and hair stylists to achieve specific styles and textures.
