Hair clippers are electric or manual tools used for cutting hair. They consist of a set of sharp blades that move back and forth to trim hair to a desired length. Many clippers come with adjustable guards, allowing users to choose different lengths for various styles. These devices are commonly used in barbershops and salons, as well as for personal grooming at home. Hair clippers are popular for their efficiency and ease of use, making them a preferred choice for maintaining short hairstyles and performing quick touch-ups.
