A hair clipper is a handheld electric device used for cutting hair. It typically features a set of sharp blades that move back and forth to trim hair to various lengths. Hair clippers are commonly used by barbers and individuals for home grooming, making it easier to maintain hairstyles without the need for scissors. Most hair clippers come with adjustable guards or attachments that allow users to choose different hair lengths. They are designed for both dry and wet hair, and some models are cordless for added convenience. Regular maintenance, such as cleaning and oiling the blades, ensures optimal performance and longevity.
