Regular haircuts are one of the mainstays of basic grooming, but barber and salon visits can become quite costly, especially for people with short hair that requires frequent trimming and shaping to stay neat and clean-looking. Many men eventually opt to purchase a hair trimmer that they can use at home instead. A lot of people associate an electric trimmer with shaved heads and military buzz cuts, but with the right skill and attachments, a variety of short, layered haircuts can be achieved with this useful tool. Families often have a clipper or trimmer on hand to do at-home cuts for kids, and even women with short hairstyles can make use of a hair trimmer, particularly for cleaning up the neck. Professionals who own their own barber shops or salons should also purchase a quality hair trimmer, but this guide focuses primarily on what to look for when buying a hair trimmer to use at home.
