A barber cuts hair and shaves and trims beards and mustaches. Barbers are similar to cosmetologists or beauticians, but they typically specialize in men's hair.
Barbers must have barber's licenses to practice their trade, according to HowStuffWorks. Most barbers attend school to learn their skills, but some learn the job through an apprenticeship. A test is typically required before the final license is granted. Requirements vary by state but usually include a written test with safety and skill information and a practical test in which the barber demonstrates his skill. A fee is required for the test and for the license. Periodic follow-up training is recommended.
