Students study the basic services haircutting, shaving, facial massaging, and hair and scalp treatments and, under supervision, practice on customers in school clinics. Most schools also teach unisex hairstyling and chemical styling. Students attend lectures on barber services, the use and care of instruments, sanitation and hygiene, and recognition of certain skin ailments. Instruction also is given in selling and general business practices. There are also advanced courses for experienced barbers in hairstyling, coloring, and the sale and service of hairpieces.
Most schools teach hairstyling of men's as well as women's hair.
After graduating from a training program, students can take the State licensing examination. The examination consists of a written test and, in some cases, a practical test of cosmetology skills. A few States include an oral examination in which the applicant is asked to explain the procedures he or she is following while taking the practical test. In some States, a separate examination is given for persons who want only a manicurist license or a facial care license. Persons who want to become barbers or cosmetologists must have finger dexterity and a sense of form and artistry.
