Formal training programs include classroom study, demonstrations, and practical work. Most schools also teach unisex hairstyling and chemical styling. Students attend lectures on barber services, the use and care of instruments, sanitation and hygiene, basic anatomy, and recognition of certain skin ailments. Instruction also is provided in sales 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 many States, cosmetology training may be credited towards a barbering license, and vice versa. A few States have even combined the two licenses into one hair styling license.
