Cosmetologists primarily shampoo, cut, and style hair, but they also perform a number of other services. These workers, who are often called hairstylists, may advise patrons on how to care for their hair, straighten or permanent wave a customer's hair, or lighten or darken hair color. Cosmetologists are licensed to provide all the services of barbers except shaving men. A growing number of workers in cosmetology offer specialized services. The largest and fastest growing of these is manicurists, who work exclusively on nails and provide manicures, pedicures, and nail extensions to clients.
Electrologists use an electrolysis machine to remove hair.
Finally, shampooers specialize in shampooing and conditioning patrons' hair in some larger salons. In addition to their work with customers, barbers and cosmetologists are expected to keep their work area clean and their hairdressing implements sanitized. They may make appointments and keep records of hair color and permanent wave formulas used by their regular patrons. A growing number also actively sell hair products and other cosmetic supplies. Barbers and cosmetologists who operate their own salons have managerial duties that include hiring, supervising, and firing workers, as well as keeping records and ordering supplies.
