A hair stylist is a trained beauty professional who is skilled in cutting, processing, and styling hair. Hair stylists discuss with clients what kind of cut they want and their desired look, and you recommend products and services to achieve it. You may also advise the customer of different haircuts that may work better with their type of hair or may be more flattering with their face shape. Some of the services that a hair stylist offers include cutting, coloring, curling or straightening, and treating hair. Hair stylists typically attend conventions and training sessions to learn new methods and techniques for current styles and trends.
