There’s something especially satisfying about being able to alter or enhance someone’s appearance in a way that increases her self-esteem and gives her an extra measure of confidence. Cosmetologists make it their business to understand how style and fashion can give people the self-confidence they need to perform their jobs effectively on a daily basis. The field of cosmetology encompasses many career paths, including hair styling, skin care, make-up design, manicuring, and laser treatments.
