Some of the most common hairdressing courses cover aspects of hair cutting, hair styling, hair coloring, and the study of permanent waves and chemical straightening. Additionally, students customarily take preparation courses aimed at helping them pass formal board exams and licensing the successful graduates to do business in their respective states.
Hair cutting is commonly the most introductory course and trains students in the use of industry tools such as clippers, razors and scissors. Students learn the essential hairstyles for each gender, how to adjust styles to individual faces, and proper hygiene and sterilization practices. In coloring courses, students learn coloring theory, technique, mixing skills and safety. They also learn how to consult with clients and advise them on their options before the techniques are actually applied.
Hair styling courses are typically offered to intermediate and advanced students, and they focus on topics such as wet and dry techniques, thermal straightening, blowout styles and services for formal occasions, such as weddings and proms. In exam preparation courses, students are introduced to the requisite standards governing business practice and cosmetology in their states. They learn the statutes and laws applicable to their industry, and they may engage in sample written tests or mock practice situations aimed at evaluating their technical skills.
