If you are interested in a career in hair styling, you may need a state-accredited license in order to become a professional hairstylist and exercise in a hair salon. At hairstyling schools, you have the option to take courses besides the basics for hairstyling (hair shampooing, hair coloring, hair cutting, hair design); i.e. you may also specialize in cosmetology or become a barber. In the end of your professional hair care training, you may required to take a written, oral and a practical exam about professional hair styling. With a hair styling certificate, you might become self-employed and open your own professional hairstyling salon. If you have already a degree as a professional salon technician, you should still consider attending regular training classes about hair design and hair style in order to be in tune with the current hair trends.
