After completing high school, you'll need to:
* Complete a cosmetology or hairdressing program: These programs are offered at vocational schools, community colleges, and sometimes private academies. The length and specific curriculum will vary.
* Pass a state licensing exam: Once you finish your program, you must pass a state-administered licensing exam to legally practice as a hairdresser in that jurisdiction. Passing this exam is the crucial step, not specific high school grades.
In short, focus on completing high school and then successfully completing an accredited cosmetology program and passing the licensing exam. Your high school GPA is less important than your performance in the professional program.
