Can you become a hairdresser when graduate out of high school?

You can't become a fully licensed hairdresser immediately after graduating high school, but you can start the process. You'll need to attend cosmetology school (or a similar program) to receive the necessary training and then pass a state licensing exam. The length of cosmetology school varies by state, but it's typically around 1,500 hours of training. So, while you can begin your journey to becoming a hairdresser after high school, it takes additional education and licensing before you can practice professionally.
