In the US, you need to complete a licensed cosmetology program to become a Hairdresser. These programs have minimal entry requirements other than a high school diploma or an equivalency like the GED. 

To find a licensed program in your area, the American Association of Cosmetology Schools has a helpful database that allows you to search for schools in your area. If hairstyling is your main passion, you should look for a school that focuses on hair. 

In your hairstyling program, you will learn theories such as hair cutting, styling, color theory, chemical restructuring (i.e., perms and relaxers), and hair dye application. Students often practice on mannequins until their instructor allows them to start doing free or low-cost haircuts under the supervision of an experienced Hairdresser. 

Once you complete your program, your state may require you to pass a written and possibly even a practical test to become a licensed Hairdresser. Written tests usually focus on sanitation and safety, while the practical test requires you to demonstrate some basic skills. Research your state requirements to make sure you prepare adequately for the test if need be. 

Important things to know before becoming a Hairdresser

• It's a physically demanding job.

Being a Hairdresser means standing for long periods, which can have repercussions on your body. Your feet, back, arms, and legs can all get sore. Make sure you wear appropriate footwear and maintain a good posture when working. Beauty school does help with teaching good ergonomics. 

• It can be a volatile industry.

The mechanics of a good and bad economy affect almost all workers, especially those who work in personal care industries like hairstyling. Many people will skimp on hairstyling and nail care services if the economy is doing poorly to save money. This leaves you as a Hairdresser with free appointment slots and an inconsistent income. There are also seasonal fluctuations in demand for hairstyling services, so learning those fluctuations and setting money aside will help you feel more in control of your financial situation.

• It takes time to build a client base.

When you're just starting, you might not be fully booked. You need to work at developing your client relationships, ask clients to refer you to friends. Many Hairdressers also post regularly to social media, which acts as a portfolio of their work. This can be a slow process, and patience is key.
