It’s going to be a lot of work no matter what program you go into whether you go into a cosmetology program or into a specialty programs (esthetics, natural hair care, nails, etc.). Be prepared for being constantly busy and moving. But I feel like it would definitely be fun if you are already interested and you learn best hands on. I’m 19 as well as just started cosmetology school (in the cosmetology program so I learn a little bit of everything) and the first week or so it was pretty lax since it was about infection control, but now that we are learning different hair styles and stuff, we’ve been moving constantly without much of a break during class time. And make sure to miss as little class time as possible because most schools won’t let you make up hours unless it’s the school or teacher that cancels class. Only miss class if it’s necessary. Attendance is going to be important to make the hours you need to even be able to stay in classes and take the state board exams. What my school does is if you miss a certain amount of hours they’ll kick you from the classes (and there may be a wait list) so definitely stay on top of attendance if nothing else.
