I was a Beauty School Student and I will give it to you straight.
As with every stylist you go to, you will find the good and the bad. Some students are good, some are awful and will never make it even if they eventually get their license.
Beauty School teaches you what you need to know to pass your state board exams. Most of what you need to know is theory. The exam itself will consist of a basic hair cut with shears and a razor. A manicure and probably some outdated things such as how to set the hair in rollers and pin curls and how to properly apply perm rods.
You answer questions on how to color the hair and might have to section it off for color, but you do not actually color the hair for your state boards.
When I went to Beauty School, I only did a few clients color. Instead, I preferred to be in the dispensary mixing the color for the other students to apply. There I learned how to achieve certain results with the color chosen.
Some of my teachers were very good and had worked in salons for years. Some never worked in a salon in their life. They just got their teachers license with no experience. You only need more hours of school to be a teacher and pass that exam.
As with anywhere you go, you could have a wonderful experience or a bad one. If you get a basic cut and color, you should be okay. If your cut is difficult and your hair color is very involved, you probably won’t be happy.
Then again. You could be thrilled. When you find a student that you like, that student won’t be there forever. They will graduate and move on and you will need to find someone else. Yes, you can follow them to their job, but it could be far away and might be months away. They have to pass the exam to work and the exam might be months after they graduate.
Maybe your coworker can recommend a certain student to your that she likes. That way you can be sure to get an experienced student stylist.
You might want to go in just for a manicure or a shampoo and blow dry to check it out first. That’s what I would do. Test the waters first and see how the clients look. You might also find a stylist that you would feel comfortable with to cut and color.
