There aren't people regularly dying or winding up in the ER in states that don't require 10 months of expensive training to cut hair, so there is obviously a more reasonable line to draw.
A lot of the training is hands-on. It's a trade school. You're not spending a entire month studying the theory of scissors, you're spending a lot of that time working on many customers under supervision. Even a simple haircut for a man might take a professional 20 minutes. A more complex cut can take longer. A student can take twice as long as a professional. It all takes time. It's a lot of work. I don't know what you can cut out without reducing quality. The fact that all states have converged on similar requirements supports that.
