Run local models.

Well, if you have a lot of hair to play around with, you can just try it without much risk. I cut my own hair (male, short hair) but I find it really difficult to manipulate scissors or clippers while looking in the mirror. I also can’t really do the back of my head so I have to get someone to help me.

Just be ready to clean up, because hair will fly all over the place if you aren’t careful.
