Can you cut your own hairs

I've only ever tried to cut my own hair once, and it was when I was on a manic high. What a bad idea. I have discovered, though, that whenever I get the urge to cut my own hair, it means a manic episode is on the way, and it's time to adjust my meds. So despite the bad haircut, I learned something valuable.

I'll need a salonist or something. I've never tried to give myselfa haircut before, and I don't think I can!

y not?
