I’m autistic, I’ve had one haircut since covid because I hate the sensory aspect of haircuts. I’ve been searching online of how to cut hair and it doesn’t look that hard, but a lot of people seem to advise against it. I think that if I fuck it up it’s not the end of the world, I can just go to a professional. But I have very long hair so I have a lot of opportunity for trial and error. I think that if I get some practice, it’s something I can continue to do going forward. I also don’t particularly care how it looks, I just want it to be shorter.
I buzz cut when I messed up practicing, but I keep my hair only just long enough to style slightly and only use powered trimmers really with a small pair of touch up scissors.
Buying a 360 degree mirror is my recommendation. It’s basically a swivel arm attached to three adjustable mirrors. Takes the blind guess work out of the equation and you can clean your neck up better.
