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.
Yes, shaving one’s own head with clippers on a short setting is not hard to learn and do well. It’s incredibly convenient although it does limit what you can do with your hair. But the time saved is so wonderful.
