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.
As a dude I go from long hair to slightly-less-long hair by cutting it on each side above the shoulders. Pulled forward below the neck if long enough, sort of like the opposite of the unicorn trick (tried that in the past, but easy to mess up the layering).
Also probably makes more sense if you usually keep your hair in a ponytail, as any imbalance won’t be obvious.
