Haircuts as an autistic person

So I’m really due a haircut. However, I find the entire experience to be a nightmare. I have really bad sensory issues when it comes to people or anything being near my head and the noises of the barbering stuff. I also find the small talk part difficult and struggle to explain to the barber how I want my hair done. Does anyone have any tips if they’ve had similar issues ? Trying to hype myself up to go on Thursday but it’s a struggle lol.
