I have yet to be able to sit for a proper haircut since the assault, either. Same problem, can't stand ANYONE near my head or hair.

I've gone so far as to just do it myself anymore these days. Store-bought clippers and good to go since I pretty much keep it like I had it in uniform anyway, nothing fancy needed.

If it's specifically a male stylist, have you tried maybe approaching a place with a female stylist? Just a thought...
