So, no, i most definitely wouldn't let a stylist do whatever they please with my hair. I always look for ways to change it up without sacrificing the length though. Sometimes, i think of cutting it off but i know, i'll regret it mid-haircut. It's easier for guys in that sense, whatever you do, you hair can grow back to normal within a year. I was growing out mine for years and years.
So, to Jack, Nick and Mathew, try going out of your comfort zone and if it doesn't work out, you'll be back to normal in a couple of months anyway but at least i'h tried something new. And about clothes, i don't see why you wouldn't try changing it up, if you want to. It's the least permanent change ever, just do it.
