Are you a long-hair-for-life girl or have you switched it around? Did you cut it short once and then never have it long again (or grew it ASAP and never cut it short again?)
I'm 48, with pretty straight boring light-brown hair. Was quite a tomboy kid and had long hair until I was 6 or 7, when I got a chin length bob with a fringe. Then aged about 8 had it cropped really short, which I loved and it basically remained that way much of the time until I was nearly 35.
I did grow it to my shoulders aged 13-16 when I didn't fit in at secondary with all the super girly girls, but hair didn't make any difference and at around 16 I cropped it again having found my friend group and myself. In 6th form I bleached it. End of A-levels I bleached and dyed it pink, uni I had it either cropped or in a very short bob, bleached it with dip-dye pink just after I left uni. It was also bleached and blue at one point.
Then cropped it again and variously had dark red bob/bowl cut with thick bleach streaks (when that sort of thing was a thing for a bit) cropped and dyed it ginger, had purple extensions sticking out at the back, dark purple all over (as it was when I met now DH), crop, grown out crop (which I had when I married). Got a short bob after I was married, cropped before I had my kids and dyed my fringe pink during second mat leave.
Then bobbed and finally grew it out and had long hair for the first time in my adult life aged 36-45. Never really knew what to do with it, though - it was a ponytail or a messy bun, everything else was far too complicated for me!
3 years ago, cut to chin length bob with undercut on one side when I decided I wanted to have short hair again - next haircut going to change again and get it shorter with more visible undercut.
