[...I'M over 50 AND have long hair.....
]

But I bet you look good!!
I'm over 50 also and when I was younger I used to have to curl my hair with those giant purple curlers & sit under the hair dryer for an hour. And don't dare even whisper the words "damp", "misty" or "rain" or my hair would curl & frizz right up. So in my early-mid 40's I finally started keeping it above my shoulders. Now that I have those 2 wonderful, amazing tools - blow dryer & flat iron, I don't think I'd look good with long hair. Most of the women I've seen with long hair who appear to be my age or older - and I really haven't seen that many, just don't look right. One woman I work with has very long, beautiful healthy hair but, I don't know, it just doesn't go with her age.
Maybe it's psychological, equating long hair with youth. Up until recently, I always looked younger than my age (I'm starting to look a little tired & haggard now) but I still didn't think I'd look good. Anyway, my hair grows so slow, I'll shrink a couple of inches before it has a chance to get long.
