Growth for me is purely a curiosity, to see how long it will get. I can't even tell you how much growth I've had in the year since I've started, because I think I might have cut it at some point early on.
I WANT it to get long because it's fine and I've tried everything but really long; I'm wondering if the weight of length might help make it more manageable (plus I've lost some hair and longer helps me style and cover while it recovers). It's at armpit now and seems happy longer, so I'll let it keep going until it tuckers out.
If this is the best I can do? Cool; once I recover my thinned areas, I'll cut it. Short has its merits too! I guess I'm just easy like that.
