To Bang or Not To Bang....In a non-Sexual Manner

My digital friends, I am getting my hair cut and colored tomorrow evening and I cannot, CAN NOT express to you how truly excited I am!!! It has been, THREE MONTHS, THREE ENTIRE MONTHS since I have had my hair done. The gray is a showing. The roots have probably 3 inches showing which makes them not so rooty anymore, and just more like "natural". And my BANGS are so long that I've already had to cut them myself. Plus, they are doing this weird, thinning thing. Not that my hair has ever been thick, but my bangs have pretty much always made a good showing on my forehead. Now they are whispy and it drives me crazy. Can your hair line change directions as you age? I mean beside moving backwards down the back of your head? Can it move SIDEWAYS??? My bangs are clumping in weird little clumps like they have never done before. So, I'm asking you, my digital friends, should I continue with the bangs or let them grow out al-aha Ugly Betty style?? Go in a new direction?? I have seriously considered going short again, but F freaks out every time I come back from the salon and my hair is shorter. I'm just so tired of having to put the effort in of styling it every morning. I'm feeling a sense of déjà vu, have I asked you this before??? My hair is so thin, or FINE as I was once corrected (again with the déjà vu) that if I try to do the bone straight no frills type of style it just looks flat and boring. There are a few women here in the office that can pull that look off, but I cannot.I would be happy with hair like these women:

But I just can't seem to pull it off. And another thing, I'm a tad clueless as to what my face shape is. Round maybe? Oval? Square? Heartshaped?? How am I to know?

Men have no idea just how easy they have it!!
