I think face shape has a lot to do with it, I have a longish face anyway, my dad's face shape rather than my mum's, and too long hair drags it down - shorter gives me much-needed cheekbones
Poll the fact that you wear it scraped up means you aren't getting the benefits of long hair anyway! Shorter would give it some shape and style....it needn't take a lot of styling every day, mine doesn't and I think Jo and Ally just wash and then quickly put it a bit of product and then they are fit to go
