Having had the cut for a while and now beginning the process of growing it out in order to be prepared for moving overseas and being out of range of salons that I trust, I figured I'd throw out some of what I've learned.
1. Push it forward.
I've seen a few girls get the short cut and then comb it down as if it's a man cut, and then they hate it and grow it out as soon as they can. To rock a pixie cut, you need to be pushing it all towards your face. This is crucial. Pushing it forward is what makes it look sexy and modern. Case in point - see how the hair is not pushed back and down, but forward, except the bangs?
2. Leave yourself bangs and push them to the side.
This makes it look feminine. When it gets longer, you'll have to pin the bangs back (at least if you have hair like mine). I sort of like mine right now, though, because it gives a little flippy interesting bit on one side that I'm okay with for a while.
*update - I have now tried it with and without bangs, and really, it's been fine both ways!
3. Don't be afraid to cut it short.
When I first got it cut I asked them to leave it a little longer and shaggy, and I didn't know how to style it and it didn't look right. When I was brave enough to let them just really pixie cut it short, I loved it and it was so much easier to take care of. Over time when I grew it longer, I found different ways to style every stage in a way that I liked, which surprised me.
4. Use product.
If you cut it really sort, use hair wax. You need to keep it from becoming a poof, and hair wax isn't as much of a wet look while still letting you sculpt it. Good hair wax is harder to find, but over the last month as I've started to let it grow out I've been using light (and cheap) mousse. It takes a poofy mess and gives it sleek shape.
5. If it's unmanageable, blow-dry it.
One of the things I've loved about short hair is that I don't have to spend much time styling it. I didn't blow dry it for six months. This month, however, I've let it get longer and to manage the increased volume (my hair is so thick) I've started blow drying it again. I wish I'd started earlier whenever I felt like it was getting poofy. It makes it sleek and manageable.
Short hair grows fast and so what looks great for a couple of weeks might not look great two weeks later. I chose to keep the hair on the side long so that I either have to push it forward so it's brushing into my face, sweep it back over my ears, or tuck it back behind my ears. Each one is a different look. Use bobby pins, try curling the edges, buy fun headbands...
