For more casual days I've been loving a high ponytail, I leave my parting showing instead of scraping it all back and leave a few pieces flowing free at the front. I'm not overly careful when pulling it up into a high position which gives a lot of height at the crown. After securing it tightly I pull at the roots around the front of my hairline which gives a little more body to the sides, before popping hair slides all over the gaff to keep the body and height. When I want things to look slightly more pulled together (only slightly, it's still a messy ponytail after all) then I opt for a low pony tail with loose pieces around the face a little backcombing for lift and, again, a lot of hair slides. This style in particular is one I don't think I've ever been drawn to before, but with shorter hair I've been loving it!
With both styles I've been using my Oribe Maximista Thickening Spray before styling. A quick blast with the hairdryer later and (I feel like) I've got a lot more hair to play with. I also love using texturising sprays when I'm pulling my hair back, as they tend to give my hair a lot more grip which helps make the styling process much easier. I normally use the Bumble and Bumble DrySpun Finishing Spray*, but recently I've been using their City Swept Finishing Spray*(which you can get here if you're US based) instead as it works much better with my hair type - keep your eyes peeled for this one, it's a goodie.
