AG Hair Cosmetics runs routine surveys with a few hundred hairstylists to predict upcoming trends for hair. Looks like their predictions for 2007 hairstyle trends were pretty well spot on!

The most popular 2007 hairstyle trend to hit the runways and heads of celebrities is shaping up to be short cuts loaded with volume and "controlled messiness". This look transcends all age groups, and can look flattering on any woman. Slight variations make the style acceptable and fashionable for men, as well. You might think of it as the one size fits all approach to hairstyles!

Ellen Degeneres, Meg Ryan, and Hillary Clinton have already been seen wearing variations of the short and messy hairdo. This year will probably see the ladies adding more layers and volume to the roots of their hair, letting bangs fall over foreheads in a wispy- and slightly too long look that translates into a sexy framing of the face. If you just can't part with your long hair, remember to get rid of the super-straight locks that were popular last year. Adding a simple wave or loose curls will give you the fashionable look of the year.

The popular 2007 hairstyle trend for men is a simple to maintain, shaggy look. A good way to achieve this look is to have hair cut and textured into a short length. Wash and style hair before going to bed at night, and when you wake up simply run your fingers through and you're ready to go! It's the look that all fashionable men will be wearing for this year. In fact, if you want to take it a step further, men can add some warmer hair tones to their natural hair color.

While you don't want your hair to look or feel dirty, it's important to note that the current look of "controlled messiness" is managed better if your hair isn't washed every single day. Just-washed hair will also not hold as much volume as second-day washed hair, so keep that in mind and consider switching to an evening shower routine so you can keep up with the newest 2007 hairstyle trend.
