Well, we may not have flat irons in public bathrooms like they do the UK, but now, you can straighten your hair just about anywhere else with this awesome purse-sized Sephora Professional Cordless Straightener ($225). This 7-ounce flat iron is great for travel or a long night out, but just because it's small doesn't mean it can't pack a punch.

The high-end tool is made from ceramic, which is much better at smoothing cuticle than metal, and it warms up in under a minute with three different heat settings. It takes about three hours to fully charge and even comes with a car adapter, so you can recharge the battery in your car. Better yet, all this on-the-go straightening is safe: The Professional Cordless Straightener has a sensor to prevent overheating and an automatic shutoff after 30 minutes.
