The Difference Between Hair Chalk & Hair Mascara?

It's official. Blonde is out. So is brown, red, and black hair, for that matter. Taking a cue from celebs, the hair colors to rock are either purple, pink, or blue for that "My Little Pony" look. Of course, if you're serious, you'll either have these colors on rotation, or multiple in your hair at once. Yes, Kelly Osbourne pretty much started the lavender hair thing years ago, but it's finally caught on. (Or come back, whichever way you want to look at it. This is another one of those fashion cycles.)

But since fads like hair-colors-not-found-in-nature tend to go as quickly as they come, and you might have to attend a job or school where you can't be so expressive with your love for color, there are some non-committal options to play My Little Pony for just a few days at a time.

• Hair Mascara: This is exactly what it sounds like; just brush the color through your hair and let it dry. This should come out after one shampoo.
• Hair Chalk: Rub this in your hair, and set with a flat iron. This should come out after a couple of days.
• Temporary Hair Dye: This works more like traditional hair dye, but will come out after a few washes.
