We're used to seeing Katy Perry with a wilder look, but this simple jet-black 'do is just as striking! Here's how to style it:

1. Get your hair looking its healthy, natural best by indulging in a deep conditioning mask.

2. Spritz on a heat protection spray and use straigteners through the entire length of your hair.

3. To finish, and get your hair looking ultra sleek, use a good-quality shine serum.
