Let's say you went on a beach vacay, decided it'd be fun to get cornrows (à la Bo Derek in the Acapulco-based film 10), and then get home to realize you have no clue how to care for them. Shampooing, conditioning, or adding your traditional product to the newly braided part can result in flakes no matter how well it's rinsed out, especially if they're only on a small section of your head.Take my tip from a pal with dreadlocks – use that canned air ($5) traditionally meant to clean computers to keep your hair flake free. Since it comes with a fine straw, you can get into the tiny crevices and blow the air through to remove dust and debris. Word to the wise: don't stay on one section too long because the icy air can freeze hair. . .and probably wait 'til your coworkers are gone for the day to avoid some crazy looks (wink wink).
