The Active Girl's Guide to Beauty

WORKOUT WOE
Athlete's Foot
Athlete's foot is characterized by redness, itching, and burning, says Derick. The fungus grows in damp places, which is why it's often picked up when you go barefoot in locker rooms. Although experts aren't sure why, being affl icted once means you're more prone to pick up the fungus again.

Treat It
Over-the-counter Lamisil AT Cream ($16; drugstore .com) can reduce the symptoms within several days, says Derick.

Prevent It
Wearing flip-flops in gym showers or at the pool will help you steer clear of infection. Havaianas Slim Animals flip-flops ($24; havaianasus.com) are durable— and chic. For extra insurance, spray your soles and the insides of your gym shoes with antifungal Tinactin ($8; at drugstores).

WORKOUT WOE
Frayed Hair
Although a ponytail is the most practical workout do, it comes with a price: The elastic slides against your strands, causing tearing.

Treat It
A hair oil or protein mask can help put an end to breakage, says Eugene Toye, a stylist at the Rita Hazan salon in New York City. Smooth a tiny bit of either product under your elastic to keep your ponytail holder from rubbing. Toye likes Phyto Phytonectar Ultra Nourishing Oil Treatment ($30; beauty.com), with hydrating sunfl ower extract.

Prevent It
A fabric-covered scrunchie abrades hair less than an elastic. Try L. Erickson Ponies ($12 each; franceluxe.com).
