Winter-Proofing Your Skin, Hair, and Eyes

Flyaway Hair

How to prevent: Cold temperatures, wind, and excessive combing can create a buildup of negative ions on the hair shafts, which causes individual strands to repel one another, explains Roberta J. Hawk, a dermatologist in Billings, Montana. In a word: static. “Use a mild shampoo for dry hair, and always use conditioner, which gets rid of negative ions,” she says. Try Redken Smooth Down Shampoo ($10.50) and Conditioner ($12.50, redken.com for salon locations).

How to treat: River Lloyd, a hairstylist at the Peter Coppola Salon in New York City, suggests spraying Static Guard onto a hairbrush and brushing it through hair. “It always works,” he says.

When to see a professional: Flyaway hair accompanied by an itchy, flaky scalp indicates dandruff. If the condition doesn’t improve after you use an antidandruff shampoo like Head & Shoulders Classic Clean for two weeks, see a dermatologist.
