10 Skin Cancer Mistakes Even Smart Women Make

9. Scalp and Hair Protection

The Mistake: You can't stand how you look in a hat.

That means your scalp is at risk. Sure, your hair offers some protection (more if it's thick), but your part is likely to get fried. Rub sunscreen into exposed areas, advises Dr. Northington. Keep in mind, however, that a hat with a brim all the way around is the best defense, says Dr. Rigel. "For every inch of brim, you reduce your lifetime risk of skin cancer by 10 percent," he explains.

Don't Fry Your Hair!

Spend the day outside without turning your locks to straw, thanks to a new arsenal of products that shield hair from harsh UV rays. Phyto Plage Protective Sun Veil ($20), Samy Colorcare Protecting Spray ($5.99), and Redken UV Rescue Recovery Treat ($14.95) banish brittleness and leave tresses soft and shiny.
