1. Your scalp
Wide-brimmed hats and baseball caps can easily set sail on a strong summer’s breeze, so make sure that your scalp is protected with sunscreen along the hairline and parting. “People who have their hair parted always miss that spot,” says dermatologist Julia Carroll, MD. “And guys who are losing their hair and thinning on top, they need sunscreen there too.” Carroll understands that people might be hesitant to apply a greasy sunscreen in their hair, so she suggests using a spray sunscreen instead. Sprays penetrate through the hair and don’t usually leave an oily residue.
