Although it may be hard to reach your actual scalp if your hair is in the way, you can apply sunblock to your scalp, especially the part in your hair. "Use a small amount of your regular spray or lotion sunblock and gently massage into the surface of the scalp, trying to avoid as much of hair as possible," Dr. Radusky said. "Zinc and titanium physical blocks are OK but can leave a white residue."
He recommends Banana Boat Sport Quik Dri Spray Sunscreen ($11) because it works well, is approved by the Skin Cancer Foundation, and dries fast without leaving your hair greasy.
