✔️ Go wide: Not all sun hats are created equal. “Generally, a 4-inch brim around the entire circumference of the hat is needed to protect the face, neck, eyes, and ears,” says Dr. Waldorf. Visors can also be worn for protection from the sun, but the brim should be very wide, practically wrapping around the head, she adds.
You will also want to avoid baseball caps unless they have a drape. “An ordinary baseball cap isn’t enough – it’s designed to protect your eyes from sun glare, not to protect your skin,” Dr. Waldorf notes.
✔️ Pay attention to the color: When it comes to fabric, opt for hats with a dark-colored, tightly woven fabric like denim, canvas, wool or synthetic fibers, which can effectively protect against harmful UV rays, depending on the skin cancer foundation. To check fabric coverage, shine a flashlight through it to see which areas are shaded and which are exposed, suggests Debra Jaliman, MDa New York-based board-certified dermatologist and author of skin rules. If you can see through the fabric, UV rays can reach your skin.
✔️ Scan the label: There are hats with built-in UV protection, which can make shopping a little easier. Opt for hats that have an ultraviolet protection factor (UPF) of 30 or higher, says Dr. Jaliman.
