If you tend to neglect your scalp when it comes to sun protection, it's time to invest in a hair-friendly sunscreen to give you the motivation you need. The best hair sunscreens have lightweight, non-drippy formulas and offer an SPF of at least 30, as advised by the American Academy of Dermatology, and are water resistant for up to 80 minutes. Plus, they won't completely mess with your hair and are designed to make reapplication effortless.
As with any sunscreen, plan to reapply your hair (or scalp) sunscreen every two hours, or more often if you’ve been sweating or swimming. When using a spray or mist on your scalp, be careful not to spray the product into your eyes or face. If you have a hard time with the idea of using a lot of liquid sunscreen in your hair, you can buy a powder sunscreen as a backup option to use on top of your spray or cream sunscreen. These powder formulas can be especially handy for midday touchups, but note that they shouldn't be used as your sole form of sun protection, as they tend to be less effective. Also — and this may seem obvious — but if you're concerned about keeping your scalp protected from the sun, invest in a hat with UPF sun protection.
