According to Doctor Anne, a scalp and hair sunscreen is legit when it contains ingredients that are good at binding to the hair and have been proven to deflect UV rays.

Opt for a zinc-based formula without titanium dioxide, which can harm hair. Use a “broad-spectrum” and water-resistant sunscreen with an SPF of at least 30.

SPF lotions are a good option for those who are bald, but they are less effective on heads covered in hair. To avoid greasy buildup in your hair from lotion, use a stick or spray.

Compared to lotion, sticks and sprays are more lightweight and convenient. They absorb quickly, can be applied directly to your hairline, and are easy to reapply.

Sunscreen powder sprays are lightweight and absorb easily, doubling as a dry shampoo. They hydrate the hair while simultaneously protecting it from UVA and UVB rays.

Choose a powder spray that also works well on the face. Oily scalps benefit from matte finishes while hydrating sunscreen sprays should be used for dry scalps.

Spritz sunscreen sprays on your scalp to the ends of your hair and spread it with a brush or comb. For powder sprays, spritz 8 inches from your roots and massage it around.

With a powder spray, spritz 8 inches from your hair roots and massage it around, and for gel or lotion, apply it like a hair lotion. Apply 15 to 30 minutes before sun exposure.
