Can I use sunscreen on my scalp?

What sunscreen can you use on your scalp?

Choose broad spectrum protection, which covers both UVA and UVB rays, and SPF 30 or higher. For a full day outdoors, choose SPF 50 or higher and water resistance. On UK labels, look for at least four star UVA protection; UVA inside a circle indicates that the product meets the EU standard.34

Gels suit hairy areas such as the scalp, where a cream has rather more hair to negotiate. Sticks can make application along a part easier. Powder or spray sunscreen can also be easier to apply through thinning hair. Oil free, water resistant products help limit sunscreen running into your eyes.125

For a sensitive scalp, choose a mineral sunscreen containing zinc oxide, titanium dioxide or both. Hair products advertised as providing UV protection are not a substitute for applying sunscreen directly to exposed scalp after your hair is dry.1

How do you apply sunscreen to your scalp?

1. 1Start with dry hair and dry skin. Apply before going outdoors, allowing 15 to 30 minutes rather than waiting until you are already in the sun.
2. 2Apply directly to the skin along your part, around your hairline and over thinning or bald areas. Cover exposed skin generously and evenly; a thin application reduces protection.
3. 3If you use a spray, apply enough for the skin to glisten, then rub it in for even coverage. Avoid inhaling the spray, never spray near your face or mouth, and keep it away from heat and flames.
4. 4Reapply about every two hours outdoors. Apply again straight after swimming, sweating or towel drying, and whenever sunscreen has rubbed off. Follow the bottle's directions.

Protect exposed scalp every day you will be outside, including cloudy days. A higher SPF does not extend the time between applications. Water resistant sunscreen also needs reapplication after swimming or sweating.5

Is a hat better than sunscreen?

A hat is usually the best protection for your scalp, especially one labelled UPF 50+, meaning ultraviolet protection factor. Choose a wide brim to shade your face, neck and ears as well. Use sunscreen on exposed areas when a hat is not practical, and seek shade rather than relying on sunscreen alone.134

When does your scalp need extra care?

Some dandruff shampoos, particularly those containing coal tar, make your scalp more sensitive to sunlight. Scalp sunburn can also increase flaking, so keep up protection while treating dandruff. Certain medicines and medical conditions also increase sensitivity to the sun.23

If your scalp burns, cool the skin with cool water and stay out of the sun until redness has gone. Seek medical help if you feel unwell or develop severe swelling or blisters. Include your scalp in monthly skin checks, and see a dermatologist promptly for anything new, changing or unusual.14
