SPF Protection Level
No matter your skin type, it's best to opt for the highest SPF level when purchasing sunscreen for your head. The sun damage caused by ultraviolet (UV) rays is cumulative, meaning it adds up over time. This includes exposure to both UVA and UVB rays. While UVA rays cause damage deeper in the skin cells, resulting in visible aging such as wrinkles, UVB rays target the surface-level cells. Look for a sunscreen that offers the highest level of broad-spectrum protection from both UVA and UVB rays.
Sunscreen for your head should be lightweight, non-greasy, and fast-absorbing. This helps to ensure that the product doesn't interfere with styling efforts, and is able to protect you from further damage. Look for a formula that's chock-full of natural ingredients and rich antioxidants, such as niacinamide, green tea extract, coffee extract, licorice root extract, microalgae extract, as well as safflower seed oil and green tea oil. Protecting your scalp should not come at the expense of stifling your hair.
A good sunscreen should not only protect your scalp from damage, but should also address a common issue often linked to scalp damage: thinning hair. Look for a sunscreen that includes technology that adds volume and lift in addition to providing sun protection. This will help to keep your hair looking full and healthy, no matter how often you’re exposing your scalp to the outdoors.
Reapplying sunscreen is just as important as applying it in the first place. It's important to be sure to apply your sunscreen every couple of hours, especially after being exposed to water. While SPF ratings of 30-50 are generally enough for most people, those living in Texas may need to look for an even higher rating.
People who subject their hair to treatments such as bleaching, coloring, relaxing, or perming should keep in mind that scalp and hair sunscreen products can interfere with the effectiveness of the treatments. Make sure to read the product label instructions in detail before using.
