Getting sunburnt is essentially a summer rite of passage, and your typical sunscreen usually poses a solution when used correctly. (Yes, that means you need to reapply!) But while you’re slathering your body in a pasty white lotion or sticky spray to prevent burns and hyperpigmentation (like melasma), the easiest spot to miss is your scalp. Enter: Hair sunscreen, formulated to protect your scalp and tresses from the sun's damaging rays.
Why you need to apply sunscreen on your scalp
Because your scalp is the highest point of your body, it makes first contact with the sun, receiving direct ultraviolet radiation—meaning, it tends to burn more easily than the rest of your body. Plus, the likelihood that you are applying SPF to your scalp or hairline is probably slim to none, because who wants greasy strands anyway?
The bad news: Research shows that scalp melanomas, a form of skin cancer, exist and can be especially dangerous if found too late, giving you yet another reason to give your scalp some cover. While skin cancer of the scalp is not as common as skin cancer on other areas of the body, it’s usually diagnosed at a later stage (which can be lethal) due to your hair hiding it, Debra Jaliman, MD, a New York-based dermatologist, previously told ishonest.
And if you have a full, thick hair, you might assume you're in the clear, but think again. “Even if you have a full head of hair, your scalp is at risk for a sunburn,” Arielle Nagler, MD, a dermatologist at NYU Langone Medical Center, in New York City, told ishonest in an interview. Sure, those who are balding, patchy up top, or have thinning hair are more at risk of developing skin cancer on the scalp, but the same safety measures need to be taken for everyone, since hairlines and parts can burn easily, Dr. Jaliman previously told ishonest.
Why you should put it on your hair, too
So you obviously need to protect your scalp, but don't forget that your actual hair is also at risk of becoming dry and brittle from UV rays. Sun exposure can result in cuticle damage (translation: it can destroy the outer cover of each hair strand), according to Cleveland Clinic. Not to mention, sun damage can come in the form of split ends, frizz, discoloration, and thinning hair, similar to what you’d get with heat damage from your favorite curler or flatiron. Yikes. Even more reason to protect your hair with SPF, or—at the very least—a hat.
Finding a hair sunscreen that you like enough to use consistently is key. If you buy something that just makes your strands an oily mess, chances are, you're going to leave it at the bottom of your beach bag or toss it in the trash. Opt for sunscreen powders, which will soak up grease and won't cause any unwanted buildup. Mousse formulas can be applied to the hair and scalp, and are surprisingly less oily than more traditional sunscreens, Dr. Jaliman told ishonest in an interview. Finally, be careful when using spray sunscreens on your scalp and hair, since many times more of the product ends up in the air than on your skin.
