When Rita Hazan started doing hair at age 17, she realized pretty quickly that UV protection for both the hair and scalp was vital to the now-famous color work she was doing. “It helps to prevent color fading and even frizz,” says the celeb hair colorist, who now has a world-famous Fifth Avenue salon and eponymous line. “I include it in all my products. It’s so important for maintaining color vibrancy and overall hair health.”
Cosmetic chemist Kelly Dobos also stresses how important it is, but is fast to admit it’s an area that is “hazy,” and a category that’s best described—no pun intended—in two parts: “The use of sunscreens in hair products can go one of two ways: hair protectant or actual scalp sunscreen. There’s some evidence that UVB rays can damage proteins in the cortex of hair, especially hair that is damaged. Sunscreen actives can also act as a color protectant, but are really not drug claims [because they are related to hair fibers, not skin], so these types of products usually don’t bother with the SPF testing, labeling and requirements, but just make some sort of UV-protection claim.”
Plus, Dobos says, the formulation of sunscreen for the scalp requires the same attention to detail as the skin-saving SPFs we apply to our face and body. “Sunscreen can be applied to areas of the scalp exposed by thinning or balding, and to the part. Avoiding peak hours of sun and wearing a hat are probably smarter ideas than buying a specific scalp sunscreen. Either way, it is always key to read the directions on sunscreens, no matter the formulation.”
Another important note: The FDA has actually not authorized sunscreen products in the form of wipes, towelettes, body washes or shampoos, which is why you don’t see SPF splashed all over hair products, at least in the U.S. “Powders are proposed to be eligible, but more data has been requested,” Dobos says. “In my opinion, it is unlikely a consumer will apply enough powdered sunscreen to achieve proper protection, whether the product is designed for the body or scalp. Powders may be useful for a touch-up, but I personally would not rely solely on them for sun protection.”
Montclair, NJ dermatologist Jeanine B. Downie, MD also points to some not-so-concrete regulation when it comes to sun protection for the scalp, and on a more serious note, says it’s a spot where skin cancer can most certainly happen. “I tell a lot of my patients to put a little bit of cream sunblock in their part area, and if they are bald, I have them use spray sunblock over their whole scalp.
Every single skin color needs sun protection—that’s not up for debate.—Dr. Downie
Likewise, Denver dermatologist Joel L. Cohen, MD says he, sadly, sees so many skin cancers on the scalp and ears every week.
“The concern with applying sunscreen to the scalp is always the inability to get good coverage in the area of hair,” Dr. Cohen explains. “Sometimes, people apply it to just the part line, but it’s still not consistent. Because of these reasons, it’s hard to do an actual clinical trial on scalp coverage—except in people who don’t have much hair, like men who may be quite bald.”
“Folks need to realize that they need protection on their scalp and ears on a daily basis—and better protection than simply trying to get a bit of sunscreen in their part,” Dr. Cohen adds. “As a dermatologist and skin-cancer Mohs surgeon, I recommend UPF [ultraviolet protection factor] for clothing and hats, not visors, which don’t protect the scalp. When it comes to the head, wearing actual hats—and preferably wide-brim hats that protect the ears, lateral cheeks and neck—is smart sun protection.
