Unlock the Secret to Flawless Hair: The 6 Scalp Sunscreens Dermatologists Swear By in 2026—Are You Missing Out?

Ever wondered if there’s a sunscreen out there that actually won’t wreck your hairdo while keeping your scalp safe? Yeah, me too — and let me tell you, Brush on Block isn’t just another pretty face in the sunscreen aisle. Dropping $36 might make you do a double-take, but this powder sunscreen is like a tiny miracle in a tube. Fluffy, soft brush bristles that glide on smoother than butter, plus a clever twist-lock design that keeps the powder in place—even when you forget to lock it up. And for us eco-conscious folks, it’s refillable, saving some green while cutting down plastic waste. Packed with zinc oxide, hydrating goodies like hyaluronic acid and jojoba, and even vitamin C to brighten those stubborn discolorations—this thing means business. Plus, it’s water-resistant for a sweaty workout or a beach day, without killing your style. Dermatologist Hadley King, MD, raves about it too – calling it the ultimate scalp protector, and bonus, it doubles as a dry shampoo. If you’re serious about scalp sun protection but hate the greasy, white-cast nonsense, this might just be your new holy grail. Ready to see why it’s worth the hype? LEARN MORE

Sure, spending $36 for sunscreen might seem like a splurge, but Brush on Block is totally worth the investment. I’ve been using this sunscreen for years and can attest that it’s one of the best in the game.

For starters, the built-in brush bristles are supremely fluffy and soft, and make it a dream to apply. No scratchiness here! The construction of the tube is precise and easy to master. I just pop the top, push down the transparent cover, and sweep the formula anywhere I want to. It also features a twist base that locks and opens the container to emit powder. I once even forgot to lock the base, and the powder didn’t accidentally seep out of the bristles. Plus, it’s the only refillable option on this list, saving you a few bucks each replacement cycle (mine lasts about a month) and minimizes plastic waste.

Additionally, it contains zinc oxide for instant broad-spectrum coverage, along with hydrating ingredients such as hyaluronic acid, niacinamide, bisabolol, and jojoba seed oil. There’s even vitamin C to help fade any discoloration along your hairline and part. The best part, though, is that it’s water-resistant for up to 80 minutes, which isn’t particularly common among most powder sunscreens on this list. However, I appreciate it because perspiration won’t interfere with my UV protection or hairstyle.

It also earned major snaps from dermatologist Hadley King, MD, who swears by this powder sunscreen to protect her scalp. Dr. King calls it an amazing formulation that hits all the key points she looks for in a scalp sunscreen, including mineral active ingredients, non-nano formulation, no white cast, a hydrating formula, and zero greasiness. It’s so oil-absorbing that when she massages it into her scalp, it doubles as her dry shampoo, saving her from having to purchase and travel with an extra product.
