HAY GUYS, what do you do (if anything) to protect your scalp from the sun?

I'm been all slathering myself in sunscreen, only to get scalp burn... I would kind of like to avoid skin cancer of the scalp! But hats! They always look so dorky on me! (Putting aside the fact that hats meant for poolside/beachside wear are often pretty dorky even before the addition of yours truly.) Does anyone have any solutions they think are non-dorky???

Also, does anyone else have a problem with their body darkening much faster than their face? MY ARMS AND CHEST, OMG. Over the past few years, they've been darkening so much more dramatically than my face! Which doesn't even make sense, given that my face gets more direct exposure more often! I've been leaving my face un-sunscreened for 30mins or so, lightening my arms and chest with vinegar, exfoliating like mad, BUT IT'S ALREADY HAPPENING! And I've only been out 3 times so far this season! Idk what it is, maybe my face is just really healthy from all the olive oil cleansing, and thus is more sun-resistant? BUT I WOULD LIKE NOT TO BE FREAKISHLY MISMATCHED.

If anyone has any advice, I'd appreciate it. DX
