I've got a very similar Nike one in white, which I've been using a lot recently. Helps keep sweat out of the eyes, shields the blinding sun, and definitely feels cooler. Soak in cold water before the run for added chill factor.
I also got some proper tennis-style sweat bands for my sweaty hands for indoor rowing, and wear those (or one right wrist/Garmin left wrist) which I started wearing on lock-down runs to help avoid touching my face, but wear them out of habit now anyway.

in white
Decrackalon used to do them in white, maybe they're just out of stock at the mo. There is a light grey one:-

(Reminds me, I was going to get a couple of the kids ones for MiniGB.)
Even after a 5k this morning mine was absolutely soaked through (I'd also lost 0.5kg through sweat in just 30 minutes).

Helps keep the sweat off for the forehead as it mostly soaks into the cap and then drips off the peak.
Mostly.
