What do you say to someone who parts his head and his facial hair to apply sunscreen?

Nothing and I would move on.

Is that if it’s a stranger or someone you’re friends with, or both?

I would say “Bravo”! You are a smart man to apply sunscreen to avoid skin cancer.
I had two places on my head that had to be removed.

I would say “feel like getting a beer?” and ask him if he knows any crazy women.

Good idea!

I’d turn my back to him, and say nothing.

For anybody who is sun sensitive and doesn’t wear a hat, it’s essential. I do it. I have very light skin and sun damage on my head and forehead. Normally I wear a hat, but sometimes I can’t or don’t and I put sunscreen where my skin is showing.

But this is about parting the hair because the hair is thick enough to not expose skin.

He is trying to prevent skin cancer. Why do you care?

@flo The hair is often not thick enough to prevent sunburn. Just because you have hair does not mean UV radiation can’t get to the face.
