Sun help

My daughter has the thinnest hair still (plus it’s barely grown since she was 6m). The top of her head you can easily see her scalp. She used to be good about wearing hats… not anymore. She’ll tolerate it for a few minutes then rip it off and refuse to wear it. Do I literally just spray sunscreen on her head then?! Her scalp gets pink fast so I know she’ll burn if I don’t either get her wear a hat or rub sunscreen (or spray) in her hair. Which is beyond disgusting. Anyone have any suggestions?

Update:

So I did sunscreen her head this PM and omg it made her scalp even more insanely visible since her hair clumped together and worse like she was almost bald 🤦🏻‍♀️ I hate his!
