Scalp care?

Hi bald team! What're y'all guys and gals using for scalp care? I shave in the shower with a razor every few days, and moisturise my face (CeraVe), which I rub up to around my mid-scalp. For sun protection I'm always wearing a hat if I'm outside for longer than a few minutes.

I keep getting ads for Bld Bro, but damn it's expensive. Any tips or advice to help maintain a healthy looking scalp? I'd like to keep it moisturised and free from flaky skin and prevent sun damage. Any advice would be great!
