Very weird yoga teacher question but curious!

So I teach hot yoga about nine times per week, sometimes 10-11 classes. But have fine, kinda oily prone hair no wear it up off my face on a tight ponytail but it’s literally sweaty each class. I’m 58 yrs old and get my roots colored every month for the grays. The hair has been a challenge for me, and laundry. Anyway, I’m wondering if it’s better to just wet and blow dry my hair every three days and live with some oil or shampoo and let air dry (which makes me look and feel kinda yucky) daily! What do you do for those that teach hot and sweat daily for your hair? I haven’t found the right protocol these past two years and I’m kinda at a loss. I either look good for a day or two and crappy the rest of the week or I’m drying out my hair much?? Advice welcome please !
