How do I protect my hair from a heated room like bikram yoga class or a sauna?

I naturally have very thick, dry, and brittle hair. I am taking up bikram yoga and was wondering if anyone know how I would proctect my hair from all that heat. I've noticed when I sit in a sauna for 20 mins. I've noticed that my hair gets super dry and more damaged.
