Hair

I’ve been doing hot mat Pilates for a while now, and my hair has really taken a toll. I love working out in a hot room, but being in a 95-degree room with a bunch of other sweaty people 3–5 times a week has caused my hair to become dry and frizzy all the time. I only feel comfortable wearing it in a bun now. What do you other hot Pilates-goers do to prevent/manage this? TIA!
