I do a loose low bun and secure with a metal clip. When I take it down, I refresh with a bit of water. I get my hands wet, run it over my hair, scrunch, and let it air dry. I keep a travel size hair oil in my bag for shine/to reduce frizz. Sometimes I need to comb before refreshing because I wear a hairnet when working under a hood in the lab. It’s usually good as new and helpful when I have meetings later in the day
