Habit 4: Let hair dry naturally Shiny, healthy and strong hair doesn't like heat styling, and the majority of women we talked to said they mostly let their hair dry naturally. Again, these women may just be blessed with a naturally amazing hair texture and therefore don't need to tame it with a blow dryer or flat iron, or they might actually have great hair because they don't subject it to damaging heat. It's hard to judge, but most, like reader Leslie, claim to let their hair "air-dry overnight in a bun" as they sleep. Others say they limit blow dry time to once a week and mostly use the coolest setting on their hair dryer like reader Chrissy who says she only touches a hairdryer when it is "set to cool ONLY". Some, like reader Leylie, also dry their hair "a bit with a diffuser," so they don't have to walk out the door with "sopping wet hair."
