These types of hats flatten your hair the most, so there’s no point in trying to maintain the volume — just being honest here. A low-maintenance French braid or side braid works best, says Grmolyes. Keeping it nice and tight, braid your hair down the back of your head, or pull it to the side and bring it over your shoulder. That way, even if you decide to take your hat off, your hair will stay in place.
