Choose scarves wide and long enough to cover your whole head—in thin, gauzy cotton or silk that won’t be too hot or weigh down your hair. When it’s cold and rainy, a print silk scarf (think Hermès print) worn with a trench coat with the collar popped up looks très chic. Avoid the babushka triangle, tied under your chin, which usually makes women look sad and downtrodden—and doesn’t cover your hair completely.

Under a scarf, your hair is always going to get smashed down a bit, but you can shake and fluff your hair out once you release your scarf.

If your hair is frizz-prone, it will stay smoother longer if you keep it well-hydrated, by washing your hair with conditioner—instead of shampoo—and deep conditioning your hair weekly. Products with argan oil and silicone also coat your hair strands and protect you from the humidity. Not to mention that old-fashioned, trusty hair spray—your head scarf in a can—that goes a long way to hold your coiffure.
