Does your hair keep your head warm in cold weather? Do you only need to wear a head band/ear muffs, or nothing at all on your head? Until this year, I would never have gone around in fall weather without a hood and/or hat on. But this year, I'm realizing that my hair has gotten so thick, that I don't feel cold air on my scalp anymore! My ears still get cold though. I always wear my hair up . Please share your experiences!
