Using a hair sheet mask isn't the only way to take care of your tresses this winter, although it is a simple way to boost moisture. Besides adding a mask to your weekly routine, Schulte recommends shampooing every third day (depending on your hair's texture), making sure your regular conditioner is a moisturizing one, and using a leave-in conditioner (try Unite 7Seconds Detangler, $10) and heat protectant prior to blow-drying. She also suggests applying an oil serum to dry hair after styling if you experience frizz and static.
