Winter-Proof Your Hair

Keep Your Cool

When it's freezing out, nothing sounds more comforting than a steaming shower. The problem is, "hot water damages your hair by washing away the oils that hold the cuticle together, which can cause frizz and breakage," says Mary Lupo, MD, a dermatologist in New Orleans. For the sleekest style, take a tepid shower and do a final rinse with cool water to help smooth your hair.
