I've had this same question in the back of my mind. Most of my products have glycerin in them up high in the list, and reading about how dry hair can have an opposing effect is kind of scaring me. I've always worn my hair naked and it's always super dry in the winter time. Now I wear a leave in and gel. Would this be appropriate for low dew points as well, or should I find products without humectants? If you seal, will that be sufficient enough?
