In the winter we live in dry environments, home and work. Staticy, dry hair lays flat to the head and will always be flat. Overlaying light moisturizing conditioners like silicone, glycerin, and polyquatemium will plump up the hair, hold curl, and reduce static. These are all light moisturizers that seal in needed moisture and eliminate static. They need to be overlapped gently, heavy conditioners are a no no in the winter.
