My SIL used to condition and moisturize the heck out of her hair in the winter, because she thought it was dry. Well, it wasn't dry, it was full of static! One day I pulled a dryer sheet out of the pocket of my purse, brushed it lightly over my hair (which was flyaway that day) and she was amazed at how my hair calmed down. I think she keeps a dryer sheet in her purse now, lol.
