A product originally made for car care, Son of a Gun, is all the buzz on the doll forums right now. According to those who have used the product, the vinyl protectant leaves American Girl doll hair like new. From a spritz on some dry bangs to a soak for Addy, it is getting nothing but rave reviews. Luckily none of my dolls are in need of the treatment yet, but we will keep it in mind for future hair emergencies.
