Daily brushing and styling can take a toll on your tresses, robbing them of natural oils and leading to breakage. Trade in your plastic brush for one with natural bristles (look for boar), which redistribute oils throughout hair as you brush, boosting shine. “The only time I use anything but a boar-bristle brush is to detangle wet hair,” says Harry Josh, creative consultant for John Frieda Collection. Natural bristles are also less likely to break hairs. Use them consistently for fewer flyaways.
