"By now you may have realised I love all things Rahua, and the Rahua Hydration Detangler + UV Barrier ($32) didn't let me down. It's infused with three types of hydrating, frizz-fighting oils, yet it's lightweight enough for my fine-ish hair. I usually cocktail three or four different products before I blow dry, but this easy-to-use mist replaces them all." — Dawn Davis, senior editorial director
