Want shiny, frizz-free hair? Try a hair cocktail of anti-frizz shine serum and leave-in conditioner. According to Stone, this combo works on all hair types, and will repair your hair as well as tame flyaways. He recommends Kerastase Nurtritive-Serum Oleo Relax, $39, with Paul Mitchell Tea Tree Scalp Moisturizer, $17.81.

The trick to making this hair cocktail work is to start slow, and not use a lot of product at first. (Start with a dime-size amount of each product.) Otherwise, your hair will look greasy, and you’ll need another shampoo to correct it. Stone says you can use one product at a time, or mix the two together. Both products should be applied throughout your hair, then blown dry.
