Curly hair can feel like a curse when the humidity’s high. I’ve tried a number of hair products to control my frizz, but none work as well as Tresemme’s “Flawless Curls” — a lightweight mousse that contains keratin to condition hair and enhances its natural waves. Unlike gels and creams, which can make curls feel stiff, Tresemme’s mousse doesn’t leave any residue. To boot, it’s affordable: only $5 for a ten ounce canister.
