If you’re in hot and humid weather and you have curly hair, straightening it is pretty much useless, so the next best thing is to wear it curly and for this, I love a good serum. It minimizes the frizz and leaves your hair soft and defined. Lots of serums have dimethicone or some other form of silicone in them, but the Bumble and Bumble Hairdresser’s Invisible Oil also has a blend of different oils that help condition your hair. The result is frizz-free defined curls and healthier hair.
