Triumph Over Humidity

Wash your hair less—every two to three days at most.

Use shampoo designed for unruly hair.

Rinse out only half your conditioner—what's left leaves shine and weight.

Smoothing creams and serums make an enormous difference when worked into wet hair before styling.

Layers avoid puffiness at the ends.

Lock out frizz with leave-in conditioner and/or smoothing cream.

Air-drying is essential: The blow dryer encourages too much fullness, not to mention flyaways.

Get a blunt, angled cut. Over-layering removes too much volume from limp hair.

Color your hair; dye ruffles the cuticles slightly to create fullness.

Try clear gloss treatments; they bulk up roots

Thickeners do help—work throughout your hair.

A light—and this is important—anti-humectant hairspray keeps moisture in the air from weighing your hair down.
