To treat frizzy hair: Minimize heat styling and always use a heat protectant when you do. Avoid blow drying if possible, if not use a low temp setting and low fan speed. Blow air only parallel to the hair strands, not perpendicular. Hydrate the hair with moisturizing shampoos and conditioners, avoid sulfates.

Those with wavy and curly hair can adopt a less frequent washing schedule—depending on your scalp condition, one to two times per week is generally ideal. Waves and curls tend to be drier than straight hair, and over-washing may leave it dry, brittle, or frizzy.
