Wash hair with cool water rather than hot to control frizz. As heat is one of the major causes of frizzy hair, use straighteners and curling irons as little as possible.
Use salon-quality shampoos and conditioners to help treat frizzy hair. These brands do not contain alcohol and other harsh chemicals that dry out hair. Products with a protein, such as keratin, make hair healthier and also help prevent frizz.
Mid-afternoon frizz can be prevented by lightly applying anti-frizz products during the day. Drying only the roots adds lift to the hair without over-drying the follicles and tips.
Everyday Health recommends wearing hair in a bun if frizz is unavoidable.
