When should I replace my brush?Updated a year ago

On average, brushes should be replaced every 6 months to a year, but this depends highly on the amount of usage and the hair type the brush is being used to style. Individuals with thicker hair may “wear” out the brush bristles faster than an individual with thin hair. Also, the type of brush used and with what accessories the brush is being used with can greatly affect the brush's longevity, for instance using a round brush with a hair dryer. Round brushes usually have the shortest longevity due to their use with hair dryers and the heat that degrades the brush’s bristles over time. These round brushes can sometimes be replaced every year.
