We know when to throw out old makeup products and even when to replace our eyelash curler, but when it comes to letting go of our hairbrushes, things tend to get a bit more complicated. The best way to determine if you’re in the market for a new Mason Pearson is to examine those bristles. If they’re starting to fall out or have a worn-out appearance, it’s definitely time to toss, says Judy McGuinness, a senior stylist at Mizu in New York City.

“To get the best out of your brushes, make sure you are cleaning them regularly,” she tells InStyle. By this the pro means removing the hair out of your brushes after every use and soaking them with shampoo and warm water at least once a month to get rid of grime and product buildup.

When giving yourself a blowout, McGuinness says you should also avoid placing your hair dryer directly on your brush, as this will melt the bristles and damage your strands. Another incentive for some extra upkeep? “With good care, brushes should last a few years at least!”
