We know. This is news to us too.

If the thought of replacing your hairbrush every so often isn't something that has occurred to you, we're here to say you're not alone. Apparently, as we recently found out, it's not okay to hold on to the same trusty bristles for years on end. While an exact time frame varies slightly, even with proper care, a hairbrush should be replaced much sooner than you might think, and here's why.

Every time you run a brush through your hair, the bristles are collecting dead skin cells, product, and oil (among other more alarming things). With each pass-through of the brush they're getting added back into your hair, which can both weigh it down, snag strands, and perpetuate common scalp issues like dandruff and eczema. Not to mention, all of these unsavory brush cling-ons can create a breeding ground for yeast and bacteria. Removing hair after each use and giving it a deeper clean once a week will go far in reducing cross contamination, but it doesn't eliminate the need for replacing your brush every six to 12 months.

We understand this might not be welcome news if you've recently invested in a pricey boar bristle brush, justifying the purchase with a belief that you'll have it for years. Even expertly crafted tools will eventually lose their luster and, while they may have a better shot at hitting the 12-month mark, they too will need to be replaced eventually. Determining when you need to start hunting for a replacement is as simple as taking a gander at the bristles. If they're missing, melted, or fraying it's time to say goodbye.
