We're adding a new brush to our shopping lists as we speak!

What if we told you that that ancient brush you've been using since George W. Bush was president could standing between you and the good hair day of your dreams?

It turns out that beautiful hair starts with a good, clean hairbrush, which, experts say, is where many women go wrong.

John Stevens, research and development lead of Goody Hair Products, told Today that a good rule of thumb is to change your brush every six months. He added that melted, separated bristles and cracked beds are telltale signs that it's time for a new brush. Experts also advise keeping an eye out for broken bristles, which can get caught in your hair and even tear it from your head.

To get your brush to the six-month mark, regular cleaning is vital.

"To extend the longevity of your brush's lifespan, it's best to remove the hair from it after each use and thoroughly clean it once a week," said Stevens. He recommends using the pointed end of a tail comb to remove discarded hairs from between bristles.

"It's also important to clean out your brush to keep your hair healthy and safe. Buildup in a brush isn't just dead hair; it can contain dust, bacteria and hair product" he added. "If you don't clean out your brush, you may run the risk of transferring this buildup back into your hair and scalp."

Speaking with Today, Elisa Fitzpatrick, a senior stylist at SEVEN Salon in Seattle, recommended simply cleaning the brush with mild shampoo and warm water every so often. Laying the brush on its bristles to dry allows the water to drain and not get trapped in the brush, which can cause mold.

"Ultimately, a great, well taken care of brush can be really helpful to hair health," Fitzpatrick concluded.
