Dermatologist Dr Anna Chacon also explained how the build-up forms.
“When we brush our hair, it’s typical for hair to shed, and it can get tangled in the brush,” she said.
The truth about the grey fuzz in your hairbrush
“That, mixed with dead skin cells, which are also naturally shedded, create some buildup, and if you have applied haircare products to your hair, those products can also transfer to the brush”
“Top that with dust or other environmental factors, and you get the fuzz.”
And there is another reason you may want to think twice before ignoring it.
Dirty hairbrushes can hold bacteria and yeast, which can then be transferred back onto your scalp. According to the experts, this can contribute to irritation, breakouts, tangling, and even hair breakage.
Also, the grey fuzz can appear surprisingly quickly. With daily use, it can build up in just a week to 10 days, especially if you regularly use styling products.
