Think about it, when’s the last time you gave your hair iron a good wipe-down? While you generally use a hair iron on clean hair, the products and serums used for styling can build up on the ceramic/metal plates. This buildup can cause uneven heating and in turn damage your hair.
The best way to clean your iron is wiping it down with a bit of white vinegar. The vinegar will dissolve any oils or dirt accumulated on the plates and leave your hair iron looking good as new!
