8 of the Worst Things You Can Do to Your Hair

It may seem like common sense, but a regular hairbrush and wet strands should never intermingle. "People often don't know that when our hair is wet it is elastic, making it able to stretch and weaken much more easily," says celebrity stylist Justine Marjan. Of course, there are detangling brushes specifically made for wet hair, but your basic boar bristle brush should be reserved for dry styling. "It's important to be gentle with wet strands, as they are much more fragile and can easily break or snag if we are too aggressive," Marjan adds.
