The way you style or comb your hair can greatly affect how healthy it is. The American Academy of Dermatology offers a few do's and don'ts for taking care of your hair, including handling your wet hair as little as possible.
Let your hair air dry at least partially before combing or styling, the dermatologists advise. There are some exceptions to this rule though:
Most people should handle wet hair as little as possible as wet hair breaks more easily when combed or brushed. However, people with tightly curled or textured hair should brush their hair when wet to decrease the chances of hair breakage.
The video above points out additional tips, such as avoiding "long-lasting hold" styling products (or at least avoid combing or brushing after you've applied them) to prevent hair breakage or hair loss. Keep your locks strong and healthy!
