Mistake: Not drying your hair enough before using a tool such as a round brush.“The bristles on the brush are not designed to run through soaking wet hair, and the concentrated heat of the blow dryer right on wet hair can be damaging,” says Sarah Pozefsky, hair stylist at Complexions Spa for Beauty and Wellness.Instead, power dry hair to remove about 75 percent of the moisture before using the round brush.Source: HealthyLife magazine   Photo: Joe Belanger/iStock, IStock
