The Hair Straightening Brush is essentially a round or flat brush that has a blow dryer inside of it. You can use it on your hair the same way a stylist would use a brush and blow dryer combination on yours. While you can't use it on hair that is soaking wet, you can use it on hair that hasn't finished drying. If you use a brush like this to dry your hair, it will have a straight and finished look. You'll be really impressed with the appearance of your hair.
