In order to begin a good blow dry of hair, start with clipping the hair so that small sections can be worked. Use a nozzle that focuses the heat on your hair dryer. One brush that can be used is a nine-row. It is a smaller brush used for small areas of hair. A paddle brush is used for longer areas of the hair. Use the brush to sweep the hair up from underneath. Aim the blow dryer on the hair pointing away from the face. Brush downward and follow the brush with the hair dryer. One section may need to be done several times to get the hair dry and straight.
