Lightly pre-dry the hair with a towel to remove excess moisture. Apply heat protection if needed. Then select the appropriate attachment: The extra-narrow concentrator nozzle is ideal for straightening or shaping, while the professional diffuser defines natural curls. Select the desired temperature and blower level on the hair dryer. Divide the hair into small sections. Guide the hair dryer evenly from the roots to the tips. Use a round brush for additional volume. At the end, set the styling with the cold/cool air button to achieve long-lasting results.
