Initially when hair is wet, use dryer on high speed, without the concentrator nozzle, to get the moisture out - dry hair until it is damp. Attach concentrator nozzle, using medium to high speed to style and/or straighten hair. Always blow dry hair starting from the root down to the ends. Use cool shot button to lock in style. For even better results, try using One 'n Only Argan Oil Treatment with your blow dryer to eliminate frizz by smoothing the cuticle for silky, conditioned, and healthy looking hair. One 'n Only Argan Oil Treatment helps protect against damage caused by chemicals, and excess heat from styling and environmental factors.
