You always get 2 nozzles with every dryer. The first one is big and narrow, while the other one is small and a little wider. So, if you are working on coarse, thick hair (wavy to curly type) ideally you should use the first one for a more concentrated air flow & a nice finish. If the hair is fine, brittle or chemically treated, it is advisable to use the second nozzle to maintain the quality of the hair.
