Product Description FITS MOST STANDARD DRYERS: Suitable for blow dryers with nozzle diameter 1.5in to 2in. Our diffuser is not universal and does not fit every dryer. Please measure your dryer before purchasing. FOR GORGEOUS CURLS: The oval shape of our collapsible diffuser hair dryer attachment helps give a better curl formation in less time. UNIVERSAL DIFFUSER ATTACHMENT: The diffuser fits most standard hair dryers. The larger size of the diffuser allows the air to have more time to cool before hitting the hair, meaning less heat damage to your luscious locks. FITS MORE HAIR AT ONCE: The larger oval shape fits more hair than the standard hair diffuser for curly hair, saving you time and allowing you to dry more hair at one time. EASY TO TRAVEL WITH: The portable diffuser collapses to take up little space in your purse or suitcase and comes with a travel bag to help keep it safe from travel damage. DESIGNED BY HAIR PROFESSIONALS: We’ve designed a salon-quality diffuser that we use daily in our salons, so you can trust the best curly hair results while using it at home.
