Review (5/5): Such defined curls
This diffuser is by far the best I've ever used--and it's the most affordable! Because of the way it is made, I'm sure it would fit on any hair dryer. I've tested it on 4 different ones and it fits perfectly because it grips to the mouth of the dryer. It has given me extremely defined curls with basically no frizz. It's super convenient to travel with, as well, because it is collapsible. I was worried that this would mean it's not sturdy and effective at drying hair, but I was wrong. This is definitely the diffuser to buy.
