Hairizone Universal Hair Diffuser Adaptable for Blow Dryers with D-1.7-Inch to 2.6-Inch for Curly or Wavy Hair, Lavender

This I highly recommend because it fits any blow dryer and it’s the perfect size.

Works with the tiny BaByliss Pro Nano travel titanium hairdryer. Great travel dryer, but it doesn’t come with the diffuser. This one attaches perfectly and stays on! Love it! It’s kinda huge, especially when you hook it up to the tiny travel dryer, but it’s sturdy and works perfectly.

It works fine, but I feel like the mechanism that holds it on the actual dryer needs improvement.

It really works! Stays on. Dries fast.

Great diffuser, travels great and works on tons of hotel and home hair dryers

It worked fine but picked it up one day to attach to my dryer and it literally broke in my hand. Didnt drop it, didnt manhandle it just used it maybe a dozen times and it broke. For the price I wasnt expecting much but this didnt even meet my lowered expectations.

Fits on our cheap hair dryer really well; just make sure you don't have a short-nosed dryer or it won't have anything to attach to. The little teeth design thing is kinda cool, and the grippers for it work surprisingly well. I wasn't exactly whipping it around, but I definitely wasn't gentle with it, and it didn't budge or move around at all.I have super thick, armpit length type 3A curls, and similar products have given me a lot of frizz. This one diffused just as well as the salon lady's though! Helps keep the cast and speeds up dry time by hours.I would definitely recommend for curly hair (just make sure it fits your hair dryer first!)

This has improved my curl days so much
