Adjustable Diffuser Attachment for Hair Dryer Hair Suitable for 1.4 inch to 2.6 inch, Diffuser Hair Dryer, Universal Hair Diffuser for Curly Hair, for Fine Thick Natural Wave and Frizzy Hair

Very universal. I had to buy a new blow dryer and was worried that it wouldn’t fit. But it does.

I can't believe this fits my little travel hair dryer! It's a BaByliss Pro TT, 1.5" or 37mm end. The photo looks ridiculous because of its size (same as my spread out, medium-sized girl hand), but it is awesome for drying large amounts of curl at the same time and diffuses the heat very well. This attachment is bigger than my entire dryer but stays put. Now, I'm not throwing my arm around to dry my curls, maybe it would go flying across the room then, but not one should be treating your hair or appliance as such anyway, so I won't go there. It's not an ultra-tight hold but has a gripping material at the opening to hold on to the hair dryer and it does very well, plus is easily adjustable (twist to open, release for it to snap onto the dryer). I'm so glad I read reviews and tried this one, it holds up where many others fail because of compatibility with a smaller dryer. Highly recommend!

I've been using this diffuser with my own hair dryer for a few weeks now and it works great. It is larger, and I haven't on my smaller sized hair dryer but it will fit any size, and probably would work best with a full size hair dryer (my hair dryer is more of a compact travel size). The diffuser adjusts to any diameter, which is great. It is very secure too, it's never slid off or been cumbersome. Overall, for the price it is a decent diffuser and a good addition to your hair routine supplies.The only thing that would take off a star is that it is pretty heavy. While this does add to, its durability, if you have a lot of hair that takes a while to dry, your arm will get tired holding the weight of it. Otherwise it's a good product.

This works really well. I bought to replace the diffuser that came with my hair dryer that likes to fall off as soon as the plastic gets warm. It stays on really well with my brand of hair dryer which was also purchased on Amazon. I don't even have to lock the mechanism to get it to stay on, my hair dryer has a bit of a matte finish which may be why.. I also think the larger diffuser surface is drying my hair faster than the old one did. Bonus(!) because thick curly hair takes forever to dry.

Nice, but did not fit my hair dryer.

My 14 year old daughter has been flat ironing her curly hair for a few years now but the heat has done so much damage that she wanted to give her hair a break and start wearing her hair curly again. I could have sworn that her hairdryer came with a diffuser but I couldn't find it so I ordered this adjustable one. When I opened the package, I was shocked at how big it was but it had great air flow and it did the job that a diffuser should do. It would be less awkward to use if the diffuser was smaller but overall, my daughter is happy with the diffuser and is very happy to let her natural curls flow again!

If you're like me and have been using the diffuser that came with your hair dryer forever. Stop. It's time for an upgrade. I had no idea what I was missing. I included pictures as an example of what I thought a diffuser was supposed to look like versus what this baby looks like. It is so nice. The size makes it so much easier and quicker to do your full head. The universal attachment function is really clever and I really think could work with just about any hair dryer. Certainly a huge improvement to my old simple hair dryer and it was attached very securely. Love love love.

As you can tell from the picture, this particular diffuser is pretty massive, BUT it is very light weight. It’s not the best diffuser I have ever had. It still has a lot of air that comes through it even on the low setting. I haven’t even tried high because of the amount of air coming through it on low, my hair would be a frizzy hot mess if I tried. This will work for now but I am searching for something a little better.I am unsure why people complain that it doesn’t fit their hairdryers. The opening, when you twist the top, is pretty large. My hair dryer is an Infiniti pro and there’s ample room around it when I put it in and then you have to push the button to let it close on the dryer. Perhaps maybe they weren’t twisting it open and then pushing the button 🤷‍♀️
