body{margin-left:12%}Product ReviewsRated 4.55 out of 5 stars40 ReviewsMost Helpful Positive ReviewLove it! Exactly what I needed!This diffuser fits perfectly on my BIO IONIC dryer, has extended fingers that works great for my long hair and feels great on my scalp. The diffuser also has customizable vents to better control the airflow for my hair needs and helps me minimize hot spots in my hair. It's well built and I love it! I read some reviews that stated the diffuser didn't fit their blow dryers that were of a different brand. The diffuser box stated it was a Universal Diffuser for BIO IONIC dryers and it had photos of all of their different BIO IONIC dryer models. I hope this helps minimize the confusion. Luckily, I have a BIO IONIC 10X Ultralight Speed Dryer and it's been my absolute favorite dryer and this diffuser was the perfect accessory for pretty, defined, frizz-free curls in literally just a few minutes with minimal heat! Highly recommend!Most Helpful Critical ReviewDoes not fit Bio Ionic GrapheneMX™ Professional DryerFalsely advertised as universal to Bio Ionic brand. Does not fit Bio Ionic GrapheneMX™ Professional DryerReviewed by 40 customersPerfect fit and function5J'me from Bel Air, MDFit my Amika hairdryer perfectly and works well in allowing my slightly wavy fine hair to do it's natural thing. I have wavy underneath hair and straighter top hair and with this, I cup it in sections and it's the same all over. Just what I wanted.Terrific Diffuser5Eileen from PAI searched all over looking for a diffuser. This one works very well. It fits nicely over the end of my dryer which is about 2", due to its stretchy cuff. The longer prongs really do help define my curls. Excellent purchase.Diffusing Excellence for Responsive Curls - My Hair Loves It5Robin C. from UndisclosedOne of the best hair gadgets ever discovered and purchased! It works perfectly. It's easy to use, and my natural curls respond with more curliness.Diffuser5Cynthia W. from UndisclosedI had been using the "claw" type diffuser and decided to try this one. It has made such a difference especially on the top which had been somewhat flat. This helps me create beautiful curls. I have had many compliments on my hair since switching to this diffuser. Highly recommend.Well done5Susanna W. from UndisclosedWell doneI love this diffuser!!5Cindy S. from UndisclosedI love this diffuser!!Very happy!5Jenessa H. from UndisclosedWorks great. Dries my hair fast. I bought the bioionic based on a previous review that said it worked well on her fine hair. I'm glad I did - because it does. My hair is very smooth after, I haven't needed to straight iron.Best of the best!5Jonni D. from UndisclosedBioionic is the best of the best when it comes to hair styling.

That said, I like that it fits correctly on my bioionic and doesn't scratch the barrel like a generic might.Works well5Mary W. from undisclosedHonestly, I feel like all diffusers are pretty much the same.
