Reviews

Poor diffuser attachment

"Very disappointed in this diffuser attachment. It keeps falling off my bio ionic dryer and on my clients heads. Preference is one that attaches instead of sliding on"

Michelle W. (1/5)

Inconvenient

"Bought the universal diffuser when I bought the 10x dryer. It’s not a bad diffuser, but it doesn’t really “attach” to the dryer and has fallen off multiple times during use, causing prongs to break off. The diffuser is also so big it literally doesn’t fit in either of my hardshell suitcases. Luckily I kept my old dryer and have had to take it when traveling twice."

Lauren (3/5)

extremely hard to communicate with bio ionic

"I have not received the diffuser even though the text I got said it was delivered on March 12th It"

Doesn’t fit

"Doesn’t fit, waste of money"

Nyssa W. (1/5)

DO NOT BUT

"Doesn’t fit Graphene MX. Plus charged me a return fee when they misadvertised their product that is defective."

Paige (1/5)

Diffuser

"Unfortunately this did not fit my bio ionic dryer and when I called customer service it was truly awful"

Louie M. (1/5)

Did not fit my Bio Ionic Graphene mx dryer

"As diffusers go, it looks like it would do a good job. But it did not fit my Bio Ionic dryer so it was returned. Disappointed that they don't clarify it on their website so I paid for shipping both ways. Not impressed."

Laurie J. (2/5)

Awesome diffuser

"An amazing diffuser. I love that you can adjust the airflow. I’ve used diffusers my whole life and this is the best one ever."

Lori S. (5/5)

perfect fit, perfect design

"This legit fit my Bio Ionic blowdryer and it stays on well. Great design with air flow through the "fingers" as well as through the broad base. I hate the feeling (and look) of wet or damp hair sitting heavily on my scalp. This diffuser gets right to the root to lift and dry my waves."

Sally S. (5/5)

Diffuser

"Works so well. Probably the best one so far with the adjustable air flow. I'm a hair stylist and I am so happy with the diffuser. Definitely will recommend."
