This Review Title is First diffuser in my whole life... and the content is: I have never bought and used a diffuser in my life. I have had hair stylists use them on my hair. This thing was great! It fit on my Conair hairdyer (which has a 2 inch nozzle). My hair is very thick so it takes FOREVER to dry it, but not with this thing! Also I have never been able to style my hair curly without alot of fuzz, until i used this diffuser! The one downside (wasnt that big of a deal to me) is that it dose collapse while using it but it still works! I have only used it once so far so i will write additional reviews if something changes. Oh and it dosent come off of the dryer easily which is good (there are silicon prongs on the inside so it fits the hairdyer). I read alot of reviews before purchasing this one (it was between 3 different diffusers). Hope this helps anyone that is considering buying one..There are other information for this review, one is This reviewer did purchase it and the other is 22 people think this review is helpful.
