Review (2/5): Seems defective
Mine seems defective - but i tried the same diffuser at my hairdresser’s and theirs was nice so I added a star. Every time I try using it, it collapses as soon as my fine hair is put in it. I end up spending as much time straightening/fixing the diffuser as I do drying my hair. However, my hairdresser’s diffuser worked great! It even stayed in position when I set it down on the calendar.
