Any time I travel, I always dread bringing my blow dryer with its attached diffuser. I purchased this collapsible one, and let me tell you it is my travel essential! It fits in my backpack and suitcase. I always have access to a blowdryer, so I just whip this bad girl out and attach it to one. It diffuses my hair really well, and I say it is a must-have item for your curly-hair routine.
