Left to my own devices, my hair can look more Worzel Gummidge than Gigi Hadid, however this spinning gizmo has genuinely changed that. First things first, the name is a misnomer; this will not give you huge, voluminous hair. If you're after actual big hair, look somewhere else. What this does do, is create a smooth, professional looking blow dry. It's the at home version of a round brush and hair drier for the cack-handed. I have thick, wavy hair that is almost bra strap length. The big hair has a round brush which blows warm air out and has an optional spin. What I particularly like is that you can change the direction of the spin which makes it easier to do both sides. I rough dry my hair and then "big hair" it in sections. Starting at the roots with the big hair underneath my hair, I turn the spin on and pull the big hair down my hair. The brush wraps the hair around it and smooths my hair into a sleek shape. I love that it leaves my hair without any frizz and in a great shape that compliments my waves. It doesn't leave it flat or poker straight like straighteners. I also like that it doesn't get too hot and that it's fairly forgiving of your technique. OK, so my "big haired" hair won't rival Gigi's on the red carpet but it has given me better blow dries than I've had at numerous hairdressers and I no longer feel the need to visit a hairdressers before special events. The ultimate question: will I replace it when it eventually dies? Yes. Immediately. In fact, I've been tempted to buy a spare in case Babyliss ever change the design.
