The H2D Magicurl Waver Wand is a large 32mm barrel that heats up to 220 degrees, and creates a loose, relaxed wave. I'd recommend for ladies with shoulder length and longer hair, due to the size of the barrel, shorter hair wouldn't really benefit. It's easy to use, and comes with a heat protection glove to avoid sizzled fingertips. I particularly like the swivel cord - something I'm very used to smacking in my face and getting caught up in. The design is simple, I do wish it had an adjustable temperature, as 220 degrees might be a little too high for some fine haired ladies. One thing with the H2D Magicurl Waver Wand is that you can get round your hair quickly, it only takes around 6-8 sections of my hair to finish, so is great for a last minute 'get ready and go'.
I think it's such a good idea to carry a mini 'emergency hair kit' in your bag, not only if you need an extra pin or spritz of hairspray, but to perhaps be a style saviour to another guest! Pop a mini hairspray, and some hairgrips in your bag just in case, and if there is enough room, a compact Tangle Teezer.
