I dashed to Aldi this morning to buy the Remington Volume &Curl air styler. I thought for £19.99 it was worth a try.
I've just used it and I'm seriously impressed. My hair is now jaw length, layered bob, and thick. It's really easy to use, there are 3 different sized brush attachments, plus a nozzle, so an attachment to fit every length of hair. I used the medium size. It's quick and manageable to handle, with a cold blast button and 3 heat settings. It doesn't rotate so your hair can't get tangled in it.
It gets good reviews on Amazon, and I can see why. Big from me.
