If you are looking for volume for your fine hair then I would recommend the Vidal Sassoon VSHA6471UK which is a superb hot air styler. Designed especially to give lift and volume from the root it will give you enviable curls and waves. It is supplied with two brush sizes 19mm and 25mm so it’s ideal for shorter styles too (use the smaller brush) and gives a pleasing smooth finish that is tangle free. You cannot fault the price either, on Amazon.co.uk this retails below the price of a salon blow-out.
I read lots of different reviews about these straighteners and a lot said these aren't genuine. They are definitely ghds just professional ones which means they are lighter. They are exactly the same ones at my hair dressers. I'm happy.
