The rubber texture and flexible end ensure this fits over every hairdryer imaginable and stays put (unless it's a travel dryer where you may have a slight problem.) It expands to almost triple its size, providing a salon professional tool that can be used to aid pretty much any style. The spikes help you to grab hair and manoevre it around the unit, while the vents ensure hot hair is dispensed equally over the surface of hair. It's such a simple idea, but until now a decent diffuser seemed about as unlikely as Marty McFly's electronic laces. I know that I'm going to start using this to create volume at the root, as well as to create delicate waves throughout my hair for a casual boho look. For such a genius idea you'd expect it to cost a small fortune, but you can grab one of these for only £14.99 (and from Argos of all places.) What do you think of this universal diffuser?
The Toni & Guy Universal Diffuser is available from Argos priced £14.99.
