A Genius Invention: Toni & Guy Universal Diffuser

I remember when hair diffusers were all the range, being used to create curls and waves in the late 90’s before hair straighteners really took off. I hadn’t used a diffuser for years, believing my perm-look curls were well and truly behind me, until this landed on my doorstep and totally revolutionised my opinion of the gadget. Diffusers can not only be used to create curls, waves and volume, but can also help to reduce frizz and protect hair from heat damage. When added to the end of a hairdryer nozzle, a diffuser helps hot air to circulate and dry the hair gradually by dispensing it over a wider surface area; using a nozzle may help to get super sleek locks, but it’s also damaging the surface of hair by targeting a small area with incredible heat. Diffusers can help alleviate that problem and minimize frizz, as well as creating gentle volume at the root. Until now they’ve been ugly and chunky bits of kit that were shoved at the back of a wardrobe; however, Toni & Guy have launched a universal diffuser that not only fits every hairdryer, but collapses down to ensure it’s travel appropriate and a great space saver.

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.

    This genuinely is a 'genius' product! I had my hair permed in November and replacing my hairdryer was a right pain in the bum. Not to mention that finding a diffusing hairdryer was a nightmare! Stephaniehttp://missstephanieusher.blogspot.co.uk/ http://www.bloglovin.com/blog/3436251 xxxx

    Forgive me for not knowing what a diffuser is, but I'm still not quite sure what it actually does?ellabooxo • beauty & lifestyle

      You add it to the nozzle of your hairdryer!

    I would love to try this and see if it could help my nightmare curls and give my straighteners a rest. x

    Inspite of what the blurb says it is not a universal diffuser. I have been using a Remington travel Plus hair dryer (light weight) for years and the nozzle is ovalEventually got the diffuser on and watched it slowly slide off

      That's why I said you'll have trouble with travel dryers – they're not made to the same dimensions and it was never intended for travel dryers.

    I can NOT get this Tony & Guy diffuser onto my Tony & Guy hairdryer. I am exhausted after fighting with it for a hour and my hands are sore.
