If you're like me and have used a diffuser as often as you have your dentist's flossing recommendation, Warren offered some sage advice: "When you're drying your hair, make sure to use your fingers to pull your roots upward away from your head when the heat is on it, but don't comb all the way through. That'll break your curl pattern."
One diffuser I've since dusted the cobwebs off of: the T3 SoftCurl Diffuser For Cura Dryers (£26).
