There’s one thing for certain: this is the Ferrari of hairdryers. The Dyson Supersonic comes with a fairly eye-watering price tag, but for that you get cutting edge technology that is streaks ahead of most competitors. The product is capable of drying hair in half the usual time, leaving it so shiny and smooth that many people who use straighteners will find that they actually need not to. Dyson have combined ultra-powerful, directed airflow with a heat-protection sensor to achieve this, which is also good news for the longevity of your luscious hair. It’s quiet too, so you won’t wake up the family.
