If you're someone who regularly blow-dries and curls their hair at home, it might be worth checking out the L'Oréal Professionnel Blow-Dry Fluidifier (£16), launching on Lookfantastic this month. The blow-dry cream, which is meant to be applied to damp hair before you break out your blow dryer, protects strands from temperatures up to 230°C. But it doesn't stop there. Thanks to some high-tech ingredients that get activated through heat, the cream actually helps your hair hold its shape when you decide to restyle it with a curling iron, a flat iron, or hot rollers.
