Davines Quick Fix Circle Mask (£8.50) is one of hairstylist Lewis Pallett's favourites. "The masks you'll always find in my kit are the The Circle Chronicles from Davines, which is a range of seven different masks the come in small, travel-sized pouches (perfect for travelling)," he says. "I love them all, but if I have to pick one favourite it would be the Quick Fix Circle, because it not only provides hair with a surge of hydrating ingredients that make it instantly softer and smoother, but also because for me, time is always the one thing I don't have."
