01 BEFORE LEAVING THE HOUSE…
Comb through a light, leave-in hair serum (Kérastase Nutritive 8H Magic Night Serum, £36) and let it dry as you head to the airport. Moisture evaporates much faster on a plane than on land, decimating the water reserves in your skin and hair.
02 ONCE YOU’VE CLEARED LUGGAGE CHECK…
HEAD STRAIGHT TO BOOTS for a bottle of Vicks First Defence Nasal Spray, £6.55. A recent study showed that any person full of cold seated within a meter of you on the plane is 80% likely to infect you. Spritz this up your nose to kill the bugs (which breed in your nasal passages) dead.
03 AFTER SECURITY
Plane-cabin air pressure can expand intestinal gas by up to 30%, so choose your food wisely in Departures. Load up on lean protein – like Pret’s crayfish and avocado salad – and skip anything salty. The extra sodium will only exacerbate water retention.
