The last time I tried to fly I woke up on the floor beside the bed. And the time before that airport security confiscated my juice box. Needless to say my hair was unkempt. So how can you get some shampoo on your next flight without a hassle? Simple -- Paper Shampoo.
Paper Shampoo comes in boxes of 30 sheets and costs $12.50 for two packages. They dissolve into a lather whenever you add water (including salt-water, which is awesome because I do the majority of my bathing at sea). Plus they're mint scented. And if there's one thing I've learned in my 40-odd years on this planet, it's this: mint-flavored hair is freaking delicious.
