On a short trip with no checked baggage, there's no time to waste on the TSA. If you're traveling light with just a carry-on, avoid the 3-1-1 liquid policy (3.4 ounce bottles or less, one-gallon plastic bag, one bag per passenger) altogether and fly dry. Stock up on TSA-friendly alternatives to liquid products, like Lush's Toothy Tabs (lushusa.com, from $4), foaming toothpaste stand-ins that come in a variety of flavors, and J.R. Liggett's bar shampoos (jrliggett.com, $7), which are detergent-free and come with a range of supplements for hair health. Finally, remember to pack a reliable solid deodorant—gels and aerosols are subject to the TSA's 3.4-ounce rule, but the stick stuff isn't.
