For quick trips -- or infrequent hair-washing travelers -- nothing beats shampoo and conditioner in pre-measured packets. Instead of swiping samples from your salon, pick up the Oribe Beautiful Color Travel Set, $19.50. It comes with seven dual packets of Oribe's amazing shampoo and conditioner, as well as a mask for when your hair could use an extra boost.

If you're really into your nails, traveling without nail polish remover probably gives you the same feeling as forgetting your phone charger: utter helplessness. Butter London Scrubbers, $10, are tiny, weigh nothing and work incredibly well. Put one in every makeup bag and toiletry case, and you'll always feel prepared.

Calming, hydrating beauty products can do so much to improve a miserable flight. They can (almost) make you forget all about that screaming baby or the neighbor who's snoring in your ear. Tata Harper Skin Care Daily Essentials, $70, is the ideal "keep it in your carry-on at all times" kit. It comes with a hydrating mist, cleanser, moisturizer, mask and a nourishing serum that's so light you can even tap it on over makeup.

French travel-inspired fragrance line Memo Paris just launched stateside, and it's exclusive to Bergdorf Goodman at the moment. While the collection of scents -- each one more complex and beautiful than the last -- is rolling out gradually, I'm most excited for the debut of the Leather Fragrance Carrier (hopefully this summer). It's an exquisitely crafted leather case that houses a miniature glass bottle of the Memo French Leather fragrance. If you want it now, you may have to visit Colette in Paris -- but at least you'll have all your other travel beauty essentials ready for your trip.
