16. Pack Your Beauty Products
If you're traveling outside the country, bring your high-end facial products along, says Brown, because most are much more expensive abroad. Safe buys overseas usually include body lotions, shower gels and soaps, talcum powders, and fragrances.
17. Tame Your Tresses
To keep hair looking good without igniting a firestorm of static electricity, Brown keeps a natural boar bristle brush in her carry-on. And, she says, never underestimate the power of a great beret or cloche hat to hide the sins of plane hair. "I also find that a big European scarf wrapped around my neck makes the whole disheveled hair look more chic. Sometimes you just have to go with it!"
18. Get the Grease Out
To help cope with greasy hair that often took an hour or more to wash and dry, beauty expert Jayne Polan invented Shampowder, a dry shampoo that cleans and deodorizes hair and adds volume. It comes in shades to match or blend with your own hair color, and it's packaged in a small, travel-friendly plastic container with an attached hairbrush.
