If you travel a lot (and have wavy or frizzy hair like I do) and don't want to fuss with worrying about high wattage hair dryers or lugging a flat iron, a Brazilian Blowout will give you 10-14 weeks of sleek shiny hair that drys without frizz. Salons in the DFW area are doing them for $200-$300 - so not inexpensive, but for the hassle it saves me hauling heat tools or trying to look fresh in hot humid climates, its worth every penny.
