Not sure what you ladies do for hair-care when living out of a suitcase.
On days when washing is not an option, (1) dry-shampoo roots, followed by (2) oil ends, is pretty much my only defense against what life on the road tends to do to hair. Ponytail if all else fails. (Or in this case, simply adopt the headgear of a certain military man pointing his crafty camera at me.)
