When it's time to lather those locks

WHO knew hair-washing could be so . . . complicated?

A lot of women, warned by beauty editors and websites that shampooing too often was the culprit for their parched strands and out-of-whack scalps, have cut back on their shampoo regimen.

Instead of regularly lathering up at home, a weekly routine might now go like this: a blowout at a blow-dry bar, dry shampoo, dry shampoo, dry shampoo, followed by another professional styling session, and so on.
