Unlike a true trim, which maintains the lines of your haircut (and may cost you an inch or more if your ends are riddled with splits and breakage), a dusting is a very conservative snipping of just your ends—usually a quarter-inch or less and only in the spots you really need it. “A dusting gives your stylist the chance to snip off split ends before they start traveling up the hair shaft, a practice that can save your hair’s health and, in the long run, its length,” says Faith Huffnagle, Prose’s director of education and veteran stylist. A dusting can often be tacked onto a salon blowout or color service, and many stylists will charge you a nominal fee (or nothing) for it.
By comparison, a true haircut or trim is something you need only do every three to six months, says Huffnagle, and its primary purpose is to reshape a grown-out cut. Regular dusting doesn’t mean you can skip your regular cuts (hair doesn’t grow evenly and even the best cut will eventually need reshaping—especially with shorter styles), but it may enable you to push off that trim an extra month—and, ultimately, because your ends will be healthier, lose less precious length.
