Hate those telltale roots that start to reappear around week three, but the salon prices even more? Root Rehab to the rescue! Master colorist Kelly Van Gogh has launched a home emergency retouch kit to extend your color between salon visits, completely covering gray. It magically “reads” the color of your hair and self-adjusts to your color; there are nine shades that Van Gogh promises will match 90 percent of all hair colors. An angled nozzle allows for precision coverage so you don’t ruin highlights, and the formula is so rich and creamy that it stays on your hair (and slides off your skin for no staining ever). And to be eco-friendly, you can reuse the applicator bottle, hairline brush, and gloves. $39 at Space NK, 24 Harwood Ct, Scarsdale (914) 472-1214
You’ll never have a bad hair dye again.
