The Fastest Way to Conceal Grays
Cover them with mascara. As women age, hair follicles lose the ability to produce pigment; the result is gray hair. To cover up a single gray, swipe mascara that matches the rest of your hair onto it. (Or use a touch-up product, which is temporary color that comes in a mascara-like tube and washes out with your next shampoo.)
If you begin to see a larger smattering of grays throughout your hair, try adding volume when you style. Spritz some volumizing spray onto the roots of the gray sections before you blow-dry, or back-comb sections to get them to stand away from your scalp. "Flat hair makes grays even more noticeable," says Eric Fisher, owner of the Eric Fisher Salon, in Wichita, Kansas.
Quick tip: Get a cut with lots of layers. Fisher says, "It eliminates definitive parts and gives movement to the hair," both of which hide grays.
