When choosing to accent gray hair, choose highlight colors based on hair's natural color to brighten the face. The right colors keep skin from looking sallow and washed out.
Weave highlights and lowlights in shades of honey, tortoiseshell and mahogany into formerly brown hair that has turned a mousy gray shade. It is possible to stain the gray hair with vegetable-based hair dye or semi-permanent hair dye. This works on gray, which is normally hard to color, because it stains instead of coating the hair follicles. It also fades with several washings, so the gray roots do not stand out as sharply against the dyed portion of the hair.
