I am 30 yr old Asian guy with salt and pepper hair. I stopped dyeing my about three years ago after painstakingly subjecting myself to this ordeal for 4 years. There are days when I like it (the youthful face and gray hair, I've been told looks quite good) but there are also days, more actually, when I hate it. I know I won't dye it black or a dark brown ever again but I'd like to know if there's a wash or a dye for graying hair to make it more even out? There's more gray hair on the both sides of my head than on top and short of dyeing the top white, what can I do? I have a thick head of hair if that helps. Thanks guys..
