I use the haircolor products because they do not damage my hair and have no ammonia or other obnoxious smell. I have short dark brown hair with lots of grey and white, so I mix this with equal amount of 4N - chestnut. Need the chestnut to penetrate the grey and white because the copper chestnut alone will eventually turn the grey/white hairs pink. Also use the conditioner and shampoo. Because my hair is short I use 3 caps of each color and then 6 caps of the developer, so I get 2 to 3 colorings per box. Love these products and highly recommend them.
