Honestly I always use this product to dye my hair. Although the colors that I choose doesn't really cover the silverish gray hairs that I'm getting (which isn't that many)... but the color lasts pretty long. I've only used Khaki Brown and Sweet Orange and I actually love it. If you have "virgin black" hair like I did... it actually DOES show the color after your first use... then if you use dye it again every 3-6 months... the color actually shows more. I honestly change between the two regularly (sweet orange for summer and khaki brown for winter).
