I really wanted to have that awesome grey hair that is all the rage now, however, I didn't want to bleach my hair again in order to have it be a level 10. This product is the best thing ever if you are a lighter blonde but want that awesome grey color. I've used this product in two different ways, the first is following the directions on the bottle and the second is applying the product to bone dry hair and letting it dry on the hair. After that I'll rinse it, blot my hair dry and re apply, then blot again and style as usual. In the picture below my hair is around a level 8-ish (and I mean that loosely), I applied the product to dry hair, let it re-dry, rinsed it out, put it on again and this was the final color. I couldn't be happier. And the best part is that as my hair is fading, the grey will be different colors. Annnnnddd, there's NO DAMAGE to your hair with this product. If I could get Roux 10 stars I would, now I see why my grandma loves this stuff.
