If I go from light brown to darkest brown..?

Question

would it be deep deep darkest brown close to black OR would it be lighter?

Answer 1

If your natural hair color is light brown, and you WANT to make it darker, then choose a color that is 2 or 3 shades darker than your natural color. Now, if your hair has already been color treated, then it is much more porous than virgin hair and will grab the color much faster and darker. So, if you WANT to make your hair darker, choose a good quality shampoo-in 8 week color tint. This will lighten with every time you shampoo. But, in the event that you don't like it, don't worry--it'll be gone (or lighten up) in a week or so. The problem with choosing the very deepest darkest shade of brown is, as it gradually lightens, it also starts to turn red.  

Answer 2

that's not a very specific explanation....if your using a box color choose a shade that is a level 3 or 4. Anything lower then that will turn out black.
