Dyed my hair Ultra Light Ash Brown, what if I dye the same color again?

Question

I dyed my hair Ultra Light Ash Brown by Loreal's Les True Brunettes (or whatever) about a month ago, and I had dark dark brown and it came out a little bit lighter to a Dark ash brown but its still not light enough for me. If I dye it Ultra Light Ash Brown again, will it be lighter?

(&if it won't change, should I substitute the box's creme peroxide to my 30vol or 40 vol peroxide?)

Answer 1

it will either be the same color or be lighter

Answer 2

40 vol is good it will make the hair lighter...Good Luck

Answer 3

Where ever the dye still remains will be lighter as for your roots they will be another color your best bet is to try strand test cut some you hair out where it will not be noticed and see before you dye and keep your receipt because you can return the dye if the color of your strand isn't right or to your liking
