That is my hair right now! Not very nice and I want to dye it back to my natural color, as you can see at my roots, I was wondering if Clairol: Natural Instincts Semi-Permanent hair color would dye my brown/brassy hair to my natural dirty blonde?

Oops! Here's a picture of my hair now

I can't see the pic but SEMI PERMANENTS DO NOT LIFT HAIR COLOUR! THEY ONLY ADD COLOUR you will need HIGH LIFT Permanent to lift the roots
