Hi,
For about two years now I've been dying my hair. I went from strawberry blonde to dark brown, to red on top brown underneath (twice), to purplish red all over, to red with blonde bangs, to highlighting my hair with bleach until it was almost my nat color again, then back to red which faded to the brownish color I'm at now. My hair was once past my chest slightly, but after months of convincing my dad it's now at a line cut with the longest side being at my jaw. My dad told me that I can't dye it anymore. (Probably a good thing.) Since I'm only 13 I can't quite argue with him, but my roots are driving me crazy! Is there a way to get my color back without constant cutting? And if not how long will it take to finally grow back?
Thanks.
