Dye
For the majority of my life I have had black hair. I have always liked the way it looked on me, it made my natural pallor seem paler. Two years ago, I had unnatural red (awesome) hair but that was so hard to maintain: bleaching it every month and then dying it red again yeesh. So black was an easy option. Now, I am sick of black hair. I can't really do much about it at the moment. I could grow it out, which would take years. I could get it stripped which destroys your hair and costs a small fortune, I could bleach and then dye over it.
I think I will bleach it and dye it either the orange as seen above or a more natural (but still bright) red. I have had this black hair for almost two years, and it is time for a change I think. However, it is inevitable I will go back to black at some point.
