The Locks Are Always Redder On The Other Head??

I have an addiction. I have an addiction to dying my hair. I've had every hair color you could imagine. I've been blond, brunette, a red head, and I even had black hair at one point. Every time I need my driver's license I have to provide a second form of identification because my hair color never matches. I don't even know what my natural hair color is anymore.

Most of the time I dye it because I just get bored or see a movie with a fabulous shade of chestnut brown or champagne blond that I absolutely must have on my head. Sometimes it goes too far. Usually when this happens it's red.

All I wanted was my highlights redone...but apparently once you have a little red in your hair and more is too much. Right now my hair color looks something like this...
I've been told that I have trouble knowing when enough is enough. Now I have to think how I'm going to explain this to my colleagues. I really need to give this up...or at least the red.
