I am a big fan of Grey's Anatomy and I love Kate Walsh's red hair. My hair is a medium brown and I do have some black spots from when I dyed my hair black over a year ago. Someone told me I would probably have to cut my hair to where the black is, but I do not want to cut it. I also want it to turn out the way Kate Walsh's is. How do I go about doing it? I really just want a dramatic change.
