Evening out the tone?

I only have myself and my general laziness to blame for this. I recently decided to go red after being white blonde for a bit. I slapped some 5 intense R/V onto my head. Viola! Super vibrant, intense R/V. Except this: half of my head is shaved, and my roots were starting to come in when I did it. So the shaved half is a little more copper-y, as are my roots. I'd like to even this out somehow without lightening my shaved patch or my roots. How could I go about adding copper-y tones to the super violet-y red parts? I'm open to all suggestions.
