I put a little Preference Red Penny in my Preference Lightest Auburn for a boost.
Oh boy. Streaky and so bright and ugly.
So I re did with Preference Light Auburn.
Now I have that horrible Burgundy color with red penny at the roots.
My daughter bought me a hat!
I need a better solution.

You need to go a professional hair salon.

Do not attempt to fix it yourself, you could end up making matters worse. I recommend that you go to a salon and have them do a corrective color. They will be able to match your natural hair color as close possible or achieve your desired color.
