Hi Suze,
Welcome to the forum. This is not a very popular answer for DIYers but I suggest that you go to a hairdresser to have it fixed. she (or he) can use a color remover and then re-color it in the shade that you want. She will also condition your hair so that it won't fade fast.
One more thing, cover your hair when you are in the sun. Sunlight will fade any haircolor.
