How to naturally lighten dyed hair?

i have strawberry blonde hair. over the years its faded to a dirty blonde with natural highlights. i dyed my hair brown. on the box it showed itd be a light brown with redish tints in it. it came out far to dark with no red. i hate it. i heard if i wash my hair with dishsoap like dawn dishsoap it can help strip the color out. i know thats damages your hair but i need the color out. will that help? what are other natural ways besides lemon juice?
