Natural coloring to lighten hair?

what is a natural way to lighten hair?

i have naturally black hair and i would like it to be a dark brown

sun dosnt work

There is nothing else but sun+lemon-juice+chlorine that will naturally dye your hair for you, so if sun doesn't work, try lemon juice on it and go to the pool a lot. But other than that, there is nothing that can naturally dye your hair.

try sitting out on the sun but rub lemon through your hair..and swim in pools alot

putting lemon juice in your hair and going out in the sun would but i dont know how much it would lighten

Lemon juice + sun + chlorine
