http://thesleepaids.com/library/Sleepytime202065.jpg I had natural brownish/blond hair most of my youth. If you make this kind of tea up, 2 bags in a cup, pour it into a half bottle of your favorite conditioner. It would lighten my hair just right in the summer. For darker hair, you can add some henna to the mix. x
Honey and distilled water... I've heard good things. http://forums.longhaircommunity.com/showpost.php?p=134083&postcount=1096
use head and shoulders dandruff shampoo for awhile. when my hair was black it made it fade ALOT and then i bleached it to get it as light as it is now (red) and also i heard lemon juice is a great way to lighten hair but im not sure if its supposed to be natural hair, that hasn't been chemically altered... sun is really good too as mentioned before
