I just found this link, and it sounds interesting!  Not sure if any of these work or not!  Has anyone tried these methods?

I know that lemon, honey, and chamomile all work, but haven't tried them myself personally. Sakina has been trying out honey and cassia, I know. And I believe she's mentioned trying chamomile. I've always been tempted by the chamomile, but like I've mentioned in other posts, I'm not willing to mess with my hair color again.  :-[

Beer and olive oil? I'm not so sure about these two, since a lot of people here oil with evoo and don't see a color change? All I know about beer is that is that its supposed to be a really great conditioner. At least, I've been reading about how great it is over the past few years.

Update: Did a quick check on beer. It looks like most people use it as a shine-enhancing conditioner, and nobody will verify that it highlights or lightens. Method to highlight with beer involves pouring a beer on your head and sitting out in the sun. My opinion is probably any lightening your getting from this is from the sun exposure, not the beer.  ;D

well the site says you have to be in the sun with the olive oil and to do it a few times over a few days. *shrug*
