Lightening hair with natural products (i.e. no dye)

[_Daisy_]

About a year ago I started looking on-line for DIY face and hair masks. One of them included honey as an ingredient. Now, my hair was originally a sort of medium to light/ashy brown (with sort of brassy blond ends from summer sun damage), but after using this hair mask about once a month or so for just a few months people began to comment on the red/auburn streaks in my hair. I'm not sure whether this is actually a result of this mask or just a bit of a strange coincidence, but I did stumble upon some on-line material that claims honey, cinnamon, chamomile, and cardamom can gradually lighten/redden hair.

Does anybody have any personal experience with these substances or know of any other natural/non-damaging ways (besides lemon juice) to subtly lift hair tone?
