Wow, thanks for the info!!!
I actually wanted to revive my brunetteness, and I was just doing a little bit of reading on hennaforhair.com and I guess by mixing henna, indigo and amla I can do that.

Yeah, I thought I should ask about the Lush stuff. It did seem a little bit weird having it in a brick when I was pretty sure henna was a powder.

I'm gonna go check out Henna Sooq and see what they have!
