I don't know much about Indigo. I'm doing my girlfriend's hair tomorrow and she doesn't want the red highlights. But, since her hair is all black, and all I have is henna, she's willing to do a henna treatment tomorrow, and a henna/indigo treatment next time. I love looking at the pics of the different mixes on hennaforhair.com. I like the red, which is why I never looked into the indigo that much...but obviously, its a hot topic over a hfh.com.
Off topic, but I see the password to your fotki is Master Shake, lol. I'm assuming that you like Aqua Teen Hunger Force too
I love that show! My SO bought me the collection for my b-day.
