Magic Mixes
The Witchs' Brews page has Henna Page Artists' best, darkest mixes. These are safe, and they work! 

Then ...... there are "bad idea" mixes.

There are many other things you can use that seem like them might be useful.  Some don't do anything.  Other's hurt you. Why? Most dye and pigment molecules are too large to breach a skin cell, and not shaped the right way to bind with the keratin.  Other molecules are very small, and will  breach skin cells, but once they're inside your body they make you sick.

Bad Ideas Group #1
