What is Henna? What are Mehndi, Mehandi and all those other words?

Henna is the Arabic name of a bush of the botanical name, "lawsonia
inermis."  Leaves are harvested from this bush, dried and powdered to
make henna powder. The paste made from this powder, used to dye the
skin, is henna paste. The pattern on the skin resulting from the
application of henna paste is called a henna. If you have henna
patterns on you, you have been "hennaed". 

I had my drum hennaed a couple of years ago. I've been very pleased
with the results.

> I have used a sharpie pen, they come in a wide range of colors and it has not worn off

INK.
FW Artists Acrylic Ink is very good with great colors. Speedball is another good brand of acrylic ink.
Other permanent waterproof inks include Higgins, Koh-i-noor, and Dr. PH Martins Bombay India Ink. This last brand may be the best and is widely thought to be the most opaque. All these inks for use with pens, calligraphy brushes, air brushes, stamps, or whatever you can think of.
Except tattoo equipment... not for use in living skin. But it won't change
the properties of dead skin...
