Any other henna except mehandi?

I've been hearing all these great stories about henna and I feel like it's about time for me to also try it.
I noticed that pretty much everyone here orders henna from mehandi.com, but since I live in Germany shipping is a bit expensive..
Well my actual question is if the henna from mehandi is specially for natural hair or if any other henna here in Germany would also do the same'?
Thanks in advance

lumii, I order my henna from Sharika at http://butters-n-bars.com/henna4hair.html She is also a Curly Nikki member and offers members from this site 10% off on their orders, as long as you mention "curlynikki" in the coupon code area.

If you could give us some of the body art quality ("BAQ") brand names of the henna that is available in Germany, we may be better able to recommend a few. [You must be registered and logged in to see this image.]
