Hi mj!
You're very welcome!
The season for Shampoo Ginger is just starting here. The wild Hawaiian 'Awapuhi does spread fairly quick in forest understory and is somewhat aggressive in a garden (although it is a pleasant amenity to massage into hair after showering).
I have a patch of the 'Darceyi' cultivar and it has pretty much stayed where I put it since 1997. It's easy to take care of and provides the conditioning gel just as well as the wild plant!
When the patch matures I'll get some photos and add them to the database as well.
Aloha, Dave
