Zingiber zerumbet (awapuhi), also known as shampoo ginger or pinecone ginger is a vigorous species of the ginger family.

As the flower heads mature, they gradually fill with an aromatic, slimy liquid and turn a brighter red color. The most common use of ‘awapuhi is as a shampoo and conditioner for the hair. The clear, slimy juice present in the mature flower heads is excellent for softening and bringing shininess to the hair. It can be left in the hair or rinsed out. Hawaiian women often pick or cut the flowerheads of
this plant in the forest, as they approach a pool or waterfall
for a refreshing summer bath, leave the flowers atop a nearby rock, and
then squeeze the sweet juices into their hair and over their bodies
when the swim is completed.
