Zingiber zerumbet (L.) Roscoe ex Sm.,
commonly called Shampoo Ginger or Awapuhi, is a tropical, flowering plant from the ginger family (Zingiberaceae). Shampoo ginger is native to India
and has been introduced to the Hawaiian island through early Polynesian settlers.
The rhizomes of Awapuhi are used in folk medicine, while the clear slimy juice from the flower heads are used as shampoo or hair conditioner.
The flower heads reach a size up to 10 cm.
