Shampoo Ginger, also known as Wild Ginger, Bitter Ginger and Pinecone Ginger, has thick bracts that are initially reddish-pink below and yellowish-green above, and bears white flowers that sprout from the bracts.

Eventually the bracts turn completely dark pinkish-red. This species of ginger has the botanical name Zingiber zerumbet, and in Thai it is known as kratheua.
