Japan's veteran astronaut Koichi Wakata lived on the International Space Station (ISS) on a five-month mission from October 6, 2022 to March 12, 2023, setting the space duration record for an astronaut from Japan. His bags were packed with a supply of 3D Space Shampoo Sheets, a dry type of shampoo developed by Kao Corporation. The same sheet, now available commercially under the brand name Space Shampoo Sheet, can easily wipe impurities from the scalp and hair without water. A light massage of the contoured sheet over the hair removes excess sebum and refreshes the scalp.
