In response to the growing demand for dry shampoos that can be used on the go, Japanese personal care giant Kao Corporation has launched a pair of dry shampoos under the hair care brand Merit, inspired shampoo sheet concept first developed for use in space. Day Plus Dry Shampoo is available in two forms – a spray and a sheet, both designed to clean hair on-the-go. The launch follows another intergalactic project, in which the brand was tasked with developing waterless shampoo sheets for use on the International Space Station.
