Regarding the mechanism to promote hair growth, it was found that by the action of isosaponaline, sensitivity of "dentate receptor" receiving dermal papilla cells from the outside was increased, and the cells were activated. We also found that the number of proteins making capillaries for delivering nutrients and the like necessary for making the hair to dermal papilla cells increased.
In addition, the same effect and mechanism were observed in experiments in which "6-MSITC" which is a kind of pungent ingredient contained in the rootstock of this wasabi was administered to human hair papilla cells. The two ingredients that encourage this hair growth are peculiar to this wasabi, which is not included in the horseradish used in many of the tubes containing wasabi.
