The Sonora desert gets its name from the Sonora state in Mexico, where it covers a considerable extension of land, as well as in parts of southeastern California, southern Arizona and a big part of Baja California. Sonora desert has a extension of more than 100,000 square miles, and if you have had the privilege to be there you would understand that nobody would ever think anything that could effectively grow there could ever be used or serve any purpose, however this is not completely truth, Sonora desert is well-known to host both, rare plants and animal species worth preserving.
As a mirage in the middle of Sonora desert, one of these rare plants, a shrub known by the local O'dham people as Jojoba (Simmondsia chinensis), pronounced "ho-ho-ba", raised as a new hope for locals that benefited from the commercialization of the oil extracted from the seeds of Jojoba, used in cosmetic, pharmaceutical, dietetic food, animal feeding, lubrication, polishing and bio-diesel fields  as well as in toiletry as base for soaps, skin moisturizing oils against skin dryness and dandruff that can be used both, as an base oil for massages and directly into the hair and scalp.
But these are not the only health benefits of Jojoba and Jojoba oil, many more health benefits and some of the scientific research in which those ones have been based are explained in this article about the health benefits of Jojoba.
