Abstract: Systems for leveraging water quality data for the determination and recommendation of haircare products, services, and lifestyle decisions. A system configured for management of hair health of an individual includes circuitry configured to receive a measurement of one or more water quality markers that are relevant to the individual and compute, based on the measurement, whether a product or a service would advance the hair health of the individual toward a desired beauty outcome for a responsiveness metric; and circuitry configured to recommend or not recommend the product or the service to the individual, based on the responsiveness metric, such that the hair health of the individual is advanced toward the desired beauty outcome.

Abstract: Systems, devices, and methods for skin biomarker analysis and computation of predicted responsiveness to skincare treatments for management of skin health. A system is configured to receive a measurement of one or more skin biomarkers, compute a predicted beauty outcome that is predicted to occur due to a course of action, and recommend or not recommend the course of action, based on the responsiveness metric, such that the skin health of the individual is advanced toward a desired beauty outcome. Systems can recommend products, services, and other courses of action such as lifestyle changes, to improve the health of the individual.

Abstract: Methods for communicating risk of skin conditions due to exposure to sunlight and environmental conditions to individuals. Methods utilize geolocation data and environmental data to provide guidance and enable consumers to make informed decisions regarding outdoor activities, healthcare, and skincare. A photopollution metric is a function of ultraviolet index (UVI) and the level of a pollutant such as particulate matter (PM) and enables communication of risk of exposome-induced skin conditions to an individual based on environmental exposure.
