Claim 0:
1. A system, comprising:
a sensor that detects one or more air-borne pollutants, including:
a metal-oxide, hybrid metal-oxide, electrochemical, MEMS, LED scattering, laser scattering, or fuel cell sensor; and
records an amount of the one or more air-borne pollutant as a voltage; and

a smartphone including:
wireless communication; and
a computer readable storage medium having stored thereon instructions that execute steps, including,
create a subject profile of a subject wearing the sensor, wherein the subject profile includes one or more of hair type, hair color, hair composition, and melanin type and content in hair;
communicate wirelessly with the sensor to read the voltage from the sensor and convert the voltage to a cumulative exposure to the one or more air-borne pollutant;
calculate a target exposure limit for the one or more air-borne pollutant, including adjusting down the target exposure limit using a combined exposure of the one or more pollutant and UV light at which a harmful hair effect occurs based on the subject profile, wherein the harmful hair effect is related to one or more of degradation of proteins in hair or loss of hair pigment;
determine whether the amount of the one or more air-borne pollutant exposure exceeds the target exposure limit;
provide a notification when the exposure exceeds the target exposure limit; and and
provide at least one haircare product recommendation to the subject, wherein the recommendation is a product including at least one of a UV blocker, a moisturizer, a humectant, an antioxidant source, a hyaluronic acid source, and a collagen source directed to repair the harmful hair effect.
