Device for measuring hair exposure to harmful light and recommending personalized haircare products
A computer system and the computer-implemented method of generating and providing haircare product recommendations to a subject. The method comprises determining, by a computing device, an exposure amount of light impacting a subject's hair; determining, by the computing device, a damage assessment of the subject's hair based on the type of light and amount of light exposure; and providing, by the computing device, at least one haircare product recommendation to the subject, wherein the recommendation is directed to repair damage to the hair provided in the damage assessment.
1. A system comprising a light sensor and a smartphone, comprising:
the sensor includes;
a UV sensitive LED that induces an electronic current proportional to UV intensity, wherein the amount of UV exposure is converted and stored as voltage;
the smartphone includes:
wireless communication; and
a computer-readable medium having stored thereon instructions that execute steps to:
read the voltage data from the sensor and convert the data into a UV-A dosage, and convert the UV-A dosage into a UV-B exposure using a pre-computed lookup table that gives the conversion factor as function of the column amount of ozone in the atmosphere and solar zenith angle;
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;
calculate a target exposure limit for UV-B 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;
communicate wirelessly with the sensor to determine an exposure amount of UV- B impacting the subject's hair when the sensor is scanned using the smartphone;
determine whether the amount of UV-B exposure exceeds the target exposure limit;
provide a notification when the exposure exceeds the target exposure limit; and
provide at least one haircare product recommendation to the subject, wherein the haircare product includes one or more of UV blockers, moisturizers, humectants, antioxidants, hyaluronic acid, collagen, and EDTA to repair damage to the hair.
2. The system of claim 1 , wherein the at least one haircare product recommendation is a personalized recommendation based on a subject's profile including styling methods used by the subject.
3. The system of claim 2 , wherein the subject's profile includes haircare products currently used by the subject.
4. The system of claim 1 , wherein the computer-readable medium further has stored thereon instructions that execute steps to track exposure amounts of IR and Blue HEV.
5. The system of claim 4 , wherein the computer-readable medium further has stored thereon instructions that execute steps to continuously integrate a total amount of exposure for each type of light impacting the subject's hair.
6. The system of claim 4 , wherein the computer-readable medium further has stored thereon instructions that execute steps to further determine the target exposure limit based on an airborne pollutant interacting with UV-B or determine the target exposure limit based on a sum total of exposure amounts of UV-B and one or both of IR and Blue HEV.
