Claim 9:
10. A computing device comprising a memory and a processor, the computing device configured to:
maintain a first dataset characterizing a plurality of hair products, the first dataset including an identifier and water hardness reaction characteristic of each of the plurality of hair products;
maintain a second dataset characterizing an expected effect of physically combining each of the plurality of hair products with a hair type and a water hardness level;
receive, via a graphical user interface, user input associated with a user, wherein the input includes one or more of: hair type, location information, and desired hair appearance;
receive an image of used water hardness test paper, wherein the water hardness test paper includes a reaction region and a test paper identifier;
identify, based on the received image, a color or wavelength of light associated with the used water hardness test;
determine, based on the identified color or wavelength of light, a level of water hardness of a water source;
determine one or more of the plurality of hair products based on the determined level of water hardness of the water source, the user input, and the second data set;
adjust a chemical composition of at least one of the determined one or more of the plurality of hair products by adding one or more water-softening chemicals based on the determined level of water hardness and one or more acids to balance a pH of the respective hair product; and
provide the determined one or more of the plurality of hair products to the user.
