A computer system obtains digital image data of hair of a live subject; provides the digital image data to a style recommendation engine of the computer system; determines, by the style recommendation engine of the computer system, color of the hair of the live subject based on the digital image data; and executes a machine learning model of the style recommendation engine using the color of the hair of the live subject as input to generate a style profile as output. The style profile comprises parameters configured to control discharge of one or more components of a hair coloring formulation by a formulation dispensing system of a hair coloring device.

An online system accesses a database that stores information on hair coloring products from multiple brands. Users upload an image of their current hair condition and specify a desired hair condition. A machine-learning model assesses various hair attributes, such as current shade, tone, texture, and porosity level, based on the uploaded image. The system employs a decision tree based model to analyze these attributes that characterize the current hair condition with the desired hair condition to determine a hair color treatment. Based on the hair color treatment, the system determines a specific hair coloring formulation, including products from one or more brands, the ratio between these products, and the application time required to achieve the desired hair condition. This formulation is then displayed on the user's device.

The invention relates to a hair dye based on monatomic nano-enzyme, the hair dye is composed of a first solution and a second solution which are independently subpackaged, the first solution is a solution containing melanin small molecule precursor substance 5, 6-dihydroxyindole and monatomic nano-enzyme, and the second solution is a solution containing hydrogen peroxide; the monatomic nano enzyme is nitrogen-doped hollow carbon microspheres loaded by metal iron, copper, manganese or silver atoms.
