Method and System for Cognitive Hair Dye Prediction

The method and system here described proposes to use a cognitive engine to exploit data collected from past experiences of hair dye for predicting results.

Considering that to treat hair is typically not inexpensive, is time consuming. Furthermore the chemicals employed in these treatments could be caustic, may damage the hair and may be dangerous for people allergic to the ingredients. It may be useful to know in advance the hair dye result before undergoing a hair coloring.

Hair is mainly made of keratin, the same protein found in skin and fingernails. The natural color of hair depends on the ratio and quantities of two other proteins, eumelanin and pheomelanin. Eumelanin is responsible for brown to black hair shades while pheomelanin is responsible for golden blond, ginger, and red colors. Human hair has a large spectrum of different colors: light, dark, plain or freckly skin; black, brunette, blond, auburn, and white hair. Most of this color is attributed to a single class of pigments: the melanins.

The method and system here described allows, by knowing the amount and composition of these molecules in the hair, to produce a preview of the result of a coloring operation on the hair when a specific treatment is applied, using a specific product. A "hair color simulator" simulates the chemical reaction between the hair's molecules with several kind of chemical reagents. The result is elaborated by a "cognitive engine" that will provides suggestion about the possibility of allergies to the selected chemicals products and in addition to suggestions about the current fashion.

An optical screening of the hair (the Spectrometric Screening technique exist) allows to determine its physical property and chemical composition and can determine the concentrations in the hair and the distribution of the different melanins in it. As a matter of fact, melanins (eumelanin, pheomelanin and neuromelanin) in the hair which serve as pigment, have different chemical and biological responses as they behave differently when exposed to light: the monomers and oligomers components making up the melanins show variable abilities to absorb light and the melanin particles have variable abilities to reflect and scatter incident light for different wavelengths. This information is used to prepare the color's prediction.
