Abstract

Method and system for analyzing hair, predicting achievable end colors and recommending hair color agents based on recipient specific input. Includes methods for (a) identifying an achievable end hair color based upon at least one starting hair value of a recipient; (b) for identifying a hair coloring agent based upon at least one starting hair value of a recipient; and (c) for outputting an image for a hair color analyzing system. Also includes (d) a method for providing a hair coloring product to a consumer comprising the steps of: (i) identifying achievable end hair colors for the consumer, (ii) depicting the achievable end colors to the consumer, (iii) allowing the consumer to select a desired end hair color, and (iv) recommending to the consumer a hair coloring agent to achieve said desired end hair color.

Claims

1. A personalized method for identifying an achievable end hair color based upon at least one starting hair value of a recipient, said method comprising the steps of:

a) inputting at least one starting hair value of a recipient; and

b) identifying at least one achievable end hair color based upon said starting hair value;

wherein said identifying of an achievable end hair color is performed by a color prediction algorithm and further wherein said color prediction algorithm calculates said achievable end hair color using a color model generated by using a partial least squares regression technique of said at least one starting hair value.

2. The method of claim 1, wherein said starting hair value is calculated from the group consisting of values representing the reason the recipient is coloring their hair, how damaged the recipient'"'"'s hair is, what the eye and skin color of recipient are, what color recipient'"'"'s hair is, and combinations thereof.

3. The method of claim 2, wherein the color of recipient'"'"'s hair is indicated using values selected from the group consisting of Hunter L, a, b color values, and Commission International de l'"'"'Eclairage L, a, b color values.

4. The method of claim 2, wherein the color of recipient'"'"'s hair is measured by a colorimeter or a spectrophotometer.

5. The method of claim 2, wherein the recipient'"'"'s hair damage is indicated using values selected from the group consisting of values representing:

a) the recipient'"'"'s hair average hair length,

b) the frequency with which the recipient colors their hair,

c) the amount of damage determined by a method selected from the group consisting of;

i. intuitive self-assessment by the recipient,

ii. visual or physical assessment by the recipient or another,

iii. assessment using a device which measures hair damage,

iv. chemical assessment of the recipient'"'"'s hair, and

v. combinations thereof; and

d) combinations thereof.

6. The method of claim 1, further comprising the step of outputting at least one working image depicting the achievable end hair color, wherein the recipient may select said working image as a desired end hair color.

7. A The method of claim 6, wherein the L, a, b color values of said achievable end hair color are adjusted to correct for differences between the actual achievable end hair color and the recipient'"'"'s perception of the displayed achievable end hair color.

8. The method of claim 6, further comprising the step of recommending a hair coloring agent to achieve said desired end hair color.

9. The method of claim 6, wherein said working image is outputted to a display screen selected from the group consisting of a computer screen, a cathode ray tube device, and a liquid crystal display device.

10. The method of claim 1, wherein said steps are contained within a computer system or within a computer-readable medium or within a computer data signal embedded in a carrier wave.

11. A personalized method for identifying a hair coloring agent based upon at least one starting hair value of a recipient, said method comprising the steps of:

a) inputting at least one starting hair value of a recipient;

b) inputting a family color selection; and

c) outputting at least one working image depicting an achievable end hair color based upon said starting hair value and said family color selection,

wherein said outputting of at least one working image depicting an achievable end hair color is performed by a color prediction algorithm and further wherein said color prediction algorithm calculates said achievable end hair color using a color model generated by using a partial least squares regression technique of said at least one starting hair value.

12. The method of claim 11, further comprising the step of inputting of a selection of said achievable end hair color and recommending a hair coloring agent to achieve said selection.
