In an embodiment, the system comprises: a sensor for determining an item of hair condition information for a user, a memory configured to store the item of hair condition information, and a processor configured to update at least one item of hair condition information in the memory based on a discrepancy between an item of hair condition information for a user determined by using the sensor after a hair treatment and a predicted item of hair condition information for the user. ## Claims ### Claim 1 A system for managing hair condition information, the system comprising: a sensor for determining hair condition information for a user, the hair condition information comprising a degree of damage to the user's hair and a hair shade of the user's hair; a memory in operable communication with the sensor and configured to store the hair condition information; and a processor in operable communication with the memory and configured to update the hair condition information in the memory based on a discrepancy between the hair condition information for the user after a hair treatment determined by using the sensor and a predicted hair condition information for the user, wherein the processor is further configured to: compare the degree of damage to the user's hair captured by the sensor before the hair treatment with a plurality of degrees of damage to the hair stored in the memory; compare the hair shade of the user's hair captured by the sensor before the hair treatment with a plurality of hair shades stored in the memory; determine a closest degree of damage to the user's hair and a closest hair shade which are stored in the memory; based on the respectively determined closest degree of damage to the user's hair and the determined closest hair shade and the user's desired hair shade, to provide (i) a predicted degree of hair damage, (ii) a predicted hair shade, and (iii) personalized cosmetic hair treatment product information; and transmit the personalized cosmetic hair treatment product information. ### Claim 2 (depends on 1) The system as claimed in claim 1, wherein the sensor comprises a near-infrared spectroscopy sensor (NIR sensor) and a camera and a colour calibration device. ### Claim 3 (depends on 1) The system as claimed in claim 1, wherein the sensor comprises a near-infrared spectroscopy sensor (NIR sensor) and a photometer. ### Claim 4 (depends on 1) The system as claimed in claim 1, wherein the sensor comprises a near-infrared spectroscopy sensor (NIR sensor) and a sensor for visible light (VIS sensor). ### Claim 5 (depends on 1) The system as claimed in claim 1, wherein the system further comprises a display device for the presentation of at least information based on the item of hair condition information stored in the memory. ### Claim 6 (depends on 5) The system as claimed in claim 5, wherein the sensor is positioned in a mobile device and wherein the display device is positioned in the mobile device, in a smart mirror, or a combination thereof. ### Claim 7 (depends on 6) The system as claimed in claim 6, further comprising an application (app) configured to exchange information between the mobile device and the memory. ### Claim 8 (depends on 1) The system as claimed in claim 1, wherein the processor is further configured to determine a discrepancy between the hair shade determined using the sensor before a hair treatment or a predicted hair shade before a hair treatment and the hair shade determined by using the sensor after a hair treatment by means of a comparison of respective associated hair shade values. ### Claim 9 (depends on 1) The system as claimed in claim 1, wherein the processor is further configured to allocate the hair condition information for the user captured by using the sensor to the respective user in the memory. ### Claim 10 A method for optimizing a cosmetic counselling system, the method comprising the steps of: determining hair condition information for a user by using a sensor before and after a hair treatment, the hair condition information comprising a degree of damage to the user's hair and a hair shade of the user's hair; determining a discrepancy between predicted hair condition information based on the hair condition information for the user determined using the sensor before the hair treatment and the hair condition information for the user determined using the sensor after the hair treatment; and based on the determined discrepancy, updating, in a memory, the hair condition information used to determine the predicted hair condition, wherein the determination of the predicted hair condition information comprises: comparing the determined degree of damage to the user's hair with a plurality of degrees of damage to the hair that is stored in the memory, comparing the determined hair shade of the user's hair with a plurality of hair shades that is stored in the memory, determining a closest degree of damage to the hair that is stored in the memory, determining a closest hair shade that is stored in the memory, and providing a predicted hair shade based on the respectively determined closest stored degree of damage to the hair, the determined closest stored hair shade, and a predetermined desired hair colour, and based on the respectively determined closest degree of damage to the user's hair and the determined closest hair shade and the user's desired hair colour, providing (i) a predicted degree of hair damage, (ii) a predicted hair shade, and (iii) personalized cosmetic hair treatment product information, and wherein the method further comprises: transmitting the personalized cosmetic hair treatment product information to a dispensing station; and producing, in the dispensing station, a personalized hair treatment product based on the personalized cosmetic hair treatment product information. ### Claim 11 (depends on 10) The method as claimed in claim 10, wherein the method further comprises a comparison of the hair condition information for the user determined using the sensor before the hair treatment with the hair condition information for the user determined using the sensor after the hair treatment.
