A method for providing customized hair care cosmetics appropriate for an individual customer using a microprocessor having information on standard cosmetic material mixing ratios in accordance with scalp and hair conditions of consumers as a database, the method comprising the steps of:
- measuring scalp and hair condition of a customer, including the number of hairs, hair thickness, hair condition, pore condition, and hair loss state of the customer, using a diagnosis device, wherein the diagnosis device includes a camera comprising a plurality of lenses having different magnification from one another to be selectively utilized, the specific lens utilized depending on the specific scalp and hair conditions of the customer being measured, the lens used to measure scalp conditions being different from the lens used to measure hair conditions, wherein a significantly higher magnification lens is used to measure hair conditions in comparison to the magnification of the lens used to measure scalp conditions;
- comparing obtained images of scalp and hair conditions obtained by using the camera at selected magnifications to previously stored images to further measure and analyze scalp and hair conditions of a customer, said images of scalp conditions being different from the images of hair conditions and said images of the hair conditions being taken at a significantly higher magnification than the images of the scalp conditions;
- diagnosing the customer by interview and receiving the result of the interview diagnosis including information selected from the group consisting of hereditary history of hair loss, a time where hair loss occurs, shampooing interval, degree of current stress, existence or not of demodex follicularum, and details of disease of the customer and utilizing the results of said interview diagnosis including information selected from the group consisting of hereditary history of hair loss, a time where hair loss occurs;
- hampooing interval, degree of current stress, existence or not of demodex follicularum and details of disease of customer to diagnose and analyze scalp and hair condition of the customer;
- calculating a cosmetic material mixing ratio appropriate for the customer through the microprocessor, on the basis of information on the measured scalp and hair condition of the customer using:
- (i) the results of measuring the scalp condition obtained with the camera at a magnification appropriate for analyzing scalp conditions by comparing the images obtained by use of the camera with the previous stored images:
- (ii) the results of measuring the hair condition obtained with the camera at a magnification appropriate for analyzing hair conditions by comparing the images obtained by use of the camera with the previous stored image,
- (iii) said images of the hair condition being different from the images of the scalp condition and in the images of the hair condition being at a significantly higher magnification than the images of the scalp condition, and
- (iv) the result of the diagnosis by interviewing the customer to ascertain information selected from the group consisting of hereditary history of hair loss, a time where hair loss occurs, shampooing interval, degree of current stress, existence or not of demodex follicularum, and details of disease of customer, and
- by adding or subtracting a mixing ratio of materials that need to be adjusted depending on the scalp and hair condition and the diagnosis results to or from a standard cosmetic material mixing ratio previously stored in the microprocessor in accordance with the scalp and hair condition;
- and
- manufacturing the customized hair care cosmetics using the calculated cosmetic material mixing ratio to provide the customer with the manufactured cosmetics.
