PURPOSE: A measurement method for a progress degree of hair loss is provided to perform a proper treatment according to the progress degree of the hair loss by accurately checking the progress degree of the hair loss.CONSTITUTION: The number of hairs is detected based on an image taken of a hair condition of a normal site(S10). An average thickness of the hair is calculated based on the image taken of the hair condition of the normal site(S20). The number of the hair is detected based on the image taken of the hair condition of a hair loss site(S30). The average thickness of the hair is calculated based on the image taken of the hair condition of the hair loss site(S40). The progress degree of the hair loss is measured based on the number of the hairs and the average thickness of the hair on the normal site and the number of the hairs and the average thickness of the hair on the hair loss site(S50).COPYRIGHT KIPO 2013[Reference numerals] (AA) Start (BB) End (S10) Detection of the number of hair on a normal site (S200) Sampling of the hair on the normal site (S220) Calculation of an average thickness of the sampled hair (S30) Detection of the number of hair on a hair loss site (S400) Sampling of the hair on the hair loss site (S420) Calculation of the average thickness of the sampled hair (S50) Measurement of a progress degree of the hair loss based on the number of the hair and the average thickness of the hair본 발명이 해결하려는 과제는 수학적 알고리즘을 통하여 탈모의 진행 정도를 정확하게 파악하기 위한 탈모진행정도의 측정 방법을 제공하는 것이다. 본 발명에 의하면, 탈모진행정도를 피측정자의 모발수, 모발두께 및 모낭수를 바탕으로 수학적 알고리즘을 통하여 수치적으로 산출하므로, 종래 측정자의 경험 및 눈짐작으로 탈모의 진행 정도를 파악한 것에 비하여 탈모의 진행 정도를 더욱 정확하게 파악할 수 있는 장점이 있다. 또한, 탈모의 진행 정도를 정확하게 파악함으로써, 탈모의 진행 정도에 따라 적절한 치료를 할 수 있으므로, 탈모를 효과적으로 치료할 수 있는 장점이 있다.
