Abstract

According to an aspect of the present disclosure, there is provided a method of providing hair loss state information, the method comprising: obtaining a head image of a user; extracting a plurality of feature points from the head image, wherein the plurality of feature points include a first group of feature points and a second group of feature points; extracting a plurality of boundary points corresponding to boundaries of a hair and a forehead of the user from the head image; selecting a matching boundary point corresponding to the first group of feature points from among the plurality of boundary points; obtaining a top-face portion calculation value determined based on a distance between the first group of feature points and a matching boundary point corresponding to the first group of feature points with respect to a first axis on the head image; obtaining a middle-bottom-face portion calculation value determined based on a distance between the first group of feature points and the second group of feature points with respect to the first axis; and providing hair loss state information of the user based on a ratio of the top-face portion calculation value and the middle-bottom-face portion calculation value.
