As shown in the example in FIG. 1, a bundle of hair is placed from the tip so as to be folded, and the curl is counted every half round of the curl. It is assumed that a beautiful curl is formed at a portion curled in the same direction as (forward rotation portion). A larger number of forward rotation points indicates that the curls are evener. According to the following formula, the ratio of the total number of forward rotation points to the total number of curl points of the tress is defined as the spiral rate. In addition, in the evaluation, the average value of the spiral rate of 5 bundles of tress was adopted.
