When choosing a wig, first make the size of the wigs the same as the wearer's head circumference. If it is too small, there is a sense of pressure, which affects the blood circulation of the head, causing headaches, dizziness, etc.; if it is too large, it lacks a sense of security. Based on the appropriate model, depending on the width of the forehead, wear it in an appropriate position. Wide forehead, long for the court, pull down the edge of the wig slightly when wearing, with a certain amount of hair curtain as a set; narrow forehead, the court is short, when wearing, the edge of the wig is slightly upward, but not too much , Set aside a small amount of hair curtains to set off.
