So it is a very good material.
- the artificial hair made of polyamide fiber when attached to a wig, the artificial hair has a characteristic that, when time elapses, a plurality of artificial hairs stick together and converge. Therefore, it is necessary to repel the concentrated hair by brushing carefully each time.
- the polyamide fiber artificial hair has hygroscopicity like natural hair, when the humidity is high, the fibers tend to be in a bundled state due to the properties of the fibers. This tendency becomes more prominent as the humidity increases. For this reason, when polyamide artificial hair is focused by, for example, being wet in the rain or by washing and absorbing moisture, the wig wearer tries to prepare the hairstyle by combing the focused hair with a comb or brush.
- Nylon fibers behave like natural hair and fall on the wig base, whereas polyester artificial hair stands up and does not mix well with natural hair or nylon fibers, giving it a separated appearance. End up. This tendency becomes more prominent as the humidity increases. Nylon fibers sleep on the scalp like natural hair due to moisture absorption, while polyester fibers have higher bending stiffness and higher moisture. Since it is inferior in hygroscopicity, it remains in the state of standing upwards, so that natural feeling does not appear and wig wearing is easily recognized.

Since the bending stiffness value of artificial hair can be approximated to that of natural hair, it can behave like natural hair and have a natural texture.
