The top wave-shaped part of the clip lightly wraps around the hair and ensures that the pressure on the hair is evenly distributed. The bottom curved part of the hair clip, on the other hand, adapts to the shape of the head and is therefore very comfortable to wear and easy to release without feeling pain. This is simply because the clips do not have edges or elements that include metal. Less pain, fewer marks, and less damage - thanks to HAIRLOVETECH
