What is a hair tie made up of?

Elastic: The primary component of a hair tie is an elastic band. This band is responsible for its stretchability and ability to hold hair in place. The elastic material used can vary, such as natural rubber, synthetic rubber (like polyurethane or silicone), or a combination of both.

Covering: Typically, an elastic hair tie is covered with fabric or another material for comfort and aesthetics. Fabrics like cotton, nylon, polyester, or even silk can be used. The main purpose of the covering is to provide a smooth and gentle surface that prevents hair from getting caught or damaged.

Metal/Plastic Clasp (for certain types): Some hair ties incorporate a small metal or plastic clasp or button to secure the tie in place. These clasps help to keep the hair tie from slipping or coming undone while it's in use. However, not all hair ties have this feature.

In summary, a hair tie consists of an elastic band covered with fabric or other material, and sometimes includes a metal or plastic clasp for added security.
