What is the difference between human hair and synthetic hair?

A human hair wig is longer lasting, soft and feels natural to the touch. It can be styled and dyed just like your own hair and "breathes" so your scalp won't perspire as much underneath. But human hair wigs need to be styled after every wash, and are more expensive because of its limited supply. A synthetic hair wig is easy to care for without requiring styling after washing, and is less expensive than human hair. However, it cannot take high temperatures, meaning it cannot be styled with an iron, and has a shorter lifespan if you wear it every day.
