Sulli returned to long hair.

Today, f(x) Sulli posted on her me2day, "My hair is long" along with a picture. In the picture, Sulli has long hair, showing off her feminine beauty.

Internet users who saw this commented, "That's not your real hair, right?," "Long hair is the best," "You looked cute in short hair too," and "You look calmer and more reserved with long hair."

Sulli had short hair for a period of time for SBS drama "To the Beautiful You."
