Ga In appeared on the March 12 edition of MBC's 'Weekly Idol' and revealed why she kept her hair short since her debut days.
According to an article in Soompi, she said, "I have really thick hair. If I grow my hair out, it should grow out like Jun Ji Hyun's straight hair, but it actually looks like a triangular kimbap. If I grow it out more than this, you can't see my shoulders.
"That's why I keep cutting it."
Jung Hyung Don said, "This look best matches Ga In."
Would you like to see her having long hair someday?
