IU's short hair was real, not a wig.

Fans' interest has grown even more as IU revealed the process of personally cutting her hair into a bob. At first, there were reactions questioning if it was a wig, but it became a hot topic once her actual appearance with her long hair styled was revealed. Since it is a bob style she is showcasing for the first time in a while, it feels even more refreshing, and it seems to match the vibe of her new song well, revealing a new charm. As always, it is impressive how naturally she pulls off any hairstyle.
