Ever since SECRET's Ji Eun unveiled her solo concept's striking blue hair color, fans have been wondering whether the change was permanent or if it was just a wig. To fit with her title track's dark concept, Ji Eun's hair was dyed a bluish green that shocked fans for the contrast it drew with SECRET's "Shy Boy" promotions, which were concluded just a week earlier. In an interview with Newsen, Ji Eun revealed that her hair was in fact dyed and explained, "My hair was actually a color as light as Dalmatian's Youngwon. I bleached it to get to this color." When asked whether her hair had been damaged with all of the bleaching, she smiled and answered, "It's styled in a way that doesn't damage it." Source: Newsen via Daum
