Thought the hairstyles for Girls' Generation's comeback was done and set?  Nope. Seems like they're still in their process of metamorphosis.

The girls are especially having fun teasing their fans through their personal SNS and giving them heart attacks.  Sooyoung in particular had a stage one phase of cutting her hair short, but she has now dyed it a shocking pink for phase two!  

She posted this on Instagram and Weibo with fans expressing their pleasant surprise at seeing this stylish, bold new look on her.  She is rockin' it with style, but what in the world does Girls' Generation have in store for their fans?  What concept is their comeback? The new hairstyles only raise more questions!
