Rocker Kim Tae Won surprised viewers with his radical style change on the latest episode of KBS's 'Qualifications of Men'.

As the 'Qualifications of Men' cast members were rounding up everything they had wanted to do over the previous year, member Kim Guk Jin said, "I've never permed my hair in my life. I want to do it," to which the members all agreed that they should do it together.

The biggest shock came when Boohwal's Kim Tae Won - known for his long hair tied back into a sleek ponytail - emerged with his hair in a bouffant mess, causing laughter among his fellow castmates.

However, the rocker himself was relatively nonplussed, saying, "It turned out better than expected. Definitely better than last week's hair."

What do you think - improvement? Yay or nay?
