Hyoyeon of Girls’ Generation will be featured in the November issue of Cosmopolitan fashion magazine.

In released photos, Hyoyeon showed off her platinum blonde hair -- her signature hair color.

Hyoyeon changes her hair color often, as she is always trying out the latest styles.

In an interview with the magazine, she said, “The previous style -- ‘unicorn hair’ with rainbow highlights -- was nice, but it was hard to manage. So I came back with light blonde hair. The change certainly changed my mood.”

Hyoyeon also revealed her hair care secret. “A lot of people ask if I am worried about hair damage (due to the frequent dying),” she said. “I pay attention to my hair condition. I apply hair packs often for the scalp and hair.”
