Girl's Day's Hyeri donated her hair to pediatric cancer patients.

On October 2, Hyeri introduced the topic of her latest YouTube vlog, saying, "Everyone, say goodbye. Today is the day I say goodbye to the long hair I've grown for 5 years. Actually, I've had the urge to cut it from time to time, but I'm finally cutting it today." The idol and actress seemed nervous before cutting her hair into a bob, and she worried, "I had a bob cut a lot in my early twenties. What if I don't look good with it anymore?"

She still made the move to cut her own hair with scissors before letting stylists take over, expressing, "The hair I had in the past will be donated to those who need it more than I do. I'm feeling a little richer."
