Noh Hong Chul begun his first show as the permanent host of MBC FM4U Chin Chin on May 10th where he unveiled his shaved head for the first time since cutting it. Hong Chul said during the broadcast, "I hope to grow closer with listeners through this radio program. And to do that, I will have to reveal my secrets," where he immediately took off his cap, revealing his shaved head. Hong Chul had shaved his head last month after losing a mission on Infinity Challenge where he failed in his bid to reduce his weight. Despite shaving his head, Hong Chul did not dye his hair blonde. Netizens commented, "Really surprising, but it looks really suitable with him," "His hairstyle is really good looking. He certainly looks younger with it," etc. Hong Chul's debut episode yielded guests like Jung Hyung Don and Secret.
