John Cena wished he had gotten his hair transplant even earlier. Cena, 48, opened up about his hair thinning with age while chatting with People in a cover story published on Wednesday, August 6. While opening up about aging, Cena admitted that he tried to "hide [his] hair loss" at first, but WWE fans kept "bringing it to light." "I saw their signs that said 'The bald John Cena,'" the actor recalled. He explained that trolls were the ones who "pushed" him to see what his options were to help thicken his hair.
