Sam Smith has nothing to hide anymore, bravely opening up about their insecurities, including hair loss, in a video for Vogue about beauty secrets. The “Diamonds” singer revealed they underwent hair transplant surgery after a receding hairline that started two years ago. “My hair … it’s been a touchy place for me,” Smith said in the video posted on Tuesday. “I haven’t actually spoken about this before, so I’m gonna speak about it because I don’t actually feel like I have anything to hide.”
