As we age, our hair starts to thin - and I'm not just talking about the hair on our heads. Eyelashes, which are already prone to sparseness, become even thinner. Knowing this, I assumed Demi Moore regularly used false lashes since her fringe always looks so full and lush. I was mistaken because I recently found out she's been loyal to the Lancôme Monsieur Big Volumizing Mascara for years. The actress previously told InStyle that she keeps her beauty routine "really simple" due to the fact that she has super sensitive skin.
