Chloe Grace Moretz's hair used to fall out from heavy extension use for movie roles.<br /><br />The 'Kick-Ass' star - who kick-stared her career in the US drama series 'The Guardian' at the age of seven in 2004 - has revealed that when she was 14 she was worried about experimenting with hair because she feared it would damage it.<br /><br />She said: "I had no hair underneath when they took them all out after filming wrapped. I was like 14 and terrified. After that I became so shy about doing anything with my hair."<br /><br />While that hasn't stopped her from dying her locks over the years, the 21-year-old model makes sure she follows a regime of not washing her hair too much and doing hydration masks to keep it looking healthy.<br /><br />
