Hair stylist Marcelo Avatte (R) prepares to fit Isidora Serrano, a 14-year-old who lost her hair due to chemotherapy to treat her bone cancer, with a natural hair wig in the cancer ward of the Luis Calvo Mackenna Hospital in Santiago, October 23, 2014. The wigs, handmade by Italian-Chilean hair stylist Marcelo Avatte and his team, have helped the children regain their self-esteem and confidence during cancer treatment. Renowned for making customised wigs, Avatte has donated more than 300 wigs since 2009 and says he was motivated to begin the project by the pain he felt when his own son lost his hair during chemotherapy.
