Isidora Serrano smiles as her doctor gives her the positive results of a blood test in the cancer ward of the Luis Calvo Mackenna Hospital in Santiago, Chile. A renowned hair stylist offered to create a handmade wig for 14-year-old Serrano, who is undergoing chemotherapy to treat her bone cancer, as part of a program to help children regain their self-esteem and confidence during cancer treatment.
Workers Edith Marfil, left, and Marcela Reyes make natural hair wigs to be donated to girls undergoing chemotherapy. More than 300 of the wigs have been donated since 2009 by Italian-Chilean hair stylist Marcelo Avatte and his team.
Avatte says he was motivated to begin the project by the pain he felt when his own son lost his hair during chemotherapy.
