Magaly Solier was born June 11, 1986 in Huanta, Ayacucho, Peru, which was the Peruvian region that during the 1980s and until 1993 suffered the most cruel and sistematic terrorist attacks executed by Shining Path. Those nasty times marked Solier's childhood. As a child in school, Solier was good in athletics, but once she reached high school, discovered her true passion was signing. In 2003 and 2004, she won the 10th and 11th "Seeking New Values" awards at the Ayacucho Song Festival in her hometown. After finishing school, she was discovered by film director Claudia Llosa, who was looking for an actress for her first film, Madeinusa. This film was a success in 2006 and launched Solier's acting career. The second film of Claudia Llosa, The Milk of Sorrow, in which Solier also starred, won the prestigious Golden Bear at the 2009 Berlin International Film Festival, as well as the Critic's Prize for Best Movie. In February 2010, The Milk of Sorrow was nominated in the Best International Movie category for the 2010 Academy Awards.
Solier recently released her first album as a singer, titled "Warmi" in quechua with themes composed by herself. She will next feature in Amador, the last film of Fernando Leon de Aranoa about immigrants living in Spain.
