One of his first teachers found out his skill and encouraged him to painting. When he was thirteen years old, he emigrated to Cuba with part of his family. He received his first teachings at the Fine Arts College 'Concepción Arenal' at the Galician Centre in La Havana. In 1925 he came back to Galicia and got a grant in 1931 to study at the Fine Arts College in San Fernando. In Madrid he got in touch with intellectual people and artists of that moment. In 1933, he returned to Lalín and devoted himself to painting. In 1942, he moved to Vigo, where he stayed until 1951. This year he travelled to Buenos Aires because of an invitation to a collective exhibition. His works were very successful and stayed in Argentina until 1968. In 1969, he travelled to Amsterdam to see the selective exhibition to celebrate the centenary of Rembrandt.During the 70's and 80's he lived in Madrid.
After the war, he decorated the cinema 'Balado' in Lalín and made a mural for the Modern Cafè in Pontevedra, titled El manantial de la vida.During the period he spent in Vigo (1942-1951) he painted portraits of children (Merienda campestre, Juguete) and pictures of women such as Arquitectura. In his paintings El Amanecer or La Voz de la Montaña, Laxeiro recalls his childhood dreams and visions.He often painted masquerades characterising his figures in a grotesque way such as in Concierto, Flor, Hoy or Guiñol. Trasmundo is his most important work. In this picture, he shows his own interpretation of the great beyond.In the 60's he painted works such as Martirio y muerte del muñeco Ramón (1966), El Mundo (1964), La vieja caja de música (1962), Hans de Islandia (1966), Entierro aldeano, and so forth. We can also mention other works such as El verduguito, Los homenajes a Rembrandt, La duquesa Romea, Los dioses, El laranxo, or Pareja aldeana.
