IWRG Máscara vs. Cabellera (August 2016)

The IWRG Máscara vs. Cabellera (August 2016) show (Spanish for "mask versus hair") was a professional wrestling supercard event produced by Mexican professional wrestling promotion International Wrestling Revolution Group (IWRG), and took place on August 7, 2016 in Arena Naucalpan, Naucalpan, State of Mexico, Mexico. The focal point of the Máscara vs. Caballera series of shows is one or more traditional Lucha de Apuestas, or "Bet matches", where all competitors in the match risk their hair on the outcome of the match. The Lucha de Apuestas is considered the most prestigious match type in lucha libre, especially when a wrestlers mask is on the line, but the "hair vs. hair" stipulation is held in almost as high regard.

For the August 2016 Máscara vs. Caballera event the masked Canis Lupus put his mask on the line against Máscara Año 2000 Jr.'s hair in the main event. Canis Lupus was helped to victory both by El Hijo de Dos Caras and Trauma I both hitting Máscara Año 2000 Jr. with a steel chair. After the event Máscara Año 2000 Jr. was shaved bald while Trauma I and Canis Lupus both agreed to put their mask on the line at IWRG's next major show, Máscara vs. Máscara. In the semi-main event Trauma I defeated Mr. Electro to win the IWRG Intercontinental Heavyweight Championship. The show included four additional matches.
