The Boys Didn't Wear Hair Gel Before (Spanish:Los muchachos de antes no usaban gomina) is a 1937 Argentine historical drama film directed and written by Manuel Romero and starring Florencio Parravicini, Mecha Ortiz and Santiago Arrieta.

There is another version of the same name directed in 1969 by Enrique Carreras with a cast headed by Rodolfo Bebán and Susana Campos.

The aristocratic Alberto Rosales (Arrieta) falls in love with the blond tango dancer Rubia Mireya (Ortiz) leaving his fiancée (Córdoba).

[2] The film's title alludes nostalgically to the past, referring to an era before young men began wearing hair gel which was commonplace by the mid-1930s.

It marked the film debut of the actor and singer Hugo del Carril who quickly went on to become a leading star.
