In 2008, Aragón Castillo became the party's secretary general, its second-highest position, holding the job for three years.

After making a failed bid in 1997, the PRD sent Aragón, representing the state of Nuevo León in the second region, as a proportional representation deputy to the Chamber of Deputies for the LVIII Legislature between 2000 and 2003. She was a secretary on a special commission that followed the investigation of femicides in Ciudad Juárez and sat on a range of others, including Public Education and Educational Services; Justice and Human Rights; Population, Borders and Migratory Matters; Attention to Vulnerable Groups; and Science and Technology.

In 1995, Aragón became the head of the PRD in Chihuahua, a position she held for two years, and a national party councilor; she also founded women's organizations within the PRD, serving as its delegate to Socialist International Women from 1998 to 2003 and its women's secretary from 1999 to 2000. She also sat on a 1996 commission that reformed Chihuahua's constitution and state electoral law. In addition, in 1996, Aragón helped to found the Foro Nuevo Sol, an internal political faction within the PRD.

Aragón primarily spent the early 1990s learning, as she almost completed a degree in anthropology from the National School of Anthropology and History; she served on the Chihuahua unit's student council between 1992 and 1995. She would also obtain a master's degree in Educational Development from the Chihuahua Graduate Center.

Aragón Castillo has a lengthy history of socialist activism and teaching. She joined the Mexican Communist Party in 1976, when she served on the student council of the Rural Normal School of Saucillo, Chihuahua. At the same time, she joined the United Federation of Rural Socialist Students of Mexico. In 1980, she graduated from the Regional Normal Education Center of Aguascalientes as an accredited primary school teacher, and in the mid-1980s, she added a technical degree in Mexican Folkloric Dance and a degree in Middle Education — Social Sciences from institutions in Chihuahua, beginning a 29-year teaching career. Meanwhile, she joined the Unified Socialist Party of Mexico and its successor, the Mexican Socialist Party, and upon the foundation of the PRD in 1989, she joined that party.
