Aashritha was born in Madurai to a Tamil family. She had modelled for many print advertisements, while also winning the Vivel Miss South India’s Beautiful Face pageant and finishing runner up in the Miss Andhra Pradesh contest. Following appearances in beauty pageants, Aashritha made her acting debut in the low-budget village-centric film Isakki (2013), where she portrayed a teacher. A critic from The Times of India noted that "Aashrita makes a decent debut as a strong and independent woman who stands up to her father". In 2015, she played the lead female role opposite Ramesh Thilak in Vijay Sethupathi's production Orange Mittai (2015), portraying a town girl called Kavya. The film opened to positive reviews, but did not perform well at the box office.

Aashritha then moved on to work on Nagaraj's Azhahendra Sollukku Amudha, playing the titular role, after auditioning successfully for the film.
