A photograph of her taken during the promotional shoot for the film Abaana (1958) appeared in the movie magazine Screen. It was then that Sashadhar Mukherjee, one of Hindi cinema's leading producers at that time, noticed her. She joined Mukherjee's acting school along with her debutant co-star Joy Mukherjee, Sashadhar's son. Ram Krishna Nayyar (R.K. Nayyar), who had previously worked as assistant director on a few films, directed this film. He also created her trademark look, called the Sadhana cut, inspired by British actress Audrey Hepburn. The Filmalaya Production banner thus introduced Joy, Sadhana and her iconic hairstyle in their 1960 romantic film Love in Simla. The film was declared a hit at the box office and was listed in the top 10 films of 1960. During this period she would again work under the same banner opposite Joy in Ek Musafir Ek Haseena.
