Nanda was known to encourage newcomers. She signed eight films with Shashi Kapoor at a time when he was yet to become successful in Hindi Cinema. Their first two films as a pair – the critically acclaimed romantic film Char Diwari (1961) and Mehndi Lagi Mere Haath (1962) – did not work, but the rest were successful at the box office. Shashi, though he had achieved success in English films in 1963 and in two Hindi films in 1965, had five flops as solo lead hero from his debut in 1961 till 1965 in Hindi films. In Jab Jab Phool Khile (1965), Nanda played a westernised role for the first time and it helped her image. Her favorite song that was famously picturized on her in the film was "Yeh samaa." Shashi would later declare that Nanda was his favorite heroine. Nanda, too, declared Kapoor as her favourite hero. In the period 1965 to 1970, the successful films of the pair Shashi-Nanda include Mohabbat Isko Kahete Hain (1965), Jab Jab Phool Khile (1965), Neend Hamari Khwab Tumhare (1966), Raja Saab (1969) and Rootha Na Karo (1970). In the early 1970s, Nanda suggested Rajendra Kumar, co-producer of The Train, to take Rajesh Khanna as the main lead.Profile, indiawest.com. Retrieved 29 March 2014.
