He got his first leading role in the 1994 film Madhosh which was produced by his father Tahir Hussain and directed by Vikram Bhatt. After a five-year hiatus he attempted his comeback appearing alongside his brother in Mela (2000). He appeared in several films that faired poorly at the box office and made Chand Bujh Gaya, Dushmani and Paltan. He also appeared in the TV serial Aandhi in 2003.
IBN reports that he was diagnosed with a mental disorder, and that his brother Aamir and his father were in a custody battle over Faisal that garnered much press coverage. Faisal's custody was awarded to his father Tahir in 2007.
