In 2021 Tamil Nadu Legislative Assembly election, he contested on behalf of Makkal Needhi Maiam as a candidate for Virugambakkam Constituency.

[2] He received further acclaim in the early 2000s with his collaboration with Ameer and Yuvan Shankar Raja in Mounam Pesiyadhe (2002) and then for the "Kalyanamdhaan Kattikittu" song in Harris Jayaraj's album Saamy (2003).

[5] In order to prepare for his stint as an actor, he trained under stunt choreographer Power Pandian to practise action scenes and learnt salsa dancing.

[6] His next release, the crime thriller Uyarthiru 420 (2011), saw him appear in the lead role in which his voice was dubbed by Sanjeev opposite Meghana Raj but the film fared poorly at the box office and received negative reviews.

In regard to his performance, a critic from Sify wrote, "the chemistry between the lead pair is zero" and added, "though Snehan attempts and succeeds to be stylish in the songs, his wooden face, long hair, patchy makeup and dark glasses in almost every frame is a big let down".

The team began shoot in mid-2013 and planned to bring in actresses Shriya Saran, Sneha and newcomer Naatiya to play leading female roles opposite Snekan.

[10] In 2017, Snehan took part in the Tamil reality television show Bigg Boss hosted by Kamal Haasan and finished as the runner-up.

[12] He later announced that he would appear in the lead role in a film titled Panangkaattu Nari opposite his fellow Bigg Boss contestant, Oviya, but the project did not develop.
