It's not known why Madhavan is growing his facial hair, but he is certainly finding it a tedious job.
"Oh man, how do people manage facial hair? I am going crazy here," posted Madhavan on his Twitter page.
"I went around the whole day wondering why the whole house smelt of mangoes, only to realise my son had applied some mango pulp on my moustache. Plus now, along with my long hair, I have to groom and trim the face too," he wrote
"(I'm) totally not used to this. Hats off to all the bearded dudes, man," he further posted.
Known for films such as "Alaipayuthey" and "Rang De Basanti", Madhavan had sported long hair in Tamil films "Thambi" and "Priyasakhi".
He even twirled a moustache in Tamil political-thriller "Aaytha Ezhuthu".
The 43-year-old was last seen in 2012 film "Jodi Breakers" opposite Bipasha Basu.
