Is Salman wearing wig ?

Today when i was surfing the internet for the latest happenings in bollywood, well suddenly to my surprise I saw someone with Katrina, well when I enlarge the picture it was none other than our Salman Khan and that too with thick hair. The event was the music launch of Katrina’s upcoming movie “Singh Is King” with Akshay Kumar.
Out of all the main attraction was surely Salman, as he was looking quite handsome as he used to look in his older days. What has Salman done with his hair ??? Is he wearing wig or has tried some hair treatment ?? All these questions must be arising in your minds after looking at pictures and it should arise as last time we saw him almost bald and now with thick hair. Well the answer will come after sometime and we will be able to know what Salman has tried. Till then the expectation is that he is wearing wig, as he used to wear wigs while shooting in movies.
