Why Ranveer Singh is wearing hat or caps all the time ?

Just a little question. I noticed that from past few months, Ranveer singh is being spotted always wearing some kind of hat or cap, I saw him in award function with hat then in his recent appearance in news and movie promotions.. everywhere he is wearing hat or cap .. what is the secret about his cap ?

Is he going through some hair baldness treatment ?

Here are some of the latest pictures of Ranveer singh from news sites:
