Hey guys just my opinion! If shlok was clean shaven he wont look grey / and now dark! Also both CVs and avi himself perhaps like the look, makes him look more mature and someone who can actually run a big business and be clever cunning at the same time like his babaNow look at the pic below, shlok does look ruthless bcoz of stubble. Granted baba has no beard and perhaps that is why his EYES do the job of this horrible character niranjan ... 2c!
Yeah it seems to be for his character I understand that more dark etc.
