Let's play a detective, shall we. Look at these two recent pics. Pic #1: Gray hairs spread throughout his head Pic #2: No gray hairs. If you look at these latest pics of Stern, you can notice that he clearly has at least TWO wigs. One wig has some gray hair and other wig is black/dark-brown. If you look at 1st pic, you'll notice how he has few gray hairs spread throughout his wig and how these gray hairs seem to be much 'rougher' hairs than his black hairs so they tend to stick out more (as you can clearly see in Pic #1). I don't know why but that pattern never made any sense to me. I did some research and it appears that when men get gray hairs, they almost always start at temples! But Howard has no gray hairs on his sidesâ€¦ only on the top of his forehead and top of his head. And gray/white hair clearly MUST be from a different person than black hair since it behaves completely differently from his black hair. Then I found this video of how wigs are made and it made PERFECT SENSE! Watch how this master wig maker makes wigs and how he adds highlights (replace pink for gray hair in Howard's case). He spreads these highlights throughout the wig! That's why Howard's wig looks so unnatural.
