First there's the dad bod. Now there's a spike in demand for gray hair. According to an article on Redbook, men are digging George Clooney's silver locks so much that they are getting their hair dyed gray.

The silver hair trend may have been started by female celebrities like Rihanna, Lady Gaga, and Pink—#grannyhair is even trending online—but the guys aren't far behind.

In a report released by online retail giant Amazon, there has been a whopping 80 percent increase in sales of gray hair dye. It seems that sporting the salt-and-pepper look is not simply perceived as just a natural part of the aging process, but a way to look wiser, bolder, and more desirable—just like Clooney.
