First, a little background on why there's such growing interest in men's grooming habits. The young men just entering the workforce are part of the millennials, a generation that will surpass baby boomers in sheer number for the first time this year. These 20-somethings care about looking good and, unlike some of their older brethren, don't feel that their masculinity is somehow threatened by the use of facial moisturizers, eye creams, and hair gels. Says Margie Nanninga, a home and personal care analyst with research firm Mintel: "These younger men are invested in looking good and are much more accepting of using grooming products to achieve that."  In fact, while U.S. retail sales of razors and cartridges actually ticked down a bit last year, according to Mintel, sales of men's skin care products grew by 8.4 percent and men's hair care products increased sales by 5 percent.  All this spells opportunity for these newer companies that are looking to grab a piece of an industry now controlled by Gillette and Schick, which together account for roughly 75 percent of the U.S. men's shaving market, according to consumer research firm Euromonitor.  Dollar Shave Club (DSC) founder and CEO Michael Dubin started his Venice, California-based online subscription razor company in 2012 when he figured he wasn't the only man in America tired of spending a fortune on razors. "I wanted to offer guys a better alternative than going to the local drugstore where razors are locked behind a cabinet and blades are far too expensive," he says.
