Of course, there's no one way to achieve flow, but that's also kind of the point. Any man on this follicle adventure has to endure calls to get a haircut, awkward hair days that only a beanie can solve, and a whole lot more shampoo and conditioner. The style also shows that a guy is committed to a cause, because a good flow can take months just to get started and plenty more to get to a place where it will impress, not confuse loved ones. And it's easy to see why: upkeep is minimal at best, a little extra hair always looks better peeking out of a baseball cap, and women seem to like it (just ask Brock O'hurn). Guys rocking some flowing locks has long been a badass move, endorsed by both grooming rebels (Jared Leto, Brad Pitt), athletes, and basically anyone in a rock group between the years of 19 (Jon Bon Jovi, Eddie Vedder, Axl Rose-the list is long). Some call it the 'lax bro cut.' Others refer to it as 'grungy.' We call it 'Bro Flow.' We're talking of course about the men's hairstyle that's taking over Hollywood.
