Why isn’t this Shampowder for guys, too?

Upon reading about Shampowder today, I’ve gotta ask - why isn’t there an option for guys here? I’m sure if I started digging around I could find a version that doesn’t have pigments or vanilla scents, but why start elsewhere when the fine folks at Buttercream Cosmetics have clearly figured out a way to make it work for the female population?

Let’s take this as my official declaration that Shampowder for guys would have to be a popular item, maybe even taking part in the college shower phenomenon.
