There are few topics that matter more to men than hair and the shaving thereof.

When we’re young we rush it and start with the razor, most of us, long before we need to. Fast-forward 30 or 40 years, and most of us have decided that this task we once couldn’t wait to get to has become, quite literally, a daily pain in the neck.

But the neck is not quite the pain point involved in a new set of viral YouTube videos from Gillette, giving instructions in the art of manscaping areas other than one’s face: namely the head, the back, and yes, the… south forty, so to speak.

Five of the clips are animations, so kids, don’t bother going there for any anatomical insights.

Of the content, the public has decided that the art of grooming the groin is must-see video. It’s garnered almost 1.2 million views in the month it’s been posted to the Gillette “Go Further with Body Shaving” channel on YouTube. That compares to:

• 141,517 for “How to Shave Your Armpits”

• 102,942 for “How to Shave Your Chest”

• Just over 100,000 for “How to Shave Your Back”

• 49,841 for “How to Shave Your Face”

• Incredibly, only 46,876 for “How to Shave Your head”

So okay, I get the crowd appeal of the genital subject. It’s the same ground that Philips broke a while ago with its fruit-and-nuts iconography on the ShaveEverywhere.com microsite. But that was about using an electric trimmer; Gillette wants to teach you to do the job with a razor. And a multi-blade one at that. Yikes.

There’s a strong element of daredevil in watching even a cartoon shave down there– like seeing Evel Knievel jump the Snake River, only hairless and riding a razor blade.

But personally, I’ve been much more interested in learning more about shaving the head. I’ve long been on the lookout for signs of wear up there, and specifically for that hole-in-the haircut look at the crown. My hairline can retreat all it wants in front, but I’ve publicly vowed that when I start experiencing glacial melt up there at the north pole, I’ll shave that scalp clean.

But how to do it? I took that oath having no idea how to get it done. I could get a professional stylist to make the first cut, but not being a Mafia don, I’d eventually have to try to do it myself. I understand there are clippers that will do it; but they don’t seem to get the job truly done, trimming the hair down from fairway length but leaving a discernible putting green.

I don’t want putting green; I’m talking full-on bowling-alley smooth and waxed. Nope, a razor is required.

And the Gillette-sponsored video actually gave me useful information about the procedure—upstrokes, using moisturizer even on days you don’t shave—along with a certain amount of encouragement.

For the most part, razor marketing campaigns go right over my head, pardon the expression. They all seem to involve a ridiculous number of blades, some high tech like lasers or computer mapping, a bit of bad animation, and wind up with a hot babe. In fact, I had to check just now to see what kind of razor I’m currently using. (As it happens, it’s a Gillette, like 70% of American males.)

But this “Go Further with Body Shaving” has given me the modicum of useful knowledge I needed, and for that reason I’m more likely to remember it should the time come when I need to Zamboni the old dome. The clip strips out the extraneous stuff used to grab my attention on TV–the lasers, the babes, the cars–and just gives me what I want to know in about 60 seconds. I’m not sure that kind of association can be figured into Gillette’s marketing ROI; but it’s a real value to me.

Just one question that wasn’t covered in the video: Having shaved my head, what do I do if I find something weird up there in the till-now unseen regions? Like freckles that spell 666, or a birthmark in the shape of the Philly Phanatic?

Perhaps some forward-thinking hat maker should put out some companion videos: “When You’ve Gone Too Far with Body Shaving.”
