Because your body thinks you're about to starve. Thousands of years ago,
hunger was a caveman's primary source of anxiety. When food became scarce, his
body coped with the resultant stress by releasing steroids, which were absorbed
by his omentum — a fat reservoir that hangs like an apron over the stomach —
and promoting fat storage. And since your body doesn't know the difference
between a demanding boss and a depleted herd of mastodons, your omentum will do
Don’t rush through a shave. That’s a good way to abuse your face. Instead, spend the necessary time prepping your skin for the razor.
Start by washing your face. Facial cleansers work best because they help soften the protein in the hair, says Jeffrey Benabio, MD, a dermatologist with Kaiser Permanente in San Diego. Harsh soaps, on the other hand, wash away hair-softening oils. Leave the cleanser on your face for one minute before you rinse.
Next, lather up with shaving cream or gel. (Benabio says it doesn’t matter which, but choose one labeled "for sensitive skin" if you need it.) Then let it sit for 2 to 3 minutes. You can comb your hair or brush your teeth to pass the time.
"That’s an important step," Benabio says. "That really softens the hair and makes a one-pass shave possible."
Dermatologist Adam Penstein, MD, agrees.
"The longer you let it sit, the better, although spending the time is not always practical," says Penstein, chief of dermatology at North Shore-LIJ Health System in Lake Success, N.Y.
Don't rely on your fingers to lather your shaving cream. Get a brush.
"A good brush really pushes the cream into the hair and makes it much easier to shave," says Penstein.
Benabio recommends using a badger hair brush for its ability to lift the hairs and really coat them with cream.
When it comes to razors, both Benabio and Penstein say there's no need to fool with multiblade razors. A single blade will work fine, though Benabio favors a double-bladed razor for his shaves. The important thing to keep mind, they say, is that the blade you use must be sharp. Discard it if you see a nick in the blade; otherwise, if you shave most days, change blades every week or two.
How often you must change blades is another good reason to stick with inexpensive single blades rather than three- or five-blade razors, which can be quite costly. The more expensive the blade, the less likely you may be to change them as often as you should.
As for straight razors, Penstein advises leaving those to the pros. "They're much harder to handle and to keep even," he says, "and they're not as safe."
Barber Charles Kirkpatrick says straight razors are a lot harder to use and that it's easy to get hurt with one.
"Some people say it's daring to use it, but I love the word safety, myself," says Kirkpatrick, an executive officer with Barbers International and owner of a barber shop in Arkadelphia, Ark.
