good post shave treatment.
Prep your beard. If you want a clean shave, you need to prep your beard adequately. The goal during beard prep is to soften your whiskers so shaving is easier and causes less irritation. The best way to soften your beard is to to shave right when you get out of the shower. The hot water from your shower should hydrate and soften your beard enough for shaving. If you haven’t showered, at least wet your beard with some hot water. A hot towel is a great way to soften the facial hair.
Lather up. Take a small dollop (about the size of nickel) of your shave cream and place it in a mug. Take your brush that you’ve pre-soaked with water and swirl the cream around until you get a nice thick lather. Apply the lather with your brush in swirling motions. When your face is nice and covered, take a few strokes to smooth everything out.
The shave. You don’t need to use pressure because the weight of the safety razor is sufficient to cut your beard. If you press down, you’ll end up hacking up your face. To help counter the tendency to apply pressure, try holding the razor by the tip of the handle.
Angling your razor is probably the trickiest part. The proper angle is somewhere between 30 and 45 degrees. To get the proper razor angle, put the top of the razor head directly on your cheek, with the handle parallel with the floor. Now slowly lower the handle until the blade can cut your whisker. Practice on your arm if you’re not comfortable practicing on your face.
While shaving against the grain can get you that smooth feel, you risk slicing up your face and causing ingrown hairs. When you’re first starting out, shave with the grain of your beard. If you lather up and pass the razor more than once over your face, you’re guaranteed to get a smooth finish.
The goal with shaving should be gradual beard reduction, not beard removal in one deft swoop. Most men try to get rid of their beard in one pass of the razor. This hack-and-go technique is what causes the majority of skin irritations. If you want to avoid skin irritation, lather up and pass your razor over your face several times. Your face will thank you.
