【英语时差8,16】怎么把胡须刮干净

 

In theory, shaving ought to be simple: the razor cuts the hair.   

In practice, it's not just a matter of razors and hair, there's also shaving cream to consider-- foamy¹ stuff that you smear² around your hairs before shaving. How come? Is shaving cream really necessary and, if so, how does it work?

 

While there's a wide variety of shaving foams³ available, some with perfumes or other chemicals for your skin, there's one thing that they all have in common: They're all wet, and this wetness is the key to their function. Wet hair is much easier for a razor to cut than dry hair is, because water makes the proteins in your hair soften⁴ and expand. While it's possible to shave with a completely dry razor, you probably don't want to try it--it's both painful and inefficient⁵.

 

The best way to use shaving cream is to apply it, then wait a couple minutes before shaving. This is because, while wet hair is good for shaving, completely saturated⁶ hair is even better. It takes about two minutes for the hairs to soak all the way through. This is a good reason to use shaving cream, instead of just wetting your face with water. The foaminess of the cream helps hold the water in place long enough to soak in.

 

For an electric razor, of course, you shouldn't use shaving cream. Electric razors shear⁷ your hairs off, snipping⁸ them like tiny scissors. This works best on brittle⁹ hair that's pointing straight out, which is why electric shaving lotions¹⁰ contain alcohol to dry the hairs and make them stand straight.
