What if I can't shave clean?

It's just an optical illusion to look dirty.

According to a new study in Scientific American, the ends of human hair tips are like pencil heads or javelin heads. After shaving, the stubble directly sticks to the hair follicle, leaving a stubble that looks thicker, darker and thicker than before shaving. Therefore, the coarser the body hair is shaved, it is probably just an illusion of the eyes.

The growth of beard is related to heredity and varies from person to person. Some people are born to grow fast, while others grow slowly.

It is also related to some life rules and eating habits. People who stay up late, people whose bodies secrete more androgens grow beards faster. If the amount of beard changes in a short time, it is probably because shaving time overlaps with the fluctuation of natural hormones in the body.

Extended data:

Use shaving cream or gel correctly, in the opposite direction of beard growth. Be careful not to make too much foam. Too much foam will hinder the sliding of the razor, resulting in minor cuts and burning pain.

Shave thoroughly and comfortably, and it is often difficult to clean the stubble at one time, so shave twice along the direction of hair growth. Using cream before shaving can make shaving smoother and more comfortable in the morning.

Use a clean razor. Always wash the shaver with hot water, thoroughly wash it under the tap and put it away to avoid dirt blocking pores. Replace the blade after 2~4 weeks of use, and do not use dull blades.
