Life small Popular science-often shaving hair will not make hair more and more coarse

In fact, shaving often does not make them thicker, harder, or grow faster. Unlike their parents ' admonitions, there has been a series of scientific evidence since the 1920s that your hair is not long and growing, and that it has nothing to do with your scraping.

In fact, hair growth is entirely controlled by subcutaneous hair follicles. The scrape is actually just the outer part of the whole hair that has been "dead", so these hair follicles are not affected by scratching. So, hair color, weight and growth rate is determined by the subcutaneous hair follicle, and you do not scrape any relationship.

And how long has this misunderstanding existed? According to the New York Times, it has existed for at least 50 years.

In addition to listening to parental warnings, one of the big reasons people believe this fallacy is that each time they come out, they feel thicker than they were before, but they don't. If so, that long shave, or other parts, is not the place will become unsightly?

In fact, it's just a sham to feel thicker and more hairy. And why? For example, a branch of slender, it flexibility is very good, you can bend freely. If you cut off a paragraph, it will feel harder and thicker. This is the same as body hair.

Some people think that the hair will grow more thick. Not really. If so, it would be a white beard and a black beard. Again, it is the subcutaneous hair follicle determines how long hair, and scraping does not have the slightest relationship. One of the big reasons for this misunderstanding is that, after a few years of adulthood, the beard is thicker than the first shave, which is thought to be a long-term shave. In fact, this is just the result of natural growth.

The misconception that shaving affects one of their growth rates is not much different from the previous two. Hair growth is determined by hair follicles, not scraping. People would think that after the first shave, the beard grew not fast, but grew much faster in adulthood. So I think it is often scraping to make them grow faster, coupled with the original parents of the warning, more convinced. It's like thinking that the sun is rising every day because the alarm you set up is ringing.

However, hot wax removal can really affect hair growth. Not thicker, more stout, but quite the opposite. Long-term hair removal will damage the health of skin follicles, resulting in lighter hair color, thinner, more difficult to grow.

The General people also think, often comb hair is beneficial to growth, actually is harmful. When combing the hair, it is likely to pull out the growing hair, or it may break the hair and damage the scalp. So, try to comb as little as possible.
