Asians a hair can withstand the weight of two eggs, hair growth each year can reach a total length of 16 kilometers,ghd outlet australia everyone probably will drop to 30,000 hairs per year, these secret about hair, you know how much?

Although the basic per a normal head of hair growth, but in fact a lot of people for the understanding of their own hair is very limited, a lot of people because they do not understand for hair health knowledge, resulting in improper hair care life will hair often appear one way or another problem.

The hair loss is widespread in modern society, largely because people are not comprehensive enough understanding of the hair, and so will lead to hair loss phenomenon showing a growing trend. Below, a good head hairnet combination of "crack the mysteries of the hair," recently held in China's Jiangsu exhibition is all about the hair that you do not understand!

Hair is what it looks like

First, we can look at the strength of the hair! The Asian hair hair is mostly the same, each hair probably be able to withstand the weight of two eggs, therefore, in theory, the amount of hair hair can pull the weight of two elephants!

Hair hair magnified a million times, you can see the almost its diameter and the wheels of the bus. Stand there, I really like the peripheral dyed black lacquer large stumps. "Stumps" on those one-block square "bark" hair hair flake. The hair hair dace piece is more intensive, more soft hair. In addition, many hair care products often publicity can fix the hair flake, but in fact, can not do only repair the surface of the hair because the hair care ingredients penetrate into the hair internal.

The outermost layer of the hair by the hair flake, their structure, like our Chinese roof tiles stacked staggered. "Texture" and structure, making the hair has good strength and toughness. Under normal circumstances, a dry hair be stretched by 30%. In the premise is not pulled off, a wet hair can be extended to 50%.

The hair itself is to have some flexibility and toughness, two thousand hairs can pull a weight of 30 kg; 200 hair can lift the weight of three kilograms; seven hairs even can withstand a weight of 100 grams. Therefore, in theory, a hair can pull two elephants. Just, human scalp can withstand the weight, this experiment can not try. Once scientists have done experiments Asian hair is the most "solid", only one hair hanging weights 140 grams, the hair will be broken; Europeans hair can withstand a weight of 111 grams, African hair You can only withstand a weight of 70 grams.

Secondly, we look at the hair growth cycle. The hair will and cell metabolism, and thus a hair can live up to three years, and it is difficult to grow to a certain length long.

Everyone's head, probably with 120,000 hairs, each hair are independent growth. Hair monthly growth rate is 1 to 1.5 cm. If a year down haircut, minus the 30,000 natural shedding off, even the rest of the hair up, can stretch for 16 kilometers. A hair can live more than three years, taking into account each month 1-1.5 cm long hair over 60 cm are special circumstances. "That we see in the news reports hair long to toes or hair grows over body height are considered special circumstances, even if the average person has never barber, hair is difficult to be more than 60 cm long.

The life cycle of the hair is actually consists of three stages: the first stage of the first of up to three years of active growth stage, this time does not exceed a maximum of six years; then a transition period,2012 GHD Peacock the hair will stop growing during this period, hair follicle atrophy; stable period of the last three months there will be continued, but the end of the stabilization period, the hair will fall off naturally. Number of our average daily shedding hair of 50-100 root year alopecia 30000, accounting for about a quarter of the total. But the reason why we have not become bald, because death and shedding hair regrowth. Usually grasping hair, there are hair falling down, falling hair root with white hair follicles, it has been "dead". But if it's roots transparent small particles, and some curled, described further in the "growth phase", falling down are "fratricide".

Once again, we come to know about the color of the hair. Under normal circumstances, the number of human hair, including melanoma, and thus the hair will be showing a natural black, but because of different race, will make the other color hair, generally more common Occidental!

Many people think that hair white melanin missing, in fact, is the the two melanin proportion decided hair, whether white, black, or yellow people, more than 95% of all dark hair, the hair There are two types of melanin, a true melanin, a brown melanin, the ratio of the two to determine the different color of the hair. White hair, is caused by the lack of melanin in the hair. Unfortunately, the reason for this situation is still unknown. White hair began to age, races and different. Africans about 44-year-old began to gray hair, Asians, about 40 years old, while Europeans average 34-year-old began to gray hair.

With white hair, a lot of people will choose hair color to change. The principle of hair color, in fact, is the first natural human hair melanin removal, re-infected with a new color, hair before becoming colorful. Observation enlarged to 100 times magnification under an electron microscope hair, it can be seen, in the hair dye is generated when each hair coloring and hair dyed a chemical reaction.

Then, our hair has a profound ability to "remember" and be able to record a lot of our lives, and even habits can be recorded.

Our hair's a seemingly slim, but in fact, it contains a huge information, scientists have found traces of arsenic in Napoleon's hair, so that he might be poisoned. While in hair tissue Egyptian King Hamlet Shas II, the experts found after he died 3000 years evidence can confirm that the king of Egypt has blond hair, white skin characteristics.

In fact, the use of hair a lot, not only in archeology play a role, in fact, the hair also plays a positive role in the area of ??judicial interrogation Secret key evidence or to see throu
