There is an opinion that the choice of a suitable time for haircuting hair should be determined by whether the moon will be decreasing or increasing on this day. We decided to check whether the moon in a certain phase can influence the speed of hair growth from a scientific point of view.
The number of "lunar haircut calendars" on the network is calculated by hundreds, and Publishing There are not only specialized Astrological resources And sections of horoscopes in news aggregators, but also sports And Lifestail, Women's magazines, Network of hairdressers, Cosmetics stores, retail chains, such as "The smile of the rainbow" And "Magnet". Recommendation You can cut yourself in a certain phase of the moon almost anywhere and in any language: from a large Kazakhstan or Ukrainian news portal to the site of the famous cosmetic brand Schwarzkopf.
Lunar cycle Played An important role in various ancient cultures, affecting agricultural practices, religious rituals and social norms. So, agrarian societies relied on the lunar calendar to determine the time of sowing and harvesting. In ancient Egypt and Mesopotamia, it was believed that various phases of the moon correspond to specific natural phenomena. For example, there They believedthat plant growth varied depending on whether the moon was growing or decreasing. In the period of the growing moon, according to their beliefs, the above -ground part of the plants grew better, while in the period of the decreasing, the root system developed better and the tubers were enlarged. This faith led to rituals aimed at coordinating agricultural activities with lunar cycles. Similarly with the leaves and flowers of plants: it was believed that the hair grows better during an increasing moon, and the haircut during the descending phase will be harmful - it will slow down or completely stop their growth.
The cycle of the life of the hair consists of Of the three phases: anagen, katagen and teenel. Anagen is a period of active hair growth, when the cells of the hair follicle are divided and the new hair is formed. This phase can last from two to eight years. On average, about 85% of the hair on the head is in this phase, which ensures their constant lengthening. Katagen is a short transition period, when hair growth stops and the follicle begins to contract in size. The hair located in this phase no longer receive nutrients. Katagen It lasts About ten days, only about 5% of the hair on the human head is on average in this phase. During the heterogene, the hair is at rest. They can fall out naturally or with mechanical effects (for example, while washing the head). Telogen continues About three months, and in this phase there is about 10-15% of all hair on the human head. After the body phase is completed, the follicle returns to the anagena, and the cycle begins again. Sometimes Select The fourth phase is an exogen, located between the heterogene and the anagen. In the four -phase classification, the stage is called that when new hair grows from a rested follicle, gradually pushing the old one.
Inflammation, stress, hormonal imbalance, malnutrition and side effects of some drugs Maybe To lead to the early completion of the anagen phase and the premature offensive of the teenter. In turn, a number of medications and a change in the diet can contribute to the speedy onset of Anagen and the extension of this phase. On the phase of anagen, last years, dozens of lunar cycles occur, and two or four cycles on a shorter bodyogen. Hair growth is happening Due to the division of the cells of his matrix - parts of the hair follicle. In general, in men, hair grows faster than women, younger ones - faster than the elderly, and thick hair grows faster than thin ones. However, throughout the whole anagen, if external conditions, lifestyle and nutrition does not change, hair Grows at the same speed (0.5–1.7 cm per month, or About 0.35 mm per day).
Supporters The ideas of haircuts on the lunar calendar explain their beliefs as follows: the moon affects the world ocean, causing ebbs and flows, and the human body is more than half of the water. Therefore, since the moon has an effect on liquids on the planet, it means that it must affect the human body. According to this analogy, soil waters rise and saturate plants, and blood in the human body accumulates in the area of the head. However, according to the Law of the World Bingle of Newton Luna attracts Not only water, but also any objects, including solid, causing both a change in the ocean level and solid -state tides - the curvature of the earth's crust at points from the side of the moon and the opposite to it. These changes are not large enough so that the human eye can fix them, but the GPS system Allows Track the movements of the earth's crust with an accuracy of centimeters, and the laser location of the satellites is up to millimeters. ” Therefore, the moon should be influenced equally not only on blood, but also on the solid parts of our body.
However, there is no scientific evidence that in certain phases of the lunar cycle, hair growth is accelerated or slowed down. The moon, like other celestial bodies, has a too insignificant effect on a single person. The force of attraction of the moon is 9 million times less earthly attraction, that is, it is negligible compared to other effects (for example, with the position of the human body and head or even with a height above the surface of the earth).
Since even theoretically explaining by science the connection between the speed of hair growth and the phase of the moon is absent, studies that controlled the hair growth rate of volunteers daily according to the lunar calendar could not be found. However, there are indirect data. So, in 1991, American scientists measured the speed of hair growth in male volunteers for 18 months. Researchers discovered Seasonal patterns: the hair grew the fastest in March, and by September this process slowed down to minimal values. In addition to the calendar months, the lunar months were also applied to the schedule of a percentage of hair in the growth phase. As can be seen from the figure below, there was no change in this parameter inside one lunar cycle (that is, the change of all phases).
In addition to the percentage of hair in Anagen, scientists tracked the amount of hair that has fallen and the thickness of the growing hair. These parameters also had seasonal fluctuations, but did not depend on the phase of the moon.
Thus, many parameters affect the rate of hair growth: constant (genetics, gender, hair thickness) and changed (seasonality, diet, level of certain hormones or medication). However, the phases of the moon are not among them. This celestial body is too far from us to significantly affect the matrix of the hair - that part of the hair bulb, which is responsible for the growth of the hair with its division. Therefore, to sign up for a haircut is based not on the phases of the moon, but solely from its own convenience.
