Supporters of Darwin's theory can tell a lot about the fact that at the dawn of mankind, people were covered with thick hair. The ice age, the transition from monkey to man - there are many reasons. And those who do not really trust the English naturalist put forward a hypothesis about the appearance of man in the form that we know well. This is primarily about the vegetation on the body.
In men, it is known that more women are present on certain parts of the body and in small (except for the head) quantities. True, there are exceptions to this rule in the form of the appearance of hair in women on the face, back, chest, which, in principle, should not be. So what kind of “hair growth” in women can be considered normal?
Endocrinologist from the USA David Ferriman asked the same question. In 1961, he published his study of body hair growth in the fairer sex. 11 areas of the woman's body were selected where hair can grow, photos of these areas were compiled. The men were then asked to look at these body parts and rate them from zero - no hair at all - to four points - dense vegetation.
Later, Ferriman repeated the experiment, but the nine main zones of the female body were taken as a basis: the upper lip, chin, part of the chest, upper and lower abdomen, upper arms and legs (meaning part of the arms from hand to elbow and part of the legs from lower leg to knees), upper and lower back. And the rating scale has been modified.
Now it consisted of 15 numbers and was assessed: up to eight - normal hair, from eight to fifteen - moderate hirsutism, over 15 - moderate or severe hirsutism. This is how the Ferriman Gallway scale was born.
Hirsutism - increased hairiness in women, when hair grows where it usually only occurs in men: face, chest, back. Endocrinologist Tatyana Vasilyeva says that if this happens to a woman, it means that her health is not all right. Hormonal imbalance (often due to an increase in the male hormone testosterone in the female body), polycystic ovaries and their swelling, adrenal cortex lesions, problems with oncology - all this can cause hirsutism, the doctor says.
The doctor explains that such health problems can be indicated not only by the growth of hair in unusual places on the woman's body, but also by the growth of long thick coarse hair under the armpits, on the pubis, on the legs - that is, where a small amount usually appears "Frail" hairs. For example, acquired cannon hypertrichosis (rapid thick hair growth) may be a clear sign of a latent cancer.
By the way, the density of vegetation directly depends on the nationality of the woman. When Ferriman conducted his research in 1961, he took 60 white American women as a sample and based his conclusions on them. This was his mistake. In 2014, US scientists repeated this experiment, based on photos of female body parts from women of different nationalities and different skin colors.
It turned out that white women have the least amount of hair, and Asian ladies traditionally have the thickest "vegetation" on their bodies. However, ethnicity also played an important role. Thus, white Italians had more hair than white American women.
Tatyana Vasilyeva explains that the density of hair for women of one ethnic group and their almost complete absence (except for hair on the head) of another is the norm in both cases, since a comparison would be inappropriate here.
The struggle of women with extra hair is just a tribute to fashion, scientists say. It originated at the end of the 19th century, after Darwin published his theory. According to her, monkeys, turning into humans, lost the main part of their hair until they acquired a modern look.Less hair - more civilization - such a conclusion was made by many from this theory.
On its basis, even secondary racist ones arose, according to which, the more hairy the body of a particular nationality is, the lower its stage of evolutionary development.
The ladies immediately rushed to get rid of the "signs of backward nations." As entrepreneurial merchants began to do business with hair removal products, Gillette began its triumphant march. Meanwhile, scientists consider it a mistake to fight hair. Thus, they are sure, we deprive ourselves of the opportunity to choose the ideal partner for creating a family and giving birth to full-fledged offspring.
According to scientists, many centuries ago, it was by the smell of sweat that women and men determined how comfortable they were with such a partner. And sweat settles mainly on the hair.
Scottish scientists from the University of Stirling conducted a study. They asked ladies, whose age range was from 18 to 32 years old, to determine which of the men is most attractive to them by the smell of sweat on men's T-shirts. More than 60 women took part in the experiment. As it turned out, all the participants, without exception, chose those men who ideally matched them in terms of a set of genes. Three months later, the experiment was repeated, the result was the same.
Psychologist Craig Roberts, based on research data, concluded that the smell of sweat acts as an indicator of both health and genetic compatibility of partners.
Many doctors are sure that, getting rid of hair in all possible ways, we only injure the skin, causing cuts, “poison” it using various chemicals. And the method of laser hair removal is generally fraught with the onset of cancer.
