Hair says it all!
In the history of mankind, hair has always been a symbol of prosperity, beautiful. It was also believed, that they have a magical meaning and are a source of strength.
Today, hair is also the source of answers to many questions. New methods of DNA research will tell us why mammoths became extinct and what is the origin of the human races. And in the future, they may play an even greater role in investigations and investigations.
“Until now, you had to drill into old bones if you wanted to compare the genes of a mammoth and an elephant, or to see how they faced the Ice Age before extinction. Usually, the DNA found was also insufficient and contaminated. But the DNA in the hair is very pure because it is surrounded by keratin, a kind of plastic membrane, which protects the hair and the DNA itself. Think of all the extinct and hairy animals in museums around the world. We have a lot of work ahead of us, ”says Thomas Gilbert.
The research focused on the mitochondria. It is a kind of cellular power plant and is perfect for comparative research, both humans and other mammals.
Professor Eske Willerslev, who is an expert in finding traces of DNA in sediment and organisms and who also discovered the oldest living bacteria is enthusiastic about the new method.
“New research methods are related not only to the past but also to the present, for example in forensics. Of course it takes time, so that they can develop and give 100% certainty in any case. Obviously, a certain amount of hair is needed, which is not always easy to get at a crime scene. However, it is a matter of time and improvement. Another advantage is the fact, that this method can be assisted by very quick, modern sequencing machines and the results will be available the next day " – says Eske Willeslev.
Thomas Gilbert collaborated with employees of numerous universities and research centers, including those from the USA, Russia, Belgium, France and Sweden during the development of this method.
Is baldness a disease of the 21st century?
Unfortunately, thorough scientific research has not yet been carried out, which made it possible to unequivocally confirm this thesis. Japanese researchers found, however, that in their country the number of people losing their hair has increased significantly since the Second World War. To the question, what's behind it, they tend to change the way the Japanese eat, that occurred during this period.
It is related to the Western diet, in which you eat more meat rich in saturated fat. This has the effect of raising cholesterol levels, which results in baldness. So far, there are no studies that would ultimately confirm this hypothesis.
It is certainly true, that the deteriorating quality of life, accompanying I have constant stress, smoking tobacco, poor diet and environmental pollution are factors that contribute to hair loss. They can significantly speed up this process and make it more intense, even, if the direct cause of baldness is genetic determinant.
The Italian prime minister is known for his crude behavior, passion for luxury, beautiful women, plastic surgery and… bald patches, which she carefully hides.
Italians love to laugh at their prime minister and any reason is good for them. A few years ago, Berlusconi had a hair transplant operation.

Unfortunately, this word is foreign to Berlusconi, therefore, it often comes with an unnatural hairstyle that resembles freshly laid asphalt, which becomes the theme of jokes.

The world's first "green" hair dye
If you love to dye your hair and you feel and look better, then you have remorse, knowing how it affects the environment - never again.
Japanese scientists have invented an environmentally friendly alternative to traditional hair dyes. Their invention is also devoid of side effects, such as the need to re-dye frequently and the possibility of skin irritation and hair damage.
Every year, millions of people lighten their hair with products containing oxidants. The paint contains hydrogen peroxide, which is extremely effective in removing the pigment that gives them dark color. However, you usually have to reapply the paint every few months, which can weaken the hair.
The new hair dye is made from a mushroom variety, which purifies the earth. It naturally replaces melanin and other dark hair pigments, not having the same side effects as hydrogen peroxide.
Research author, Kenzo Koike of the Kao Beauty Research Center in Tokyo, says, that this enzyme could be added to traditional hair dyes, to avoid weakening them. Despite this, small amounts of hydrogen peroxide will still have to be in the new paint, because it is necessary for the operation of the product.

Siwienie można odwrócić
This is good news for people, who have gone gray as a result of tremendous mental shock, often losing their hair due to alopecia areata at the same time. Scientists managed to restore the natural color of hair in laboratory conditions. Metody tej nie da się na razie wykorzystać do walki z naturalną siwizną. Badacze z Manchesteru i Lubeki wykorzystali do swojej pracy cząsteczkę podobną do ludzkiego hormonu odpowiadającego za stymulację melaniny zwaną K(D)PT. Od sześciu kobiet w wieku od 45 do 65 For years, the hair follicles were collected and then placed in the laboratory, where identical conditions were recreated, to the hair of people suffering from severe physical or mental stress and alopecia areata. Turned out, that after the K molecule therapy was performed(D)PT, the amount of dye produced by the bellows has increased significantly. Is it possible to speak of a spectacular success?? It is probably too early for that. It is not known whether the same effect can be obtained under normal conditions outside the laboratory. Research is ongoing.
The age-old mystery of graying has been solved – informs the letter “The FASEB Journal”.
Our hair turns gray, because more and more hydrogen peroxide is formed in the hair follicles over time, that is hydrogen peroxide. Under the influence of this compound, the normal synthesis of the natural dye of our hair is blocked – melaniny.
The discovery was made by an international team, by studying cell cultures of hair follicles. The decrease in the activity of the enzyme that decomposes it is responsible for the accumulation of hydrogen peroxide – katalazy. In addition, the levels of enzymes that protect the hair against graying drop in the hair follicles – MSR A i MSR B.
In addition, high levels of hydrogen peroxide combined with low levels of MSR A and MSR B interfere with the formation of tyrosinase, the enzyme responsible for the production of the dye – melaniny – in the bellows. Perhaps similar changes in the skin lead to the formation of discolored patches on it (bielactwo).
