Hair structure and biological life began to study relatively recently. Before all that knew about them - is that the hair is needed for thermoregulation of the skin that protects from ultraviolet radiation, at a different race - a different type of hair, but also revealed their life cycle. The rest of the hair was not so interesting to scientists, until such time as found in the hair follicle stem cells.
A year ago, an interesting study was conducted. Originally his goal was how to form certain types of rare tumors, but the study found out by chance one of the most important people for answers to the question: "Why do we and the Gmina Łyse Sede?".
The study was conducted at Southwestern Medical Center, University of Texas, studying a rare form Genetic disease - "neurofibromatosis type 1", which provokes the growth of tumors of the nervous system.
Studied in detail KROX20 protein, it is directly related to the growth and development of nerve. But then accidentally found out that KROX20 included in those skin cells, which then become the hair shaft. Before transformed into the hair shaft, the cells produce a "stem cell factor" (abbreviated - SCF) - this protein plays a major role in hair pigmentation.
The studies were conducted on laboratory mice, and found the following: If you remove the same "stem cell factor" of the cells that form the hair shaft, the hair turned white mice. And if you remove the hair shaft forming protein KROX20, the hair does not grow, the mouse became bald.
Who all is well with the English and want to read the full study, with all the photos of mice - you here.
Someone now think, say, and that gives me the information. Well, first of all, hair loss the reason is clear - the whole thing in KROX20 protein, and the cause of gray hair - in the absence of protein SCF.
Secondly, knowing the cause, doctors and scientists now know what to work: they must somehow be safely delivered this protein into the hair follicles. As soon come up with a means - Cosmetics will reach a new level.
Thirdly, this information is useful and appropriate than any nonsense about the egg yolk with a head bow or a haircut on the lunar calendar. Lord, 21 in the yard, already so much is known about our body at the molecular level, but still read invented nonsense, which increases site traffic.
Here are just a person sitting, invents horoscopes and hairstyles of the lunar calendar, and get paid for it. And then these lovers of horoscopes something dare talk about a marketing ploy in cosmetics :-)
Fourth, the hair - this is important. In the first place for the nervous system. It has long been found that gray hair (or even worse - the loss) greatly affects the psycho-emotional state of a person.
Someone gets depressed and someone (here I do not believe it!) Exacerbated Rapunzel syndrome. You know about this syndrome? This "fabulous" mental disorder where a person eats her hair, and then in the intestine formed a ball of hair that creates a small-bowel obstruction. A terrible thing, and because of the balding man can bring yourself to this.
By the way, according to statistics very experienced male pattern baldness.
In general, the hair came from scientists, almost every town has trichologists that will diagnose, say what's wrong and how to fix it. In the future, we still have a lot of interesting talk about hair :-)
Put a "thumbs up" if you want more of these interesting materials on the hair, alopecia, and overall self-care!
