Experts say they have discovered what they believe is the main reason for baldness in men, and pointed out that baldness does not mean lack of hair it is a problem in the new hair that grows in the bald area.
And lead to an imbalance in growth that the hair product in that region is too small to see with the naked eye that leads to baldness that region or light hair in it.
He said the research team, the U.S. magazine "clinical examination," The flaw is in the stem cells responsible for new hair growth.
Experts hope the possibility of "cure" baldness in men, the return of those cells to normal.
The researchers hope to reach a production of ointment is placed on the head helps stem cells to develop normal hair.
The team conducted, a University of Pennsylvania, his research on men who were subject to transfers of hair, and compare the hair follicles in bald areas and hair follicles in the normal hair of the head.
Although the bald areas was the same number of stem cells responsible for hair growth, but he was by a number of less mature cells, so-called "precursor cells" Progenitor cell.
This means that the hair follicles in bald areas shrink or disappear completely and the new hair that grows them to be very accurate compared to the normal hair.
The head of the research team, Dr. George Kotzareli "means that there is a problem in stimulating stem cells to turn into precursor cells in the areas of bald scalp."
He added: "The fact that there are a number of normal stem cells in the bald areas gives us hope in the possibility of activating those stem cells."
It was not known yet what is the specific cause of baldness in men, but experts believe that the relationship is a male hormone, testosterone, and that baldness can be inherited in the family.
