Scientists hope that they are very close to finding the treatment of baldness. Researchers believe that they have discovered a method that can remove the problem of baldness and hair again on the head.

Scientists of the New York School of Medicine have activated a path within the brain, named 'Sonic hedgehog'. When the baby is in the womb, this path is very active, so that hair follicles are ready. But as the age increases or the wounds in the skin increase, this path is blocked.

Figures show that one-fourth of the men's hair starts flying the age of 25-reaching. Britain's Prince William's hair began to fly at the age of 22. It is not that this problem is only in men.

According to the American Academy of Dermatology, 40 percent of women reach the age of 40 to see the problem of hair fall. The path which is activated by the Doctor Mayumi Ito-led team also works as a communication mechanism between the cells.

Scientists studied the damaged skin of rats in the lab, in which the main focus was on the cells named 'fibroblast'. This cell is secreted by the name of collagen protein. This protein retains the strength and shape of the hair and skin. The researchers also focused on 'fibroblast' because of this, because there are many biological properties like fixing the wound itself.

According to a study published in 'Nature Communication', within four weeks of establishing communication between brain cells, the hair of rats began to grow again. The roots and structures of hair began to appear again within nine weeks. So far scientists used to believe that due to damaged skin the hair can not grow again. But now this evidence has shown a new direction in this area.

Doctor Ito says, "Now we know that this path is very active in the embryo, while with aging, this process starts slowing down. Our research suggests that 'fibroblast' can be corrected through Sonic hedgehog. The hair can be grown again.''

Your hair falls due to many changes in life. Changing homes, mourning or even during pregnancy, hair starts becoming weak. Apart from this, stress, bad food, chemicals dissolved in water, insecticides present in food, contraceptive pills also have major causes of hair fall.
