Some men have accepted their baldness as a characteristic style and bare head are satisfied. But for those who are worried about the head of the head, scientists may have a breakthrough solution. According to the latest research, the secrets of human hair growth could be in the molecular switch, the mechanism that the hair growth could restore. Scientists have already found the switch, they just can’t reliably activate it.
“These examples tell us that the molecular plan for the growth of very long hair has always existed, although often in a sleeping state. This discovery indicates that Instead of looking for a new biological mechanism, we can use the sleeping genetic potential for long hair waiting to start, ” explains Professor Sung-Jan Lin from Singapore University.
Scientists say that Long hair probably appeared when people first appeared in Africa about 300,000 years ago when their long and dense head vegetation protected from intense sun.
The co -author of the study, Professor Nina Jablonská of Penn State University, explains in more detail the evolutionary origin of human hair: “People have grown extremely long hair on their heads from time to time. Likewise, the properties of hair – their length, cut, color and loss – play an essential role in social communication. The longer hair growth not only limited the effects of heat, but also kept vital water and electrolytes in the head, which could mean the difference between life and death in the extreme conditions of Africa in our ancestors. ”
Scientists believe that if they manage to find out how the molecular switch for the growth of dense and long hair works, it could lead to a treatment that would prevent hair loss or even reversed and renewed growth.
“When we understand how very long hair grows from hair follicles on the head, we naturally get new molecular targets for more effective hair loss therapies,” The authors deliver. If a molecular switch actually manages to activate, it could provide a more effective method of combating male baldness that affects four to five men out of ten.
