Androgenetic alopecia, commonly known as “baldness”, is an aging-related phenomenon that mostly affects men. This can be a real source of stress for some, who do not hesitate to pay the astronomical amount to repair their hair loss.
Researchers from the University of California at Riverside have discovered a chemical that can “Not only treating baldness, but ultimately speeding up wound healing”as reported by The Independent.
Qixuan Wang, one of the authors of the study published in Biophysical Journalexplained: “In science fiction, when characters heal wounds quickly, the idea is that stem cells make this possible. In real life, our new research gives us a better understanding of stem cell behavior, so we can control it and improve wound healing.
By examining hair follicles, the only human organ capable of constantly and automatically renewing themselves, the scientific team discovered that a type of protein called TGF-beta controls not only how stem cells in the hair follicle divide, but also how some die and cause hair loss. .
The TGF-beta protein “there are two opposing roles, Qixuan Wang explained. It helps to activate some cells in the hair follicle to create new life, but it also helps to start the process of cell death.
However, scientists have discovered that when a hair follicle dies, the reservoir of stem cells remains. “When living stem cells are signaled to regenerate, they divide, make new cells and grow into a new follicle,” added the scientist.
As explained by the team of scientists, it is possible to stimulate hair growth by activating follicular stem cells. More research needs to be done on the subject, however, they point out.
Seemingly harmless, hair loss can lead to real psychological suffering for those who experience it, not to mention possible social and professional consequences. Among all the more or less expensive solutions that exist, there is still no one that can be paid for in France.
