We are all different in a myriad of ways. From our height to the color of our eyes, there are things that define who we are each of us that often cannot be changed. Sure, you can wear thick-bottomed shoes to gain an inch of height or wear colored contact lenses, but baldness is something most people only accept as part of what it is. Hair loss is often hereditary, meaning it is passed down through generations, but it is not the only cause, and researchers have been working to find out how we might be able to slow the progress of hair loss or even prevent it with certain interventions.
Now, a new study by the same team of Harvard scientists that found clear links between stress hormones and premature gray hair has returned with another paper. This examines the links between stress and hair loss, and the results could be a big step toward developing treatments that prevent hair loss in certain people.

Stress can have an incredible impact on our body and most of the time it is negative. Stress can affect sleep patterns, cognition, and physical health in several ways. As for our hair, stress hormones can cause hair follicles to start growing gray hair sooner than they could, and based on this new round of research, they can also cause the hair follicles close.
The study, which used mice as a model for hair growth, loss and regeneration, found that hair follicle stem cells are quite sensitive. When thrown out suddenly, the phases of growth and rest between which the follicles usually circulate are deformed. The cells end up spending more time dormant than they should be and, as expected, hair loss and lack of regrowth continue.
As animals age, including mice and humans, hair follicles tend to spend more and more time in the resting phase, but the researchers were able to reverse it. They removed the stress hormones that affected the hair follicles and the hair began to grow faster, even in larger mice. Part of hair loss is related to age and genetics, but stress (or lack of it) can change things for better or worse.
“Therefore, even the initial level of stress hormone that normally circulates in the body is an important regulator of the resting phase,” said Ya-Chieh Hsu, lead author of the study published in Nature, he said in a statement. “Stress essentially only elevates this existing“ adrenal gland – hair follicle ”axis, making it even more difficult for hair follicle stem cells to enter the growth phase to regenerate new follicles. hairy licles “.
It may be impossible to eliminate stress from your life, but the findings of this new round of researchers could ultimately lead to treatments that increase hair growth or stop hair loss.
