Why Stress Can Lose Your Hair – Scientists have discovered how stress can stop the movement of hair follicles in a discovery that could pave the way for hair loss treatment.
- Researchers have studied the role of the stress hormone corticosteroid in hair
- Experiments on mice have shown that it inhibits the production of the chemical GAS6
- This can cause hair follicles to last longer and lead to hair loss
Stress can lead to hair loss and shaving, a new study suggests.
Researchers at Harvard University have shown that in rats that are released during stress, the hormone corticosteroid (GAS6) is released.
GAS6 promotes the growth of hair cells and prevents high levels of corticosteroids in a person or animal under stress.
The findings have not yet been applied to humans, but researchers believe the method is similar.
Experts hope that by understanding the root cause of hair loss, they will be able to develop treatments for stress baldness.

What are the causes of hair loss?
It is quite common for people to lose 50 to 100 hairs a day when it is self-filling and on average.
However, it can be even more tragic and a sign of something serious if people start losing all their hair or a lot of volume.
Hair loss is a common occurrence as people get older. At least half of men over the age of 50 lose some of their hair in old age, according to the British Association of Dermatologists.
Women may also lose their hair as they grow older.
Other causes of hair loss include increased stress, cancer treatment such as chemotherapy or radiotherapy, weight loss or iron deficiency.
Most hair loss is temporary, but is expected to grow again.
Certain medical conditions that cause hair loss include alopecia, immune system disorders; Immobile or excessive activity thyroid; Skin condition lichen planus or Hodgkin’s lymphoma, a type of cancer.
People should see a doctor if their hair starts to fall out, falls out suddenly, sneezes or burns, and is experiencing severe hair loss.
For his part, Ya-Cheh Hussein, a professor of stem cell and regenerative biology at Harvard University, said:
Throughout a person’s life, hair follicles go through three stages – anesthesia, growth stage; ‘Catagen’, the degree of decay; And ‘telogen’, vacation time.
During anesthesia, a follicle constantly pushes the hair shaft. In catagen the growth stops and the lower part is reduced, but the hair stays in place.
At the telogen level, however, the hair follicle cell is not active, and as a result, the hair may soon fall out.
The US-based team studied the role of stress hormones in mice by removing the adrenal glands that produce the chemical.
The modified mice were unable to produce corticosteroids in a stress-free environment.
Evidence suggests that the hair follicles of these mice were in the telogen for only 20 days, three times less than those in the untreated rat corticosteroid.
The follicles have been involved in hair growth three times, the researchers said.
Researchers then found that the mice were successfully resuscitated by injection of GAS6.
Returning GAS6 expression to stress – can overcome hair follicle stem cells – and encourage growth regeneration, ”explains Professor Hussein.
Professor Ruy Yi, a dermatologist at Northwestern University in Chicago who did not participate in the study, said:
‘The authors may have developed an previously unknown mechanism that directly stimulates hair follicle cell proliferation (HFSC) by promoting cell division.
“Stress hormones inhibit hair follicle cell growth by inhibiting growth in mice,” said Ya-Chih Hussein, a professor of stem cell and regenerative biology at Harvard University.
‘Modern life is bound to suffer. But maybe, one day, it will be possible to fight the negative effects of chronic stress on our hair – by adding some GAS6. ‘
Nowadays, transplanting hair follicles from one part of the body to another is the only option for male pattern baldness.
The study was published in the journal Nature.
Scientists say they have found a cure for BALDNESS from medicinal trees
Researchers in Thailand say that they have found a substance in mango trees that can cure baldness.
A small study of 50 people suffering from androgenic alopecia – the most common type of baldness – stops the hair loss and promotes hair growth.
Avicequinon-C contains a key chemical called avichenia marine.
This active ingredient is thought to alter hair follicles by interfering with enzymes that lead to high levels of hormones that cause baldness.
The researchers hope that the findings will help people suffering from androgenetic alopecia to change their hair loss.
