It is correct to say that people are more likely to lose their hair when they are under stress. The loss of 100 hairs a day or less is a normal part of the hair cycle. High mental stress, long-term tension or depression can easily cause local microcirculation disorders in the head, while the body’s endocrine environment will also change, resulting in long-term pathological hair loss and hair loss. Under the effect of mental stress, the human body’s hair standing muscle contracts, the hair stands upright, while contracting the capillaries that carry nutrients for the hair follicles, resulting in local blood circulation disorders, resulting in hair ecological changes and malnutrition. Mental stress can also cause excessive sweating and sebaceous secretion, which can easily breed bacteria and reduce the environmental quality of the scalp, thus making it easier to lose hair. In addition, baldness, which is often encountered in clinical practice, is also associated with mental factors. It is a kind of localized patchy hair loss with sudden onset, which may be related to the temporary inhibition of hair growth caused by mental factors, endocrine disorders, immune dysfunction, and other factors such as infections or other visceral disorders. There are various reasons for hair loss, and to prevent abnormal hair loss, we should specifically understand the source of stress, learn to release stress, and maintain adequate sleep and a happy mood, rest properly, strengthen physical exercise, and go to the hospital to seek scientific treatment to relieve symptoms if necessary.
