Staying up late is very harmful to the skin. The scalp is even more fragile. Often staying up late will lead to endocrine disorders and a long-term nervous state, which will make the scalp in a sub-healthy state, reduce the vitality of scalp skin cells, and accelerate the speed of scalp aging.
In order to maintain the normal operation of the entire body even when staying up late, the human body secretes androgens to keep the body functioning and the brain excited. When there is too much male hormone secretion, the content of DHT in the human body will increase, and DHT is the culprit of hair loss. It will damage the blood vessels around the hair follicles, resulting in insufficient blood supply to the hair follicles, resulting in hair follicles shrinking and hair falling out.
