Emotional stress, staying up late and constipation can lead to endocrine disorders, affecting the health of hair follicles and scalp oil secretion. Since hair loss and mental factors are greatly related, doctors will use sedative hypnotics and antihistamines sometimes to relieve psychological symptoms of patients, and some have also advocated the taking of vitamin B1, B6 or B12 and other medications that are able to regulate nerve function. Pressure is not the direct cause of hair loss or hair greying, but the inducing factor.
Accumulated pressure will lead to a physical condition and environment that will cause hair loss.
