Yes, stress does cause hair loss.
Telogen effluvium, a stress-related chemical, disturbs the hair growth cycle, causing premature hair loss and driving follicles into the resting phase
Stress-related hair loss, which usually appears by extensive thinning, often occurs 2-3 months after an event, with patchy baldness being less common.
Stress hormones such as cortisol may reduce hair growth, promote shedding, and weaken the immune system, making follicles more open to harm.
