Telogen effluvium is a common form of diffuse hair loss when the body goes through a traumatic event such as severe infection, virus, major surgery, child birth or nutrient deficiency.
The shedding can begin 3 to 6 months after the stressful event. It is possible to lose handfuls of hair or just experience increased loss.
The hairs that were the anagen (growing) or catagen (transitional) can move into the telogen (resting) phase and then fall.
Most will recover from this but for some females this can persist for many years. It is important therefore to understand and identify the triggers.
