Why is stress cause of hair fall ?

Hair loss: Stress can affect the body in different ways - hair loss is only one. Many things can cause hair loss in addition to stress - hormonal changes, poor nutrition, chemotherapy.

As Dr. T said,: Changes in your body's chemistry - including hormonal balances - are possible suspects in hair loss and stress can make a wide variety of changes in the chemistry of several body systems. So it may be an indirect path to the hair loss - but it's there. Make sense? Best!
