Can breast augmentation surgery cause hair loss?

There is a condition called telogen effluvium, which is hair loss after a stressful event such as surgery.  It can also be caused by medication or other psychological or physical stress,  It reportedly occurs a few months after the procedure and generally does not affect the entire scalp.   It is a rare occurrence and typically improves over time.  Many years ago I had a breast reduction patient who was diagnosed with this condition when she had hair loss several months after her surgery.  She has done well and her scalp has recovered for the most part, although her hair is still thin.  You are two years out from your procedure and might want to consult with a dermatologist or other specialist to rule out other possible causes and possibly have treatment..  

Change of blood flow, and scarring (deep and at the skin level) can cause hair follicles to shut down restricting new hair growth. The current hair may go in the dormant phase (telogen) and fall out (telogen effluvium). Areas involved with scarring may result in areas of permanent loss of hair.Please read the attached link for more information. 

Breast augmentation surgery would not cause you to have hair loss. You should address this with your primary health care physician.
