What are the Causes of Hair Shedding?

It's normal to shed between 50-100 hairs per day. When more than 100 are lost, it may be abnormal. Abnormal or excessive hair shedding is known by the medical term "telogen effluvium."

There are many reasons to have hair shedding.  These include physiological stresses on the body (like having a surgery), thyroid problems, crash diets, low iron levels and certain medications. These can all cause hair shedding.

The following video on hair shedding was prepared by Monica Matys of Sunnybrook Hospital in conjunction with the Sunnybrook Media department. I hope you will find it educational and informative.
