Hi Nadine
There is a name for it. I have been loosing my hair big time and when I asked the GP she told me that it was common and its name (sorry can't remember its name ).
But in my case it could also be from Anti Depressants or my thyroid problem.

Google your anti depressant and find out if hair loss is one of the reactions you can have from it.

Hope I have helped.
Take care
Chris
