There are a number of reasons behind hairloss (in my case it is stress related/hormonal)... But, the first thing to do is see a specialist and have a full blood work done to determine if it is anything medical and if it is treatable.

In the event that it continues, I would suggest scarves or a wig as an option until you can get things under control. I know they have helped a lot when I have had these issues. And will help you regain a sense of normalcy.

If you still find that you are feeling really depressed, it might help to talk with a therapist about your hairloss and any other health issues. You'll feel better and that's what's most important.

Good luck and try to hang in there.
