Greetings.
You could be having telogen effluvium due to the various forms of physical and emotional stress your body has undergone. This weakens the hair at the hair root and it is shed ; however, there will be regrowth of hair so don't worry. A visit to the dermatologist is advisable and make sure you have a good balanced diet.
