Hello. my hair is falling out a lot. i put hijab but i didn't have this problem before what can i do? please help what can i take?

See dr.: Sometimes with stress or illness, the hair enters the last part of its cycle at the same time and appears to be all falling out. Hair loss is normal, but not all at once. Severe illness, scalp infections and skin conditions, thyroid conditions among other illnesses can cause female hair loss. The hijab shouldn't cause it unless it pulls on the hair and you lose it from traction as a tight ponytail
