Pcos maybe ?

I have had pcos since the age of 14 recently after my second child I started losing globs of hair I mean large chunks to where I went completely bald on top my head my head has been itchy for years just recently decided to shave my head I’ve been noticing my head is still itching so decided to take a picture of my whole head the back doesn’t itch as bad as the top an I didn’t scratch it prior to this picture was wondering if this is a side effect of pcos or could be something else ... there are so many side effects of pcos do I didn’t know if this was a thing or not
