The localized pattern of hair fall
mentioned by you is most indicative of alopecia areata
Mirena IUD does not have any relation with this disease.
At times it resolves on its own, but may take months together.
There are a number of treatment options like oral/topical/intralesional steroids
, contact irritants, contact sensitizers etc.
Consult a dermatologist
so that the suitable treatment can be started.
