Hi there!
Well, without a detailed clinical evaluation it would be difficult to determine the cause of your symptoms. Alopecia or hair loss could occur secondary to a few causes such as cellulites, fungal infections, hormonal imbalance, hypervitaminosis A, some autoimmune diseases such as lupus, medications side effect, infections, folliculitis, endocrine disturbances, a few metabolic conditions, micronutrient deficiencies, chemo/ radiotherapy etc. I would suggest consulting a dermatologist for an evaluation for the above mentioned causes for an appropriate treatment.
Hope this helps.
Take care!
