Hello and welcome to healthcaremagic I would like to keep a possibility of androgenetic alopecia, in which there is hormone dependent hair thinning and decreased hair density from the vertex and crown of the scalp. In early stages this type of hair loss manifests as widened part width followed by diffuse thinning in the crown and vertex part of the scalp. I would advice that you see a dermatologist for a confirmatory diagnosis and appropriate treatment. While Biotin, Iron supplementation and High protein diet are usually advised for hair fall, for androgenetic alopecia minoxidil and finasteride are specific remedies. regards
