Hello and welcome to healthcaremagic. I would keep a possibility of either Telogen effluvium OR Androgenetic alopecia. After a major stressing event like medical/surgical illness (e.g Dengue) OR post-partum OR weight loss (in your case), scalp hair is prematurely pushed into resting phase (Telogen) from the growth phase (Anaphase). This phase usually starts in the third or fourth month after a major stressor and ends by six months if the stressor is removed. There are certain well known causes of Telogen effluvium: --Deficient Iron Stores --Hypothyroidism or hyperthyroidism --Post partum(after delivery) --Post Surgical or following a Medical illness (typhoid, malaria, dengue etc) --Weight loss/ Dieting etc Androgenetic alopecia can be difficult to distinguish from Telogen Effluvium in females, specially early in the course. Later on, Androgenetic alopecia presents as widened part-width and decreased hair density from the vertex and crown of the scalp. I would advice that you get a few lab test done e.g Complete Hemogram, Serum Ferritin levels, Thyroid function tests. In my practice I usually ask my patients of Chronic Telogen Effluvium to take an oral Iron Supplement along with a Biotin supplement for 4-6 months together. 2% minoxidil solution can be applied at the scalp skin twice daily with a dropper (1ml twice daily). Minoxidil is a hair growth promoter and helps in rapid transition of hair follicle from resting phase to growth phase(Anagen). Hope this answers your query. regards
