Hello. Thanks for writing to us at healthcaremagic Hair can be due to various causes. The common causes in a female being either Telogen effluvium or Female pattern Androgenetic Alopecia. Telogen effluvium in turn can be due to multiple causes; common ones being Deficient Iron stores, Thyroid (hypothyroid or hyperhyroid), Drugs (antiepileptics like valproate), Post-delivery (post-partum hair loss), Post stress (either medical illness like e.g dengue malaria jaundice etc Or Severe Psychological stress), Weight loss etc The identification of underlying cause requires a detailed history, physical examination as lab tests like complete hemogram, thyroid, serum ferritin levels etc. 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. Female Pattern Androgenetic Alopecia (FAGA), which is also a very common cause of hair fall and thinning, but 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. The hair loss in FAGA is gradual over the years and although the scalp remains covered, the hair volume is reduced. Androgenetic alopecia (FAGA) in females is commonly managed with 2% minoxidil solution is a non-specific hair growth promoter can be applied at the scalp skin in this type of hair loss, 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). These are all prescription medicines and therefore I would suggest that you visit a dermatologist in your region for a proper assessment and treatment accordingly. The treatment need to be taken for at least 4-6 months at a stretch. The results are slow, don t expect immediate results. It is advisable to continue treatment for a good 1-2 months to judge whether they are going to be effective Or not. Regards
