Hi! Welcome to Healthcaremagic. com. I have read your query in detail and do understand your concern. Yes stressful physical and mental conditions may cause severe hairfall , but since your problem is 5 years old I would doubt it being the predominant cause now. Excessive hair fall can be due to , physical or mental stress, anaemia or nutritional deficiency or certain medical conditions like thyroid disorders, low serum ferritin etc. Take a nutritious and protein rich diet(pulses, milk products, eggs). Use of hair supplements containing biotin will be of help . Avoid routine application of gels or frequent blow drying of your hair. Use a sulfate free shampoo for your hair twice a week. A hair growth lotion or serum can be prescribed to you depending on the cause and severity of your hair fall. Minoxidil 2% lotion can be applied over the affected area twice daily. Hope this helps! Good luck!
