Thanks for consulting. I have carefully worked through your case, and I can realize your health worries. Being your physician, I assure you not to worry as I will take care all of your medical concerns. the medication he prescribes are vitamin tablets that helps regrowth or hair or reduce hair fall. it will not work if taken for just once. you need to take it for long time to see its results. the hair fall will mostly be due to use of chemical cosmetics and too much of pressure to hair while combing or styling with hair, or may be due to vitamin deficiency. so you can go forward with the treatment prescribed by your doctor. Hope it helps. If you need further, detailed and quick assistance related to any health issues in future, feel free to ask me a question directly from my profile. Have a wonderful time ahead. Best Regards! Dr. Arunmozhi varman
