1. You will need to visit a dermatologist and get yourself diagnosed because there are multiple reasons for hair fall. There is no blanket treatment for hair fall that you have described. A thorough examination of the scalp is needed. 2. And to complete the above treatment (and for sustainable long lasting results) you will need to modify your lifestyle. I see that you are an investment banker? Which means that your work hours and eating habits must be chaotic? If no, good, but if yes, then only treatment will never help. Plus, do you get the time to exercise? Find some time. You should ideally clock 150 min of physical activity per week to maintain your health. Your hair is a indicator of your over all health. Bad hair = bad health. So start modifying your lifestyle and visit a dermatologist. You should benefit. There is no quick fix solution for hair fall. And remember that results take a while to show... So be a little patient.
