Suggest Treatments For Hair Loss

Hi!! My name is Francis and i am from Chennai. I have been losing hair for almost five years now and i have tried lots of things to improve the condition. but nothing has really worked for me as yet. I thought there must be some problem with me internal organs and i did a thyroid and anemia test. Even then there was nothing abnormal. I suspect that my hormone would be a culprit in this. Can you give me some clarity on this problem of mine?? Thanks
