I am in US for last 10 yrs. My hair is thinning along the center partition on top of my head. This happened since I have been living in US. When I went to my country for an year two years back, I felt my hair regrowing and getting better. Please suggest the cause and treatment for this. also I feel some scalp pain all along the portion where I am experiencing the hair thinning.
Environmental factors can accelerate the hair loss. Your case is rather unusual and interesting. Stress can activate or accelerate hair loss/thinning. Ask yourself if living in America is more stressful. Diet is another important variable that is different in different countries. Lack of certain elements in your diet can cause hair loss, but that would take an extensive analysis to understand what you are eating in and out of the US and how they compare. There are also certain food ingredients in certain geographic areas that may help hair growth (maybe you have some cure to hair loss from your native country in the foods you eat there). Look back and see what you have done and eaten during the time you have been away that affected your hair loss and you may reverse-engineer it and come up with a new solution that we can all talk about.
