How to prevent hair loss is going on for an year now. I also experience pain in frontal head from where I am losing hair while massaging my scalp. What should I do?

Seek Qualified Help. Genetic or Medical issue? Before you go shopping for hair growth products, treatments & services, the first most important thing to do is find a doctor qualified to diagnose, measure, treat & track your hair loss/hair growth over time. Find an ABHRS-certified Hair Restoration M.D. to evaluate your situation. You need a specialist on your side & this may NOT necessarily be your local dermatologist.
