Hello, Welcome to health care magic You are having hair loss mainly from the vertex and not over the sides and back of scalp. This is a patterned hair fall seen in Male pattern baldness. There are US FDA approved treatments for it like topical minoxidil 5 % solution and Finasteride tablets. Stem cell therapy is basically injecting over the scalp small amount of medicines using a technique called mesotherapy. These medicines contain growth factors which will stimulate hair growth. Personally I feel that it is an adjuvant treatment which can be given along with the above treatment mentioned for added benefit. However it is costly and cost depends from clinic to clinic. Side effects include local injection site pain, head ache and very rarely infection or allergic rash. Why don t you start with medications first rather than going straight away for stem cell therapy?Consult a dermatologist for assessment and initiation of treatment. Vitamin supplements like Biotin and calcium pantothenate along with minerals daily for 3 months will also help. One thing you should realize is this hair loss is in your genes. Whatever treatment you will be on will halt the process. Once treatment is stopped genes will take over. So we need to maintain the treatment on a long term. Hope this helped
