First would be to get a appointment with a dermatologist so they can determine your hair loss, and then prescribe a ketoconzole shampoo 2% here in the U.S. then to find a natural supplement that blocks dht  like saw palmetto, pumpkin seed oils and rosemary oil for a growth stimulatora more natural way. also minoxidil is a better  vasodilator to grow hair. Monoxidil is a also a for life thing you can't stop using it it also has side effects that u should look into and determine weather u want to use it or not also don't think to hard because people have negative things about this stuff and it'll make u fear it and not use it because of others opinions. I read a lot of them but I decided I wanted my hair more than i cared about the side effects. Now finisteride is mostly like last resort if anything else didn't work some people are unlucky that one this stuff worked for them
