Before you start, get a baseline if you can with a HAIRCHECK test (https://baldingblog.com/haircheck-test-how-it-is-done-and-what-its-value/) to see how you are doing over time. If you start off seeing a doctor who can build a Master Plan for you, you will be miles ahead in the years to come. Taking dutasteride to start makes no sense to me if you don’t know where you are starting from and this drug has lots of side effects, including sterility in some men (unable to have children).
