I have thin hair, around. Norwood 2.5-3 with diffuse pattern balding across the top. I started on Finasteride in January and Estradiol and Spiro in close to a month ago now. I've been tracking my results with pictures monthly and at haircuts and I'm seeing some definite regrowth. It seems to be more so in the areas where I lost it more recently coming back faster. I just got it cut super short last week and compared it to my previous cut 3 months ago. I've got a long way to go, but I'm hoping that in the next 3-6 months I will be able to let it grow out. I've also been using minoxidil for years, and I'm taking amino acids, folic acid, biotin, and vitamins, as well as started dermarolling my scalp 6 weeks ago. If you're worried at all about your haiross get on it, it's totally possible to turn it around.
