I myself have reversed some male pattern baldness, so I know it's anecdotal, but it can be reversed somewhat. It's mostly because my testosterone is suppressed by Spironolactone which is an anti-androgen rather than because I have estrogen in my body though.

Finasteride targets that specific hormone though without affecting the rest of your testosterone as much though. If I were to recommend anything to you, finasteride is probably the way to go unless you want to be a girl, in which case I will never stop you. Hims is a good place to go for Finasteride

Estrogen does have milder antiandrogenic effects though. Some trans people can go on only estrogen and keep the testosterone away
