There's no fixed pattern.

Hair grows in cycles -- each follicle produces a hair which grows then eventually falls out and eventually the hair follicle produces another hair.

Very often, if you get your hormones back into the normal range for females, when the existing coarse, male-type hairs eventually fall out of their own accord, the follicles will produce new hairs which are somewhat less coarse and possibly less-colored and will grow less quickly.

However, it's not as simple as that. If your skin has been sensitized during fetal life so that it responds readily to testosterone, it may continue to respond to even normal female amounts of testosterone. And also, once coarse, male-type growth is established, it doesn't always disappear. For example, males who are castrated as mature adults still grow a beard -- the growth is just slower than it was before. And those are people with almost NO testosterone in their bodies.

So while the hirsutism will almost certainly be reduced, the effects may not be quite what you might have imagined.
