Rogaine - does it work on font of scalp?

[19Delta]

Hi all,
I'm 34. I've just begun to notice thinning on the front of my scalp near my part line on the front of my scalp. This started a few months ago and has become mildly noticeable in the mirror. My hairline has never really receded (never experienced/noticed hair loss until now). Here's my question: is Rogaine effective for the front of the scalp? Is there any way to reverse what's starting to happen (oral or topical)? I notice more change/thinning each haircut.

Many thanks,
19D
