Rogaine Foam- Initial Shed

[wingman22]

I started Rogaine foam about 3 weeks ago and my shedding has increased drastically. The top of my head has gotten very thin and it has destroying my hairline.

I knew I would shed, but not this much, and not so soon.

1) Should I be concerned and stop the treatment??
2) If I continue will my hairline repair itself overtime?
3) Does this shed mean I'm a good responder, and should continue??
