minoxidil shed

[worried90]

I have been using rogaine 5% for about 9 months now and have experienced pretty good growth in the crown area and slow growth in the front. Until now. I realise I have been shedding more hair than normal. Usually when I apply rogaine, I will see maybe 3-4 strands of hair on my fingers. But recently that number has increased to 10+. And I notice more hair dropping than usual throughout the day. Is this normal? Has anyone else experienced this?

Thanks!
