I share with you what happened to me and Rogaine.
Long time ago now, 12 years ago, when I was 22 I started to have some hair loss. I thought I try to preempt it.
Got Rogaine. Within 2-3 weeks I started using maybe 1000 hairs a day. I stopped. The hair did not come back. I figured I should go back on Rogaine. I did. Within 6 months I had most of my hair back and some.
Looking back, my advice is unless your hair loss is bad do not try minoxidil or finasteride. Otherwise you've got to give it 5-6 months.
This is a real problem for many like you and me. You do not see the +@#*! drug companies reporting this.
