I just recently switched from Rogaine Minoxidil to Kirkland. about 2 weeks in I noticed lots of hairs on my hand when I applied it to my hair. When I wash my hair I'm seeing lots of hairs now. If I run my hand through my hair a few times hairs are falling out into the sink. These are things I would always do previous and I would never have any hair fall maybe 1 or 2 stray hairs but now I'm seeing 10-20 or more. Is this normal after switching brands or is something else up?
