Why Is Increased Hair Loss Listed as a Minoxidil Side Effect?

I looked up Minoxidil on Mayo Clinic’s web site, and it said a side effect was hair loss. Seems a bit contradictory, ay?

The use of minoxidil may promote hair cycling. If it does, the initial stage could be hair loss, but that will go away in 2-3 months and the anagen cycle starts up.
