結論

Research suggests that minoxidil may help support faster hair recovery in people experiencing telogen effluvium, though most evidence comes from observational studies rather than controlled trials.

  • 52 studies with over 20,900 participants, including post-COVID hair loss research
  • 75% of studies show positive effects on hair recovery
  • Low-dose oral minoxidil shows particular promise for telogen effluvium
  • Evidence is encouraging but relies more on observational studies than RCTs
