ミノキシジル : 休止期脱毛症
A エビデンス 複数の大規模臨床試験が一貫して有意な効果を示しています。合計20,927名の参加者を対象とした52件の研究(メタアナリシス1件、RCT 1件を含む)に基づく。52件中39件の研究で肯定的な効果が示されている。
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
