En conclusion

Topical caffeine shows promising early evidence for supporting hair growth in androgenetic alopecia, but the research base is still small and more large-scale human trials are needed.

  • 8 out of 9 studies report positive effects on hair growth
  • Caffeine may work by counteracting DHT's negative effects on hair follicles
  • One RCT showed improved hair density with a caffeine-containing topical product
  • The total participant pool is very small (62 people), limiting the strength of conclusions
