Conclusión
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
