This prospective randomized comparative trial evaluated whether concentrated growth factor (CGF) injections improve outcomes when combined with follicular unit extraction (FUE) in 26 male patients with androgenetic alopecia. Participants received FUE alone or FUE with CGF. At nine months, the CGF group had significantly higher hair density and a greater increase in terminal hair proportion than the FUE-only group (p < 0.05). The abstract also reports favorable safety and high patient satisfaction, but provides no numerical effect estimates.
Key findings
- At nine months, hair density was significantly higher with CGF-assisted FUE than with FUE alone (p < 0.05).
- The increase in terminal hair proportion was significantly greater with CGF-assisted FUE than with FUE alone (p < 0.05).
- The authors reported favorable safety and high patient satisfaction with CGF-assisted FUE.
Why it matters
The findings suggest that adding CGF injections to FUE may improve hair-density and terminal-hair outcomes in men with androgenetic alopecia. These outcomes are relevant to assessing procedural benefit, although the abstract does not quantify the size of the differences or establish how durable they are beyond the reported assessment.
What to keep in mind
The trial included 26 male patients, and outcomes were reported at nine months. The abstract provides no numerical effect estimates.
