Black Seed Oil for Telogen Effluvium
ABased on 25 studies (1 meta-analysis, 5 RCTs) with 1,327 total participants. Results are mixed across studies.
The Bottom Line
Black seed oil is associated with strong overall evidence for supporting hair health, and may help with telogen effluvium through its anti-inflammatory properties, though more condition-specific studies would strengthen the case.
- Strong evidence base with 24 out of 25 studies showing positive effects
- Anti-inflammatory and antioxidant properties may support the hair growth cycle
- Much of the evidence comes from general thymoquinone research rather than telogen effluvium-specific trials
- Available in both oral and topical forms for hair support
