結論
Black seed oil shows strong research support for alopecia areata, with nearly all studies reporting positive effects, though more human clinical trials are needed to confirm its benefits.
- 24 out of 25 studies report positive effects, including 4 randomized controlled trials
- Thymoquinone, the active compound in black seed oil, has anti-inflammatory and immune-modulating properties
- Many studies are preclinical (animal or lab-based), so human evidence is still developing
- One case of contact dermatitis from thymoquinone has been reported — patch testing may be advisable
