Kết luận

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
