Some research shows that black seed oil could be beneficial for skin conditions, such as acne.
This may be due to the antimicrobial and anti-inflammatory properties associated with black seed oil (3).
Similarly, one study in 60 people had participants apply a topical gel made with black seed oil to the skin twice daily for 60 days.
Those who did this treatment had a 78% reduction in acne severity along with a significant improvement in the number of acne lesions compared with a control group
Thanks to its antimicrobial and antioxidant properties, black seed oil is often added to hair care products, including hair masks and shampoos (
Though many of these products claim to improve the shine, strength, volume, and texture of hair, there is very little research on the benefits of black seed oil for hair health.
Similarly, a study in 90 people showed that a hair oil containing a blend of black seed oil and other herbal ingredients significantly reduced hair loss after 90 days (13).
It’s important to note that these study treatments combined black seed oil with other ingredients, so we can’t know for sure whether black seed oil was causing the improvements in these cases.
Therefore, despite these promising results, more large, high quality studies are necessary to investigate how black seed oil could affect hair health when used on its own
