Synopsis

Source of validity: Traditional
Rating (out of 5): 2

Black seed (Nigella sativa) has a long history of use in traditional medicine, including for hair health and hair loss. In various cultures, black seed oil has been applied topically or ingested with the belief that it can strengthen hair, promote growth, and reduce hair loss or thinning. These traditional uses are primarily based on historical texts and anecdotal reports rather than modern scientific validation.

Scientific studies specifically investigating black seed for hair loss or thinning are limited. Preliminary in vitro or animal research suggests that thymoquinone, the main active compound in black seed, may possess anti-inflammatory and antioxidant properties, which could, in theory, benefit scalp health. A few small, low-quality clinical studies and case reports have explored topical black seed oil in combination with other herbal ingredients, noting some improvement in hair density or reduction in hair fall. However, these studies often lack rigorous controls and are not sufficient to conclusively validate black seed’s effectiveness for hair loss.

In summary, the use of black seed for supporting or treating hair loss is primarily rooted in traditional practices. Current scientific evidence is limited and insufficient to fully support its efficacy for this purpose.
