Nigella Sativa (Black Seed Oil)

Oil derived from the seeds of Nigella sativa, also called kalonji or black cumin. It has a long history in traditional medicine but also a real modern research base. Its primary active compound is thymoquinone.

Thymoquinone has documented anti-inflammatory and antioxidant activity. In a hair-loss context, the mechanism is indirect but real: scalp inflammation is a known contributor to follicle miniaturization and shedding (particularly in conditions like telogen effluvium and some forms of androgenetic alopecia). Reducing that inflammation is the actual pathway to supporting follicle health, not a direct growth-stimulant mechanism like caffeine or minoxidil.

Most black seed oil hair research is small-scale (dozens to low hundreds of participants) or preclinical (animal and cell studies), not large randomized controlled trials. That's why we describe it as reducing hair fall and supporting follicle health, rather than claiming it regrows hair.
