Synopsis

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

Sea Buckthorn (Hippophae rhamnoides) has been used traditionally in several cultures, particularly in Asia and Eastern Europe, for promoting hair health and addressing issues like hair loss or thinning. Historical and folk medicine texts describe the use of Sea Buckthorn oil, extracted from the fruit or seeds, as a topical remedy to nourish the scalp, promote hair growth, and prevent dryness or brittleness. The traditional rationale rests on its rich content of vitamins (notably vitamin E), essential fatty acids (including omega-3, -6, -7, and -9), and antioxidants, which are believed to support scalp and hair health. However, while these traditional uses are well documented, scientific evidence directly supporting Sea Buckthorn's efficacy for treating hair loss or thinning in humans is limited. A few laboratory and animal studies suggest that the oil's nutrient profile could aid skin barrier function and reduce inflammation, potentially benefiting scalp health indirectly. Yet, robust clinical trials or direct investigations relating to hair regrowth or prevention of hair loss in humans are lacking as of 2024. Therefore, the use of Sea Buckthorn for this purpose is mainly justified by traditional practice and anecdotal reports rather than by rigorous scientific validation.
