Synopsis

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

Sea Buckthorn Oil has a long history of use in traditional medicine, particularly in Eurasia, for supporting skin, hair, and nail health. Its use for nails is mainly based on its rich content of fatty acids (including omega-3, -6, -7, and -9), vitamins (notably vitamin E), and antioxidants, which are believed to nourish and strengthen keratin-based tissues such as nails. There are folk practices that include topical application or oral ingestion of sea buckthorn oil to help brittle or weak nails, with the rationale that improved nutrient supply may enhance nail resilience and appearance.

However, direct scientific studies examining the effects of Sea Buckthorn Oil specifically on nail health are scarce. Most research focuses on its benefits for skin and mucous membrane integrity, wound healing, and anti-inflammatory properties. A few small studies and anecdotal reports suggest potential improvements in nail strength and reduction in brittleness, likely due to the oil’s nutritional profile. But rigorous clinical trials directly linking Sea Buckthorn Oil to nail health outcomes are lacking. Thus, the evidence supporting its use for nails is primarily traditional, with only low-level support from indirect scientific findings.
