"Olive oil helps improve hair": experts debate the effects of an ancient remedy

Experts are debating the social-media comeback of hair oiling and what the science says about olive oil for hair care.

Studies and expert opinions suggest olive oil may reduce protein loss, improve hydration, and help protect hair from damage.

Some sources also point to possible antifungal effects, but the real benefits depend on hair type and use case.

The topic matters because it separates a viral beauty trend from evidence-based hair health claims.
