Apple cider vinegar (ACV) is widely used as a natural remedy for scalp and skin issues, including dandruff. However, there is “no scientific evidence proving ACV treats dandruff,” even though many people claim it helps based on personal experience.
Some reported benefits include balancing the scalp’s pH, helping remove dead skin cells, and possibly reducing fungal growth that can cause irritation. Still, these effects are based on anecdotal evidence, meaning they are not scientifically confirmed and should be approached carefully.
A 2022 review suggested ACV may be more helpful for dry scalp, which is often mistaken for dandruff because of similar symptoms. While ACV does show some antimicrobial and antifungal properties, research also shows it “does not work on all microorganisms” and its effectiveness depends on factors like dilution and the specific organism. This highlights the need for more studies before considering ACV a reliable treatment.
Despite limited evidence, some people use diluted ACV at home by mixing it with water, applying it to the scalp, leaving it for about 15 minutes, and rinsing thoroughly. Safe use is important—always dilute it, avoid contact with eyes, and stop use if irritation occurs.
Although natural remedies can be appealing, it’s best to understand their limits. Consulting a healthcare professional is recommended, especially for people with sensitive skin or existing conditions.
