Apple cider vinegar (ACV) has been used for generations in natural beauty routines, and many people rely on it as a simple at-home remedy for improving hair appearance. Its slightly acidic nature can help refresh the scalp and remove the residue left behind by styling products. Because of this, ACV has become a popular choice for those looking to maintain clean, balanced hair without using heavy treatments.
But the real question many people ask is what happens when ACV is applied to the hair and left overnight. In my experience, the first noticeable effect was how refreshed the scalp felt the next morning. ACV is known to help dissolve buildup from products such as gels, sprays, and conditioners. Letting it sit for a longer period allowed it to work gradually, leaving the scalp feeling cleaner than usual.
Another benefit was the way my hair appeared after rinsing—it looked smoother and slightly shinier, likely because ACV can help flatten the outer layer of the hair strand, making light reflect more evenly. It’s important to remember that ACV should always be diluted with water before use, especially for sensitive skin. Applying it directly to the scalp without dilution may cause irritation for some people.
