Apple cider vinegar (ACV) is a popular natural remedy for hair, known for balancing scalp pH, reducing dandruff, and adding shine. The author tested diluted ACV overnight and noticed “softer, shinier hair and a cleaner, less itchy scalp.”
ACV reduced frizz and product buildup without irritation. However, “it should be diluted properly to avoid irritation,” and excessive use can cause dryness.
Compared to other treatments, ACV is a “natural, cost-effective option” for clarifying and enhancing shine, though it may not offer the same moisture as oils or conditioners.
