Apple cider vinegar (ACV) is a natural remedy for balancing scalp pH, reducing dandruff, and adding shine. After applying diluted ACV overnight, the author noticed softer, shinier hair and a cleaner, less itchy scalp. It reduced frizz and product buildup without irritation.

ACV is effective but must be diluted to avoid dryness or irritation. While it’s a natural and cost-effective option for clarifying and adding shine, it doesn’t provide the deep moisture of oils or conditioners.
