Question: does apple cider vinegar help oily hair?
Answer: “When properly diluted, an apple cider vinegar hair rinse may help balance the pH of the scalp, prevent hair product buildup, and maintain proper oil balance,” says Marnie Nussbaum, MD, a New York-based dermatologist. To try it, says Dr. David, mix three tablespoons of apple cider vinegar to 1 cup of warm water.
