Q: I have heard using vinegar on my scalp could help. Now I rub vinegar on my head for a few minutes before I shampoo. I have not been troubled since.
A. You are not the first to share the vinegar approach to dandruff management. There may even be a scientific explanation.
Dandruff is caused in part by yeast that lives on the skin. Vinegar disrupts the acid-base balance of the skin and makes it inhospitable for these organisms. That may explain why it helps against athlete’s foot, dandruff and even nail fungus.
