###Human: Does shampooing daily and dandruff cause hair fall? ###Assistant: Hello. As you have told, you have a dandruff problem and oily scalp that is seborrheic dermatitis which can be mild or can be severe. And yes hair can fall due to dandruff problem. I will suggest a few things for this. For proper hair growth ensure proper diet with Vitamins and Minerals. For dandruff problem, use Zinc Pyrithione based shampoos. Take Biotin supplements that are very important for hair growth. Apply Zinc Pyrithione shampoo or Selsun blue shampoo three times per week. Take Biotin tablet supplements. Apply shampoo for 5 minutes and then wash it.
