Foods that can contribute to hair loss often include processed items, sugary snacks, greasy fast foods, high-mercury fish, excessive dairy, and alcohol, as they can cause inflammation, disrupt hormones (like increasing DHT), block follicles, or lead to nutrient imbalances, while over-supplementation of Vitamin A, E, or Selenium can also be harmful.
