Can Being Vegan Cause Hair Loss?

Being vegan can contribute to hair loss if the diet lacks certain essential nutrients that are important for hair health. Hair loss on a vegan diet can occur due to deficiencies in:

  • Protein: Hair is primarily made of a protein called keratin. Inadequate protein intake can lead to hair thinning and loss. Vegans need to ensure they consume enough protein from sources like legumes, tofu, tempeh, quinoa, nuts, and seeds.
  • Iron: Iron deficiency can lead to hair loss. Non-heme iron found in plant-based foods is less readily absorbed by the body compared to heme iron from animal products. Vegans should include iron-rich foods such as lentils, chickpeas, spinach, fortified cereals, and consume them with vitamin C-rich foods to enhance absorption.
  • Vitamin B12: This vitamin is crucial for the production of red blood cells and DNA synthesis. A deficiency in vitamin B12 can lead to hair loss. Since B12 is primarily found in animal products, vegans should consider fortified foods or supplements.
  • Zinc: Zinc is important for hair tissue growth and repair. Vegan sources of zinc include beans, lentils, chickpeas, seeds, nuts, and whole grains. However, phytates in these foods can inhibit zinc absorption, so adequate intake is crucial.
  • Omega-3 Fatty Acids: Omega-3s support scalp health and hair growth. Plant-based sources include flaxseeds, chia seeds, walnuts, and algae-based supplements.
  • Vitamin D: Low levels of vitamin D have been linked to hair loss. Sun exposure and fortified foods can help maintain adequate vitamin D levels, but supplements may be necessary, especially in areas with limited sunlight.
  • Biotin: Biotin (Vitamin B7) is essential for hair health. While biotin deficiency is rare, it’s important for vegans to include biotin-rich foods such as nuts, seeds, sweet potatoes, and avocados.
  • Other Nutrients: Adequate intake of other vitamins and minerals like vitamin A, vitamin E, and iodine is also important for maintaining healthy hair.

To prevent hair loss while following a vegan diet, it is essential to plan meals carefully to ensure all nutrient needs are met. Consulting with a healthcare provider or a registered dietitian can help create a balanced vegan diet that supports overall health, including hair health.
