Switching to a vegetarian diet can bring many health benefits, but some people experience hair loss after making the change. If you have noticed hair thinning or shedding after going vegetarian, you might be wondering: Will my hair grow back? Let’s explore the reasons behind vegetarian hair loss and what you can do to restore your hair health.
Does a Vegetarian Diet Cause Hair Loss?
A vegetarian diet does not directly cause hair loss. However, it can lead to nutritional deficiencies that may contribute to hair thinning. Here are some possible reasons:
1. Drop in Estrogen Levels
- When you stop eating dairy, your body’s estrogen levels may decrease.
- Dairy products contain hormones from pregnant cows that can stimulate hair growth.
- A lower estrogen level can cause temporary hair shedding, similar to postpartum hair loss.
2. Lack of Healthy Fats
- Healthy fats help produce hormones that support hair growth.
- A low-fat vegetarian diet may reduce natural oil production, leading to weaker hair.
- Adding foods like avocados, nuts, and seeds can help maintain healthy hair.
3. Iodine Deficiency and Thyroid Issues
- Iodine is essential for thyroid function, and an underactive thyroid (hypothyroidism) can lead to hair loss.
- Vegetarians may have lower iodine intake since fish and dairy are major sources.
- Adding seaweed, iodized salt, or iodine supplements can help.
4. Low Zinc Levels
- Zinc supports hair growth and repair.
- Vegetarian sources include pumpkin seeds, cashews, and lentils.
- A zinc deficiency can slow hair regrowth.
How to Prevent Hair Loss on a Vegetarian Diet
If you are experiencing hair loss, making small dietary changes can help. Below is a table with essential nutrients for hair growth and their vegetarian sources:
Nutrient | Role in Hair Growth | Vegetarian Sources |
Protein | Builds strong hair strands | Lentils, chickpeas, tofu, quinoa |
Iron | Prevents hair shedding | Spinach, beans, fortified cereals |
Zinc | Supports hair repair | Pumpkin seeds, cashews, lentils |
Vitamin B12 | Prevents hair thinning | Fortified foods, supplements |
Omega-3 Fatty Acids | Keeps scalp healthy | Flaxseeds, walnuts, chia seeds |
Iodine | Supports thyroid function | Seaweed, iodized salt, potatoes |
Will Vegetarian Hair Loss Grow Back?
Yes! Hair loss due to a vegetarian diet is usually temporary. Once your body adjusts and you meet your nutritional needs, your hair will start to grow back. Here’s what you can do:
1. Increase Healthy Fats
- Eat half an avocado every other day.
- Include walnuts, chia seeds, and flaxseeds in your diet.
- Use olive oil or coconut oil in cooking.
2. Ensure Enough Protein Intake
- Hair is made of keratin, a protein, so eating enough protein is crucial.
- Add tofu, lentils, chickpeas, and nuts to your meals.
3. Maintain Iodine and Zinc Levels
- Use iodized salt in cooking.
- Eat iodine-rich foods like seaweed in moderation.
- Snack on pumpkin seeds and cashews for zinc.
4. Take Supplements If Needed
- Consider a B12 supplement as plant-based foods lack this vitamin.
- Take an iron supplement if you are at risk of anemia.
- Consult a doctor before starting any new supplement.
5. Be Patient
- Hair grows in cycles, so it may take 3-6 months to see visible improvement.
- Focus on a balanced diet and manage stress for better hair health.

4. Do vegetarians go bald more often than meat-eaters?
No. There is no evidence that vegetarians experience more permanent hair loss than non-vegetarians. Nutrient balance is key.
