A vegetarian or vegan diet can lead to hair loss, but not simply because of a lack of meat. Instead, it is the vitamin and nutrient deficiencies that may occur with a vegetarian diet that cause hair loss. Hair is primarily made up of protein, and iron plays a role in its growth cycles, so it is important to ensure that a vegetarian diet is well-planned and balanced. Nutritional deficiencies that may occur with a vegetarian diet and can cause hair loss include iron deficiency, vitamin D deficiency, and zinc deficiency. However, hair loss due to dietary changes is not permanent, and hair should grow back once the underlying issue is treated.

What You'll Learn
Nutritional deficiencies
Protein is essential for healthy hair growth as hair is primarily made up of keratin, a type of protein. A reduction in protein intake can cause hair fall. People new to a vegetarian diet may not know how to get enough protein from non-meat sources. However, there are plenty of plant-based sources of protein, including beans, nuts, seeds, legumes, and soybeans.
Iron is another vital mineral for hair health. Iron deficiency, or anaemia, is a well-known cause of hair loss. Meat contains heme iron, which is better absorbed by the body compared to non-heme iron found in plant-based sources. Vegetarians and vegans may be at risk of lower iron levels, and the iron found in plants may be harder for the body to absorb. However, pairing plant-based foods high in iron with foods high in vitamin C can help increase iron absorption. Good vegan sources of iron include blackstrap molasses, tempeh, tofu, beans, and legumes.
Zinc is also necessary for promoting healthy hair and repairing damaged hair. Vegetarians and vegans usually have lower zinc levels than those who eat meat, and some plant-based foods contain phytic acid, an "anti-nutrient" that prevents the absorption of zinc. However, deficiencies are rare, and the body can adapt to lower zinc intakes. To increase zinc intake, include foods such as beans, seeds, nuts, and whole grains in your diet.
Vitamin B12 is another nutrient linked to hair health. Some studies have found an association between hair loss and low levels of vitamin B12, although the results are inconclusive. Vitamin B12 can be found in seaweed, sauerkraut, shiitake mushrooms, and edible algae.
Vitamin D is important as well, and vitamin D2 supplementation may help with hair loss in people with a diagnosed vitamin D deficiency. However, vegan sources of vitamin D are limited to irradiated mushrooms, some non-dairy milk, and fortified vegan cereals.
Overall, a well-planned vegetarian or vegan diet can be nutritionally adequate and prevent hair loss. It is essential to be mindful of potential nutritional deficiencies and ensure a balanced intake of essential vitamins and minerals.

Hair loss treatments
Vegetarian and vegan diets can be beneficial, but they can also cause hair loss. This is because the hair follicle is very sensitive to dietary changes. However, vegetarian and vegan diets do not directly cause hair loss. Instead, they can put you at a higher risk of hair loss if your diet does not include the vitamins, minerals, and nutrients you need for healthy hair growth.
Some of the most common nutritional deficiencies that can lead to hair loss are iron, protein, and zinc deficiencies. Iron is often found in meat, but vegetarians and vegans can get it from nuts, spinach, and whole grains. Protein is also commonly found in meat, but plant-based sources include eggs, legumes, seeds, nuts, soy products, and seitan. Zinc is vital for promoting healthy hair and repairing damaged hair, and it can be found in whole grains, seeds, legumes, and some nuts. However, these plant-based foods also contain phytic acid, an "anti-nutrient" that prevents the absorption of zinc.
If you are experiencing hair loss due to a vegetarian or vegan diet, there are a variety of treatments you can consider. One option is medication such as Finasteride, although it is only recommended for male patients. If medication is ineffective, you may want to consider an FUE hair transplant, a safe and trusted process that gives you choice and flexibility over your hair and hairline.
Another way to treat hair loss is to address any vitamin and nutrient deficiencies. This can be done through supplements or food sources. For example, a vitamin and nutrient supplement designed for vegan hair loss and health can help. Additionally, you can change your diet to include foods rich in zinc, B vitamins, and iron. Vitamin B12, in particular, has been linked to hair loss, and it can be found in foods like seaweed, sauerkraut, shiitake mushrooms, and spirulina.
In addition to supplements and dietary changes, there are other strategies that may encourage hair growth. Low-level laser therapy (LLLT) has been found to help regrow hair in female pattern hair loss or telogen effluvium with no side effects. Some oils have also shown promising initial results for hair loss, although there is limited evidence. Plant-based, stimulating hair care products can also be a natural way to keep hair healthy.

Vegetarian diet and hair regrowth
Vegetarian and vegan diets are often associated with health benefits, but they can also negatively impact hair health. A small study found that non-meat eaters tend to have slightly weaker hair than those who eat meat. However, this finding was not statistically significant, and dietary restrictions are not necessarily the root cause of all hair breakage.
Vegetarian and vegan diets can lead to hair loss, but not directly. The vitamin, mineral, and nutrient deficiencies that may occur in these diets are the primary contributors to hair loss. For example, vitamin B12, vitamin D, selenium, and zinc deficiencies are common in vegetarian and vegan diets. Iron deficiency is also prevalent, as plant-based sources of iron can be harder for the body to absorb. As a result, hair follicles, which require a good blood flow to stay healthy, may not receive the nutrients they need, leading to hair shedding and temporary hair loss.
To prevent hair loss on a vegetarian or vegan diet, it is crucial to ensure adequate nutrient intake. This can be achieved by including nutrient-rich plant-based foods in your diet, such as:
- Spinach, kale, and other leafy greens for iron
- Flax seeds and walnuts for omega-3 fatty acids
- Nutritional yeast or vitamin supplements for vitamin B12
- Egg yolks, cheese, or mushrooms for vitamin D
- Whole grains and legumes for protein
- Seeds and dairy products for zinc
In addition to dietary adjustments, exercises, scalp massages, and treatments like micro-needling can improve blood flow to the scalp, promoting hair growth and thicker hair.
If you are experiencing hair loss due to a vegetarian or vegan diet, it is important to consult a healthcare professional. They can help identify any nutrient deficiencies and recommend dietary adjustments or supplements. In some cases, medication or hair loss treatments may be suggested to stimulate hair regrowth.

Blood circulation and hair health
Blood circulation is critical for overall hair development and health. The blood delivers essential nutrients, oxygen, and hormones to hair follicles, which are essential for hair growth. Hair growth and maintenance require these elements to be continuously supplied to the hair follicles. Poor circulation can lead to weakened hair follicles, abnormal hair growth, and even hair loss.
The hair growth cycle consists of three stages: anagen (growth), catagen (transition), and telogen (resting). During the anagen stage, hair grows from the root and can last for several years. The catagen stage is a brief transition period where the hair follicle shrinks. Lastly, the telogen stage is a resting period where the hair stops growing and eventually sheds. The anagen stage is key for hair growth as the hair follicles actively produce new hair cells. An adequate supply of nutrients and oxygen is necessary to support this process.
There are several ways to improve blood circulation to the scalp. One way is to massage the scalp, which can stimulate blood flow to the area. Scalp massages can be done with gentle pressure using the fingers or with essential oils such as lavender, thyme, rosemary, cedarwood, or peppermint. Another way to improve blood circulation is to exercise, as this naturally increases blood flow to all organs of the body, including the scalp. Additionally, eating a healthy diet rich in vitamins and nutrients can help increase blood circulation to the scalp. Foods such as chicken, beef, fish, mushrooms, brown rice, peanuts, green peas, avocados, and turkey are high in niacin (vitamin B3), which increases blood flow to the scalp. Maintaining a healthy circulation system is crucial for ensuring that the hair follicles receive the necessary elements for healthy hair growth.

Hair shedding and diet
Hair shedding can be distressing, and it is natural to look for reasons why it is happening. A change in diet, such as switching to vegetarianism or veganism, can be one of the reasons for hair loss. However, it is not the lack of meat per se but the potential vitamin and nutrient deficiencies that may occur as a result of a vegetarian or vegan diet that can lead to hair loss.
Nutritional Deficiencies
Vegetarian and vegan diets can be highly beneficial, but they often involve cutting out whole food groups, and it can be challenging to get the right balance of vitamins, minerals, and nutrients. For example, vitamin B12, vitamin D, and selenium are found in animal products, and it can be harder for vegetarians and vegans to get these nutrients. Protein is another essential nutrient for healthy hair growth, and it is commonly found in meat. Vegetarians and vegans may need to find alternative sources of protein, such as legumes, seeds, and nuts. Iron is another critical nutrient, and while it is found in both animal and plant products, the iron in some plant products is harder for the body to absorb.
Telogen Effluvium
Telogen effluvium is a type of hair loss that can occur due to nutritional deficiencies. It is characterised by excessive hair shedding because the body is under stress due to a lack of nutrients. However, it is important to note that not all vegetarians and vegans will experience hair loss, and there are ways to ensure adequate nutrient intake on a plant-based diet.
Preventing Hair Loss
If you are experiencing hair loss due to nutritional deficiencies, it is essential to talk to a healthcare professional who can help identify any deficiencies and advise on dietary adjustments or supplements. In some cases, dietary sources may not be enough to correct the deficiency, and supplements may be necessary. Medication can also be used to stimulate hair growth and restore hair thickness and density. Additionally, maintaining a balanced and diverse diet is key.
