Alopecia is a common autoimmune condition that causes hair loss. While the condition is not directly caused by diet, nutrient deficiencies, supplement use, and other dietary factors can affect hair loss. For example, vitamin D and zinc deficiencies are linked to both the incidence and severity of alopecia areata (AA). Certain diets, such as the Mediterranean diet, have been found to promote hair health and growth in androgenetic alopecia. Additionally, gluten-free diets have been shown to stimulate hair growth in AA patients with celiac disease. While diet may not be the sole cause of alopecia, nutritional factors can influence the condition and should be considered in treatment plans.

What You'll Learn
Nutrient deficiencies and supplement use
The gut microbiome is also influenced by diet, and there is a known link between the microbiome and alopecia. Incorporating fermented foods like yogurt, kimchi, kombucha, or sauerkraut into your diet, or taking a daily probiotic, may help.
In addition, extreme diet restrictions have been found to trigger telogen effluvium (TE), a type of stress-induced, transient alopecia. This highlights the potential role of diet in treating alopecia.
It is important to note that while diet can play a role in hair loss, there are also other factors to consider, such as medical conditions, hormonal dysregulation, and infection.

Mediterranean diet and anti-inflammatory foods
Alopecia areata is an autoimmune disease that causes hair to fall out in small, round patches. It affects nearly 7 million people in the United States, including approximately 20% of cases involving children. While alopecia areata does not typically affect physical health, it can have psychosocial and psychological impacts.
Although there is limited research on the link between alopecia and diet, diet is known to affect a wide range of health disorders. The Mediterranean diet, in particular, has been shown to be anti-inflammatory due to its focus on whole foods and omega-3 fatty acids, as well as the elimination of processed oils and highly processed foods. This diet includes an abundance of fresh fruits and vegetables, healthy fats, whole grains, lean protein sources, herbs, spices, and limited meat and dairy consumption.
The Mediterranean diet has been recognized as one of the healthiest diets in the world and is packed with some of the best anti-inflammatory foods. Research has identified this diet as the closest thing to an "anti-inflammatory diet," as it emphasizes including plenty of fruits, vegetables, whole grains, lean protein, herbs, spices, and healthy fats every day.
Following an anti-inflammatory diet such as the Mediterranean diet can help combat inflammation and ward off chronic diseases associated with it. People who consume a diet rich in fruits, vegetables, and fiber generally have lower incidences of inflammatory diseases. Additionally, research from 2020 shows that consuming specific foods that are part of the Mediterranean diet, such as olive oil, can reduce inflammatory biomarkers.
In terms of alopecia, the Mediterranean diet may be a potential adjunct therapeutic for the treatment of nonscarring alopecias. The diet contains anti-inflammatory nutrients that may promote hair health and growth in androgenetic alopecia (AGA). Additionally, a gluten-free diet has been shown to stimulate hair growth in alopecia areata patients with celiac disease.
Overall, while more research is needed to fully understand the link between alopecia and diet, the Mediterranean diet may be beneficial for individuals experiencing hair loss due to its anti-inflammatory properties and potential positive impact on hair health and growth.

Gluten-free diet and alopecia areata
Alopecia areata is an autoimmune disease that causes hair to fall out in small, round, smooth bald patches on the scalp and can eventually lead to complete hair loss on the scalp or the entire body. It is the second most common form of hair loss, with nearly 7 million people in the United States suffering from it.
There is a relatively high rate of celiac disease in patients with alopecia areata, which has led healthcare providers to recommend celiac disease blood tests for those with alopecia. Celiac disease is a condition where gluten, a group of proteins found in wheat, rye, and barley, triggers intestinal damage. It is associated with hair loss, and following a gluten-free diet can help restore hair lost while undiagnosed or while still consuming gluten.
A 2020 review of 24 articles found that a gluten-free diet high in raw vegetables, soy, and protein led to symptom improvements in the majority of patients with alopecia areata. However, it is important to note that the patients included in this review also had celiac disease, and a separate study found that a gluten-free diet had no effect on hair growth in alopecia areata patients with celiac disease. Despite this, research suggests that a gluten-free diet may also benefit people with alopecia areata who do not have celiac disease.
In addition to a gluten-free diet, other dietary changes can help manage and treat alopecia areata. A diet rich in vegetables, fruits, healthy fats, and whole grains may improve symptoms and provide additional protective benefits. Specifically, the Mediterranean diet, which includes fruits, vegetables, and protein, may help strengthen hair and minimize loss. It is important to note that fad diets can often lead to hair loss, so it is recommended to eat a well-balanced diet.

Micronutrients, vitamins and minerals
Micronutrients, vitamins, and minerals are essential for overall health and well-being, and they also play a crucial role in maintaining healthy hair and scalp. While alopecia is primarily an autoimmune disease that causes hair loss, nutritional deficiencies can contribute to hair loss and affect the severity of alopecia.
Vitamin D and zinc are critical micronutrients that have been linked to both the incidence and severity of alopecia areata (AA). Patients with AA often have lower serum vitamin D and zinc levels, and vitamin D deficiency is more prevalent in these patients. Therefore, ensuring adequate intake of vitamin D-rich foods or supplements may help manage this condition. Good sources of vitamin D include cod liver oil, liver, fatty fish, full-fat milk, and yogurt.
Zinc is another essential mineral for immune function, and its insufficiency is linked to AA. Foods such as oysters, beef, pork, chicken, pumpkin seeds, almonds, and fish are rich sources of zinc. However, it is important to note that excessive intake of cereal grains might inhibit zinc absorption.
Vitamin A is also important for immune function and can be obtained from various food sources. These include fish oil, liver, oily fish (such as herring, sardines, salmon, and cod), eggs, chicken, kumara, pumpkin, carrots, mangos, apricots, broccoli, full-fat yogurt, and milk.
In addition to these specific vitamins and minerals, a well-balanced diet that includes a variety of fresh fruits, vegetables, and protein sources may help strengthen hair and minimize hair loss. The Mediterranean diet, rich in raw vegetables, fresh herbs, and isoflavone-rich soy, is one example of a diet that may promote hair health and growth.
While diet alone may not be the sole cause or solution for alopecia, nutritional deficiencies can contribute to hair loss and affect the severity of the condition. Therefore, ensuring a well-balanced diet rich in essential vitamins, minerals, and micronutrients may help support overall health and potentially mitigate hair loss associated with alopecia.

Fad diets and hair loss
While diet alone may not be a cure for alopecia, certain diets may help manage the condition. Alopecia areata (AA) is an autoimmune condition that causes hair loss. People with AA tend to have lower serum vitamin D, zinc, and folate levels. A diet that includes foods rich in these micronutrients may help treat the condition. For example, the Mediterranean diet, which includes fruits, vegetables, and protein, may help strengthen hair and minimise hair loss.
Additionally, a gluten-free diet has been shown to stimulate hair growth in AA patients with celiac disease. The anti-inflammatory properties of the Mediterranean diet may also promote hair health and growth in androgenetic alopecia (AGA).
Some people with alopecia have reported that their appetite and cooking routines were affected when they felt low or less confident because of their condition. It is important to note that a well-balanced diet is crucial for overall health and can also impact hair health.
While there is a link between diet and hair loss, it is important to consult a medical professional or a registered dietitian before making any significant changes to your diet or taking any supplements.
