Hair loss is a common condition that usually affects men over 50, but it can also affect younger people and women. While factors like family history, genetics, stress, and medical conditions may be stronger influences, diet is an essential component of hair health. A 2013 study found that smoking, alcohol consumption, increased caffeine intake, and stress were linked to hair loss. Furthermore, rapid weight loss from extreme diets or bariatric surgery can lead to hair loss due to nutrient deficiencies. Specifically, a lack of protein, zinc, calcium, and iron can cause hair thinning and increase the risk of breakage. Certain vitamins and dietary supplements may also contribute to hair loss. To maintain hair health, it is crucial to consume a balanced diet rich in essential nutrients and address any nutritional deficiencies.

What You'll Learn
Nutritional deficiencies
Protein, zinc, and calcium are essential for a healthy scalp and hair. Iron deficiency is also linked to hair loss and poor hair growth. Vegans and vegetarians may need to supplement their plant-based diets to maintain adequate iron levels. Zinc deficiency can be reversed through oral supplementation. Pumpkin seeds, lentils, and chicken are good sources of zinc.
Vitamins are also key building blocks of hair. However, supplements that claim to boost hair growth may contain high amounts of nutrients that may lead to hair loss if consumed in excess.

Extreme diets
Hair loss related to extreme dieting has been documented in research as far back as the 1970s. It is important to note that hair loss can also be caused by the stress of rapid weight loss, rather than nutrient deficiencies. In addition, some supplements taken during extreme diets can cause hair loss, especially if they are consumed in high doses without an existing nutrient deficiency. These include vitamin A supplements, which can overwhelm the liver and lead to high levels of the vitamin in the blood, disrupting hair follicle function.
To prevent hair loss, it is important to avoid extreme diets and instead focus on consuming a balanced diet rich in nutrient-dense foods. A healthy diet is crucial for a healthy scalp, which is more likely to grow healthy hair. Micronutrient supplements may be necessary to correct deficiencies and prevent hair loss, but it is important to consult a healthcare professional before taking any supplements.
It is worth noting that hair loss can be caused by various factors, including medical conditions, hormonal dysregulation, infection, family history, genetics, stress, and medication. Therefore, it is recommended to consult a healthcare professional to determine the cause of hair loss and develop a treatment plan.

Micronutrient supplements
Micronutrients are essential for the normal hair follicle cycle, playing a role in cellular turnover and immune cell function. Deficiencies in certain micronutrients have been linked to hair loss, particularly in the case of non-scarring alopecia.
Vitamin D is essential for creating the cells that develop into hair follicles and supports a healthy immune system. Low vitamin D levels have been associated with hair loss, and supplementation is often recommended to correct this deficiency.
Iron is another critical micronutrient for hair health. It is responsible for carrying oxygen to hair follicles, supporting hair growth. Iron deficiency has been linked to hair loss, and iron supplements may be prescribed to address this issue. However, caution is advised as excessive iron intake can be toxic.
Vitamin C is necessary for the body to absorb iron from the diet effectively. Therefore, vitamin C supplements can be beneficial for individuals experiencing hair loss alongside iron deficiency.
Zinc is another micronutrient that has been linked to hair loss. Studies have shown that patients with alopecia areata and male pattern hair loss exhibit lower zinc concentrations. Supplementation with zinc has been found to have therapeutic effects in these cases.
While biotin, or vitamin B7, is often marketed as a hair growth supplement, there is insufficient data to support its effectiveness in treating hair loss.
It is important to note that while micronutrient supplements can address specific deficiencies, a well-rounded diet that provides all the necessary macro and micronutrients is generally the best approach to support hair health and prevent nutrient deficiencies that could contribute to hair loss.

Malnutrition and stress
Malnutrition, caused by nutrient deficiencies, can lead to hair loss. This occurs when the body does not receive adequate nutrients to support normal and healthy hair growth. For instance, deficiencies in multivitamins such as Vitamin C, Vitamin D, and Vitamin E, as well as minerals like iron, zinc, and protein, can result in thin and brittle hair or eventual hair loss. Vitamin C and E, for example, act as powerful antioxidants that help prevent damage caused by free radicals, thus aiding in hair regeneration and optimal growth. Similarly, iron plays a crucial role in maintaining healthy hair follicles and ensuring proper oxygenation, which is vital for hair health.
Stress is another factor that has been linked to hair loss in men. A 2013 study involving 92 male identical twins found a correlation between increased stress duration and hair loss. While the exact mechanism is not fully understood, it is believed that stress can disrupt the normal hair growth cycle, leading to hair thinning and shedding.
Furthermore, extreme dieting practices, such as crash dieting or very low-calorie diets, can induce malnutrition and stress on the body, resulting in hair loss. These diets may not provide sufficient calories or essential nutrients, leading to nutritional deficiencies that negatively impact hair health. Additionally, the physical and mental stress associated with extreme dieting can exacerbate hair loss.
To mitigate hair loss caused by malnutrition and stress, it is crucial to address nutritional deficiencies and manage stress levels effectively. Ensuring a balanced diet rich in essential nutrients, such as vitamins, minerals, and proteins, can promote healthy hair growth and prevent further hair loss. Additionally, incorporating stress management techniques, such as exercise, meditation, or therapy, can help reduce the negative impact of stress on hair health.
In summary, malnutrition and stress are interconnected factors that can contribute to hair loss in men. By addressing nutritional deficiencies and managing stress, individuals can take proactive steps to support healthy hair growth and reduce the risk of hair loss.

Smoking and alcohol
Smoking, on the other hand, has been found to exacerbate and accelerate hair loss, particularly in male pattern baldness. Nicotine and other chemicals in cigarettes can damage hair follicles and affect the hair growth cycle. People who smoke an average of 20 cigarettes a day are twice as likely to experience moderate to severe hair loss. Additionally, secondhand smoke from a partner or an open fire can also contribute to hair damage.
Both smoking and alcohol can negatively impact overall health and well-being, and their effects on hair loss are a reminder of the importance of maintaining a healthy lifestyle. Quitting smoking and reducing alcohol intake can help slow down hair loss and improve overall health outcomes.
