1. Low Protein Intake
Protein is an essential nutrient for hair growth, as hair is primarily composed of keratin, a protein. A diet low in protein can lead to hair loss, particularly if the deficiency is prolonged. Hair follicles require adequate protein intake to produce new hair strands and maintain their structural integrity[^1^]. It is essential to incorporate sufficient protein sources in your diet, such as lean meats, fish, poultry, beans, and legumes, to support healthy hair growth.
2. Excessive Vitamin A Intake
While vitamin A is vital for hair health, excessive intake can lead to hair loss. High levels of vitamin A can cause hair follicles to enter the shedding phase prematurely, resulting in hair thinning and hair loss[^2^]. It is essential to maintain a balanced diet and avoid overconsumption of vitamin A supplements or foods high in vitamin A, such as liver and fortified cereals.
3. Zinc Deficiency
Zinc is a crucial mineral for hair growth and overall hair health. A deficiency in zinc can lead to hair loss, as zinc is involved in hair follicle formation and maintaining hair follicle integrity[^3^]. Foods rich in zinc include oysters, red meat, poultry, beans, nuts, and whole grains. Ensuring adequate zinc intake can help prevent hair loss due to nutritional deficiencies.
4. Iron Deficiency
Iron deficiency is a common cause of hair loss, particularly in women. Iron is essential for the production of red blood cells, which carry oxygen to hair follicles. A deficiency in iron can lead to hair loss, as hair follicles are deprived of oxygen and essential nutrients[^4^]. Incorporating iron-rich foods into your diet, such as red meat, spinach, lentils, and fortified cereals, can help prevent foods that cause hair loss caused by iron deficiency.
5. Sugar Consumption
High sugar consumption can cause inflammation and hormonal imbalances, which can contribute to hair loss. Sugar increases insulin levels, leading to an increase in dihydrotestosterone (DHT) production. DHT is a hormone that can cause hair follicles to shrink, resulting in hair thinning and hair loss[^5^]. Reducing sugar intake and choosing healthier alternatives, such as whole fruits and natural sweeteners, can help improve hair health.
6. Gluten Intolerance
For individuals with gluten intolerance or celiac disease, consuming gluten can lead to foods that cause hair loss. Gluten triggers an autoimmune response in these individuals, resulting in damage to the hair follicles and hair loss[^6^]. It is essential for those with gluten intolerance to avoid gluten-containing foods, such as wheat, barley, and rye, and opt for gluten-free alternatives to maintain hair health.
7. Inflammatory Foods
Inflammatory foods, such as processed foods, trans fats, and refined sugars, can contribute to hair loss. Inflammation can cause damage to hair follicles and impede hair growth[^7^]. Incorporating anti-inflammatory foods into your diet, such as fruits, vegetables, nuts, seeds, and fish, can help improve hair health and prevent hair loss.
8. Oxidative Stress
Oxidative stress occurs when there is an imbalance between the production of free radicals and the body’s ability to neutralize them. Free radicals can cause damage to hair follicles, leading to hair loss[^8^]. Foods high in antioxidants, such as berries, leafy greens, and nuts, can help combat oxidative stress and promote hair health.
9. High Mercury Levels
Certain fish, such as shark, swordfish, and king mackerel, contain high levels of mercury. Excessive mercury consumption can lead to hair loss, as mercury can disrupt the hair growth cycle and cause hair follicles to become inactive[^9^]. Opting for fish with lower mercury levels, such as salmon, sardines, and trout, can help prevent hair loss due to mercury exposure.
10. Red Meat
While red meat can be a good source of iron and protein, excessive consumption can lead to hair loss. Red meat is high in saturated fat, which can cause inflammation and disrupt the hair growth cycle[^10^]. Limiting red meat intake and choosing leaner protein sources, such as chicken, turkey, and fish, can help maintain hair health and prevent hair loss.
11. Foods High in Trans Fats and Hydrogenated Oils
Trans fats and hydrogenated oils are found in many processed and convenience foods. These unhealthy fats can cause inflammation, which may contribute to hair loss by damaging hair follicles and disrupting the hair growth cycle[^11^]. To maintain hair health, it is crucial to limit the intake of foods containing trans fats and hydrogenated oils, such as fried foods, baked goods, and packaged snacks.
12. Unhealthy Food and Fast Food
Fast food and other unhealthy food options are often high in calories, unhealthy fats, sugars, and chemical additives. These ingredients can contribute to inflammation, hormonal imbalances, and nutrient deficiencies, which can lead to hair loss[^12^]. Opting for healthier, whole food options and cooking at home can help promote hair health and prevent hair loss.
13. Dairy Products
Some individuals may experience hair loss due to a sensitivity to dairy products. Dairy can cause inflammation in some people, which can lead to foods that cause hair loss[^13^]. If you suspect that dairy is causing your hair loss, try eliminating it from your diet and replacing it with non-dairy alternatives, such as almond milk, coconut milk, and soy products.
14. Foods with High Glycemic Index
Foods with a high glycemic index, such as white bread, pasta, and rice, can cause rapid spikes in blood sugar levels. This can lead to inflammation and increased production of DHT, a hormone linked to hair loss[^14^]. Choosing foods with a lower glycemic index, such as whole grains, legumes, and vegetables, can help maintain stable blood sugar levels and support hair health.
15. Telogen Effluvium and Diet
Telogen effluvium is a type of hair loss characterized by diffuse hair shedding, usually triggered by a significant stressor, such as severe weight loss, illness, or nutrient deficiencies[^15^]. Ensuring a balanced diet rich in essential nutrients, particularly during periods of stress, can help prevent hair loss due to telogen effluvium.
16. Female Pattern Baldness and Diet
Female pattern baldness, or androgenetic alopecia, is a hereditary form of hair loss that affects women. While diet alone cannot reverse this type of hair loss, maintaining a balanced diet and addressing any underlying nutritional deficiencies can help support overall hair health and potentially slow the progression of hair loss[^16^].
17. Male Pattern Baldness and Diet
Male pattern baldness, or androgenetic alopecia, is the most common cause of hair loss in men. Although genetics play a significant role in this type of hair loss, diet can still impact hair health. Ensuring a balanced diet, rich in essential nutrients and low in inflammatory foods, can help support hair health and potentially slow down the progression of hair loss in men[^17^].
18. Nutrient Deficiencies and Hair Loss
Nutrient deficiencies, such as low levels of iron, zinc, vitamin D, and B vitamins, can lead to hair loss. Ensuring a balanced diet and incorporating foods rich in these essential nutrients can help prevent hair loss due to nutritional deficiencies[^18^]. If you suspect a deficiency, consult a healthcare professional for appropriate testing and guidance on supplementation, if necessary.
19. Hair Follicle Health and Diet
Maintaining healthy hair follicles is essential for hair growth and preventing foods that cause hair loss. A balanced diet rich in essential nutrients, antioxidants, and anti-inflammatory foods can help support hair follicle health and promote hair growth[^19^].
20. Hair Loss Due to Hormonal Imbalances
Hormonal imbalances, such as polycystic ovary syndrome (PCOS) and thyroid disorders, can contribute to foods that cause hair loss. Diet plays a crucial role in hormone regulation, and certain foods can exacerbate hormonal imbalances. Consuming a balanced diet, rich in anti-inflammatory and nutrient-dense foods, can help support hormone balance and potentially reduce hair loss related to hormonal imbalances[^20^].
21. Trichotillomania and Diet
Trichotillomania is a psychological disorder characterized by the compulsive urge to pull out one’s hair, leading to hair loss. While diet cannot directly treat trichotillomania, ensuring a balanced diet and addressing any underlying nutrient deficiencies can help support overall hair health and potentially reduce the impact of hair pulling[^21^].
