Iron
Iron deficiency is globally prevalent and significantly impacts hair loss. Serum ferritin, an iron-binding protein, is a key indicator of body iron levels and is critical in hair loss research. However, its levels can be misleading in certain medical conditions like inflammation or liver disorders.
Iron deficiency is notably common among women experiencing hair loss, though the correlation between low serum ferritin levels and hair loss remains a topic of debate. Research varies on defining iron deficiency for hair loss, with different studies proposing serum ferritin cut-off levels ranging from 15 to 70 µg/L. To address severe hair loss due to Telogen Effluvium (TE), maintaining serum ferritin above 40 or 70 ng/dL has been suggested. Despite this, evidence on the effectiveness of iron replacement therapy in TE treatment is limited, although some controlled studies show benefits.
Menstruation is a major cause of iron deficiency in healthy premenopausal women. This has led to questions about the lower reference ranges for female serum ferritin, which may be skewed due to widespread iron deficiency.
The role of essential amino acids, especially L-lysine, in iron uptake and hair growth is under investigation. Adding L-lysine to iron supplements has shown significant increases in serum ferritin levels in some studies.
Research on the relationship between hair loss and iron deficiency primarily focuses on non-scarring alopecia in women. Studies suggest a possible link between iron deficiency and various types of hair loss, including TE, Alopecia Areata (AA), and Androgenetic Alopecia (AGA), though some studies contradict this.
The relationship between AA and iron deficiency is not strongly supported by research. A study on premature graying in young individuals showed a potential role for calcium, ferritin, and vitamin D3 levels.
The hepcidin hormone, regulating iron absorption, is linked to hair loss. A mutation in the TMPRSS6 gene, affecting hepcidin levels, was found to cause iron deficiency and hair loss in a study on mice, which was reversible with iron supplementation.
The influence of iron on hair follicle gene expression is an emerging area of study. It’s hypothesized that iron deficiency might alter the hair growth cycle, but this needs further exploration. The study by Rushton suggests that a subset of women with CTE might be particularly affected by changes in hepcidin-induced hair follicle regulation, particularly when serum ferritin is below the lower male reference range.
Overall, while iron’s role in hair loss is evident, the complexity of its interaction with various factors and the need for more research make it a nuanced topic in hair loss studies.

Selenium
Selenium, necessary for synthesizing over 35 proteins, including the antioxidant enzyme glutathione peroxidase, becomes deficient in certain conditions, such as in low-birth-weight infants or those on total parenteral nutrition (TPN). Research by Venton et al. showed that patients on TPN without selenium supplementation experienced hair pigmentation loss, a condition which improved with selenium therapy.
While selenium is essential, its availability in various foods, including meat, vegetables, and nuts, typically meets daily requirements. Excess selenium intake, however, can lead to toxicity, manifesting as symptoms like nausea, vomiting, hair loss, and other issues. A notable incident of selenium toxicity from a dietary supplement underscores the importance of cautious selenium consumption. This abstract underscores selenium’s crucial role in maintaining hair health and the fine balance required in its intake.

Zinc
Zinc plays a role in hair tissue growth and repair. It also helps keep the oil glands around the follicles working properly.
Zinc, a vital trace element, is crucial for human health as the body cannot produce it independently and relies on dietary sources like fish and meat. A deficiency in zinc often arises from diets heavy in cereal grains, low meat consumption, certain medical conditions, and specific dietary practices. This deficiency is notable in several groups, including those with anorexia nervosa, individuals suffering from gastrointestinal disorders, alcoholics, and pregnant women, due to either reduced intake, increased loss, or higher metabolic demands.
Research has established a clear link between zinc deficiency and hair loss, with hair regrowth observed following zinc supplementation. However, studies investigating the correlation between zinc levels and various types of hair loss, such as Telogen Effluvium (TE) and Androgenetic Alopecia (AGA), show mixed results. Some studies report lower zinc levels in patients with Alopecia Areata (AA) and TE, recommending zinc replacement in cases of significant deficiency. Conversely, other research finds no notable difference in zinc levels between individuals with Chronic Telogen Effluvium (CTE) and healthy controls.
The efficacy of zinc supplementation in treating hair loss also remains a topic of debate. While some studies report positive outcomes with zinc supplementation in AA patients, others show no improvement. This inconsistency suggests the need for further research to clarify the role of zinc in hair health and its potential as a treatment for various hair loss conditions.
Foods high in zinc include beef, spinach, and pumpkin seeds. Men require 9.5mg and women 7mg per day.
Addressing hair loss through nutrition
Improving dietary habits can significantly impact hair health. However, supplements should only be considered when dietary changes are insufficient and under medical guidance. MHRA and NHS provide guidance on the safe consumption of supplements.
Hair loss FAQs
-
Can changing my diet reverse hair loss?
While dietary changes can improve hair health, they may not reverse hair loss caused by genetic or hormonal factors.
-
Are there any risks associated with taking hair supplements?
Over-supplementation can lead to adverse effects. It’s important to follow prescribed dosages.
-
How long does it take to see improvements in hair health after dietary changes?
It can take several months to notice changes, as hair growth is a slow process.
What is the best treatment for hair loss?
- Minoxidil (Rogaine): An over-the-counter topical treatment that can slow hair loss and stimulate hair growth in both men and women. Minoxidil is available to buy from The Family Chemist.
- Finasteride (Propecia): A prescription pill mainly used by men, which can slow hair loss and even lead to regrowth in some cases. Finasteride is available to buy from The Family Chemist.
- Hair transplant surgery: Involves moving hair from a thickly haired area of the head to areas with thinning hair.
- Low-level laser therapy (LLLT): Can be used to treat pattern balding in both men and women by enhancing cellular activity.
- Lifestyle Changes: A balanced diet, managing stress, and avoiding harsh hair treatments can help.
It’s important to consult a healthcare professional for a diagnosis and treatment plan tailored to your specific situation.
How do you fix thinning hair?
- Use gentle hair care products and avoid tight hairstyles.
- Consider OTC treatments like minoxidil.
- Ensure a balanced diet with adequate protein, vitamins, and minerals.
- Treat any underlying health conditions like iron deficiency or thyroid problems.
- Seek advice from a dermatologist for specific treatments.
Can you regrow hair?
The potential to regrow hair depends on the cause. If the hair loss is due to conditions like telogen effluvium (temporary hair thinning after a stressful event), normal growth usually resumes once the triggering event is resolved. However, with genetic hair loss (androgenetic alopecia), regrowth is more challenging and treatments like minoxidil or finasteride might help slow down the loss or partially regrow hair.
Is it possible to regrow hair after 40?
Yes, it’s possible, but it largely depends on the cause of hair loss. Pattern baldness, which is common as people age, can be treated with medications like minoxidil or finasteride. Hair transplant surgeries are another option. However, the effectiveness of these treatments can vary, and it’s crucial to set realistic expectations and consult a healthcare professional.
Remember, the effectiveness of treatment varies from person to person, and it’s always best to consult with a healthcare provider to understand the most suitable options for your individual situation. Additionally, for the most accurate and up-to-date information, refer to reliable sources and medical guidelines specific to your region, such as the NHS in the UK.
