A Glamour UK report outlines seven nutrients and supplements promoted for hair growth, while experts stress that benefits depend on the cause of hair loss. They recommend checking for deficiencies before supplementing; evidence does not show that extra nutrients reliably improve growth when levels are already adequate.
A Glamour UK report has outlined seven vitamins and supplements that experts say may support hair health, while emphasizing that they are most likely to help when hair loss is linked to a confirmed nutrient deficiency. The guidance matters to people considering over-the-counter products: experts caution that supplements are not a guaranteed fix and advise checking nutrient levels and identifying the cause of hair loss first.
The report identifies iron, vitamin D, zinc, B vitamins, biotin, vitamin E and saw palmetto among the nutrients and ingredients discussed for hair health. It does not establish that every person experiencing shedding should take them. The experts cited say effects depend on the underlying cause, and supplementation may have modest benefits when hair loss is unrelated to nutrition.
Several experts describe specific links between low nutrient levels and hair changes. Dermatologist Aamna Adel says correcting low iron or ferritin can support hair follicles, while nutrition therapist Rhian Stephenson cautions against taking high doses of iron without a test. Adel says vitamin D is worth addressing when levels are low; Stephenson says extra vitamin D has not been shown to boost growth when levels are already adequate. Stephenson also says zinc supports normal follicle function, and that B12 and folate play roles in cell division and DNA synthesis.
The source material gives less detail about the evidence or recommended use for biotin, vitamin E and saw palmetto. It quotes dermatologist Danilo Del Campo saying saw palmetto may target dihydrotestosterone, or DHT, a hormone associated with hair loss. That is an expert description of a possible mechanism, not proof that the ingredient will produce hair growth for an individual. The report does not provide product-by-product clinical comparisons or establish a ranking among the seven options.
Why Testing Should Come First
The report’s main practical point is that hair shedding has multiple possible causes, so choosing a supplement by popularity alone may miss the issue. Experts cited name illness, stress, rapid weight loss, iron deficiency, thyroid problems, hormonal changes and genetic hair thinning as possible contributors. Identifying the cause can help people avoid spending money on a product that is unlikely to address it.
Supplement safety also matters. Too much vitamin A or selenium can contribute to hair loss, according to Del Campo, and high-dose iron should not be taken without evidence of need, Stephenson says. A medical professional can assess symptoms and decide whether testing or other treatment is appropriate. The report says some people may need options beyond supplements, including topical or oral medication under a clinician’s guidance.

Hair Loss Has Several Triggers
The report describes telogen effluvium as a common form of temporary, widespread shedding that may start months after a physical or emotional stressor. Examples cited by Dr. Naomi Newman-Beinart include illness, surgery, significant weight loss and a particularly stressful period. Hormonal changes around perimenopause and menopause may also affect hair, as can genetic forms such as female-pattern hair loss.
Experts cited say deficiencies in iron, vitamin D, B12 or zinc can be relevant for some people. But Michele Green, a board-certified cosmetic dermatologist, says hair loss caused by vitamin deficiency is relatively uncommon in developed countries because many people get needed nutrients from a balanced diet. She identifies people on restrictive diets, including some vegan diets, as a group who may need closer attention to nutrient intake. These comments do not amount to a diagnosis for any reader.

What Supplements Cannot Establish
The source material does not provide clinical trial results, product comparisons, dosage guidance or a publication date. It therefore cannot establish that these seven options work equally well, that any one product is best, or that supplements will help someone whose hair loss has another cause. The report also does not specify how often testing should be repeated or which tests are appropriate for each person.
Some claims describe associations or possible mechanisms rather than demonstrated outcomes. It remains unclear from the supplied material what evidence supports each ingredient individually, including biotin, vitamin E and saw palmetto. Readers should not treat the list as a diagnosis or personalized treatment plan.
Discuss Symptoms With a Clinician
The report recommends that people concerned about hair loss speak with a medical professional and have relevant nutrient levels checked before starting supplements. A clinician can consider potential causes, including medication effects or underlying health conditions, and advise whether testing or treatment is appropriate. People taking medicines or managing a health condition should ask a qualified professional about supplement safety and possible interactions.
For persistent or worsening shedding, the next step is an individualized assessment rather than assuming a vitamin deficiency. The source does not announce a follow-up study, product evaluation or clinical recommendation; the evidence and advice presented remain limited to the experts and material included in the report.
Key Questions
Do hair growth vitamins work for everyone?
No. The experts cited say supplements may help when hair loss is linked to a nutrient deficiency, but benefits may be modest when the cause is genetic or otherwise unrelated to nutrition. They are not a guaranteed treatment.
Which deficiencies may affect hair?
The report discusses low iron or ferritin, vitamin D, B12 and zinc as possible contributors to hair problems. A clinician can determine whether testing is appropriate and interpret the results.
Should I take iron for hair shedding?
Not without establishing that it is needed. Rhian Stephenson advises testing first and cautions against high-dose iron unless a deficiency is present. Ask a medical professional for guidance.
Can supplements replace medical treatment for hair loss?
Not necessarily. The report says some people may need treatment beyond over-the-counter supplements, depending on the cause. A dermatologist or other qualified clinician can discuss suitable options.
