What should you know about selenium hair loss?

Short answer

Selenium is needed in small amounts, but excess supplementation can harm hair and health; hair loss needs an assessment of its wider causes.

This answers one question. It is not a diagnosis and does not replace an assessment by a licensed doctor.

At a glance

Supplement caution
More selenium is not a routine treatment for hair loss.
What diagnosis needs
Pattern, timing, scalp findings, medicines, and health history.

Selenium and shedding

Selenium supports normal body functions, but taking more does not automatically improve growth. Excess intake can cause hair or nail changes, stomach symptoms, a metallic taste, or a garlic-like breath odour. Supplements can also complicate the search for the real cause of shedding.

Hair loss may relate to inherited pattern thinning, an autoimmune process, illness or stress followed by shedding, scalp infection, or repeated pulling and tight styles. [Hair Loss](/symptoms/hair-loss/) is a symptom rather than one diagnosis.

Practical next steps

Do not start, stop, or increase selenium to treat shedding without reviewing your diet, supplements, medicines, and health history with a clinician. Take photographs of the scalp over time and note whether loss is diffuse, patchy, sudden, itchy, scaly, or associated with broken hairs.

A dermatologist may consider [Telogen Effluvium](/conditions/telogen-effluvium/), [Male Pattern Hair Loss](/conditions/androgenetic-alopecia/), [Female Pattern Hair Loss](/conditions/female-pattern-hair-loss/), [Alopecia Areata](/conditions/alopecia-areata/), or [Scalp Ringworm](/conditions/scalp-ringworm/). Treatment depends on the finding.

When to seek care

Book a medical assessment for sudden loss, smooth patches, scalp pain, scaling, pus, or eyebrow and eyelash loss. Seek urgent care for severe illness after a supplement, repeated vomiting, confusion, breathing trouble, or facial swelling.

Questions for your doctor

Ask whether your selenium intake is appropriate, which pattern of loss you have, whether tests are needed, how long recovery might take, and whether treatments such as [Finasteride Treatment](/treatments/hair-restoration/finasteride-therapy/) are suitable for you.

Questions people ask

Can too much selenium cause hair loss?

Excess selenium can contribute to hair and nail changes, so supplements should be reviewed rather than increased.
