What ferritin level is needed for healthy hair?
Ferritin levels are often considered in the assessment of hair loss, but there is no universally agreed threshold required for healthy hair growth. Some clinicians consider levels below around 30 micrograms per litre to be associated with hair shedding, while higher levels may be targeted in certain cases. However, the evidence linking specific ferritin levels to hair growth outcomes is limited and not definitive.
Key points:
- Low ferritin levels may be associated with hair shedding, particularly when levels fall below around 30 micrograms per litre
- Some clinicians aim for higher ferritin levels when managing hair loss, although clear targets are not established
- Laboratory reference ranges indicate general health status and do not specifically define optimal levels for hair growth
- Hair loss related to iron deficiency may improve once iron levels are corrected, depending on the underlying cause
