Ferritin is the main iron-storage protein in the body. Low ferritin (iron deficiency) can affect the skin: typical signs include pallor due to reduced hemoglobin, dry and brittle skin, and increased hair loss. Some individuals also report itching (pruritus) without visible skin changes. The underlying mechanisms involve impaired oxygen delivery to skin cells and reduced collagen synthesis. However, the link is not specific – many other factors (diet, hormones, underlying conditions) influence skin health equally. Evidence comes mainly from clinical observation rather than large controlled trials. A ferritin test alone is insufficient to explain skin issues; it should be interpreted together with a complete blood count and other iron markers (transferrin, hemoglobin). Consumer lab tests that only measure ferritin provide only a partial picture. For persistent skin changes, medical evaluation is recommended.
