What the studies say
In a study with the US National Library of Medicine National Institutes of Health, an association with alopecia and iron deficiencies in women was investigated.
The study involved a group of 11 subjects and looked at data of haemoglobin levels of women without hair loss and those in the alopecia group.
The study concluded the alopecia group could be lacking in essential iron.
In another study the diagnosis of iron deficiency and its potential relationship to hair loss was looked at.
The study noted: “Iron deficiency is the world’s most common nutritional deficiency and is associated with developmental delay, impaired behaviour, diminished intellectual performance, and decreased resistance to infection. Several studies have examined the relationship between iron deficiency and hair loss and some suggest iron deficiency may be related alopecia.
“Although this practice is not evidence based per se, we believe that treatment for hair loss is enhanced when iron deficiency, with or without anaemia, is treated.”
