iron deficiency nonscarring alopecia ferritin hair loss

TLDR Women with hair loss may benefit from higher iron levels.

This systematic review and meta-analysis investigated the relationship between iron deficiency and nonscarring alopecia in women by analyzing 36 studies with a total of 10,029 participants. The findings indicated that women with nonscarring alopecia had significantly lower ferritin levels, with a mean difference of -18.51 ng/dL compared to women without the condition. The prevalence of low ferritin levels (10 to 15 ng/dL and below) was 21%. The study concluded that women experiencing hair loss could benefit from maintaining higher ferritin levels.
