The Role of Vitamin Deficiency in Female Hair Loss
Introduction to Female Hair Loss and Vitamin Deficiency
Hair loss in women, particularly chronic telogen effluvium (TE) and female pattern hair loss (FPHL), is a common concern that can significantly impact quality of life. Recent research has highlighted the potential role of vitamin deficiencies, particularly vitamin D and ferritin, in contributing to these conditions.
Vitamin D Deficiency and Female Hair Loss
Prevalence and Impact of Vitamin D Deficiency
Vitamin D deficiency is a widespread issue that has been linked to various health problems, including hair loss. Studies have shown that women with FPHL and TE often have significantly lower levels of serum vitamin D compared to healthy controls 145. For instance, one study found that the mean serum vitamin D levels in women with TE and FPHL were 28.8 ± 10.5 nmol/l and 29.1 ± 8.5 nmol/l, respectively, compared to 118.2 ± 68.1 nmol/l in controls .
Knowledge and Practices Regarding Vitamin D
A study conducted in Saudi Arabia revealed that while a majority of women were aware of vitamin D, only about 62.1% correctly identified its relationship with hair loss. Despite this awareness, only 40% of the participants were taking vitamin D supplements, indicating a gap between knowledge and practice 23.
Vitamin D and Post-COVID-19 Hair Loss
The COVID-19 pandemic has further complicated the issue, with recovered patients showing significant decreases in vitamin D levels, which correlated with increased hair loss. This suggests that vitamin D plays a crucial role in immune response and recovery, impacting hair health post-infection .
Ferritin Deficiency and Its Role in Hair Loss
Ferritin Levels in Hair Loss
Ferritin, a blood protein that contains iron, is essential for hair follicle health. Studies have consistently shown that women with TE and FPHL have lower serum ferritin levels compared to those without hair loss. For example, one study reported ferritin levels of 14.7 ± 22.1 µg/l in TE patients and 23.9 ± 38.5 µg/l in FPHL patients, compared to 43.5 ± 20.4 µg/l in controls .
Ferritin and Post-COVID-19 Hair Loss
Similar to vitamin D, ferritin levels were also found to be significantly lower in women experiencing hair loss after recovering from COVID-19. This further underscores the importance of maintaining adequate ferritin levels for hair health .
Broader Implications of Vitamin and Mineral Deficiencies
Comprehensive Nutrient Deficiency and Hair Loss
A systematic review and meta-analysis have highlighted that deficiencies in various micronutrients, including vitamins A, B, C, D, E, iron, selenium, and zinc, can contribute to non-scarring alopecia, which includes conditions like FPHL and TE. These nutrients are vital for the normal hair follicle cycle and immune function, suggesting that their deficiency could be a modifiable risk factor for hair loss 710.
Conclusion
The evidence strongly suggests that deficiencies in vitamin D and ferritin are associated with female hair loss, particularly in conditions like TE and FPHL. Addressing these deficiencies through dietary supplements and increased awareness could potentially mitigate hair loss in affected women. Further research and public health initiatives are needed to bridge the gap between knowledge and practice, ensuring that women are adequately informed and proactive about their vitamin intake.
