Physiological Association: Vitamin D, Ferritin, TSH and Diffuse Hair Loss in Tarhouna, Libya: A Cross-sectional Study
Keywords:
Thyroid stimulating hormone, Vitamin D, S. ferritin, diffuse hair lossAbstract
Background: From January to June of 2025, this study was conducted in Tarhuna laboratories with the aim of evaluating biochemical markers and their relationship to hair loss.
Materials and Methods: There were 414 intravenous blood samples taken from patients who participated in this study, and the device (I-Chromma II analyser, Boditech Med, South Korea, 2017) was used to measure TSH, while S. ferritin and vitamin D were measured by the device (Mindray CL-900i analyser, China, 2022). Data was analyzed using Microsoft Excel 2010 and SPSS version 27. A questionnaire was used to gather additional data.
Results: The study found that participants' iron stores decreased by 49.3%, or roughly 204 cases, and that patients' vitamin D levels were insufficient by 85.5%, or roughly 354 cases, of the total number of cases. Additionally, the study revealed that an average of 4.3% (18 cases out of 414 study participants) had a thyroid hormone deficiency.
Conclusion: The majority of patients have normal thyroid function, but there is a high prevalence of iron and vitamin D deficiencies. Ferritin, vitamin D, and TSH levels did not significantly correlate with diffuse hair loss in women.
Recommendations: According to the study, trichoscopic or biopsy-based evaluations should be used in longitudinal studies to track changes in hair loss over time. Additionally, it recommends measuring, zinc, cortisol, and androgen levels; determining the causes of hair loss; assessing the effects of genetic and environmental factors; and researching blood hormone levels.
