TLDR Korean women with female pattern hair loss have higher levels of ferritin, testosterone, and vitamin D than average.
The study conducted 9 years ago retrospectively evaluated 264 Korean patients diagnosed with Female pattern hair loss (FPHL). The study found that FPHL was most common in patients aged 20 to 29 years old, and 55% of the patients visited the hospital one year after the onset of FPHL. The levels of testosterone, hemoglobin, serum ferritin, 25-(OH) vitamin D, and thyroid stimulating hormone in FPHL patients were significantly higher than the average Korean adult women, while the free thyroxine level was significantly lower. Premenopausal FPHL patients showed significantly higher serum levels of hemoglobin, ferritin, and 25-(OH) vitamin D than those of the Korean adult women, but postmenopausal FPHL patients showed significantly higher serum levels of 25-(OH) vitamin D than those of Korean adult women. The study concluded that the levels of ferritin, testosterone, and vitamin D of FPHL patients were elevated higher than those of the Korean adult women.
