TLDR  Low Vitamin D and its receptors might be linked to chronic hair loss in women.   
  The study, conducted three years ago, investigated the correlation between Vitamin D and Vitamin D receptors in chronic telogen effluvium (CTE), a common form of hair loss, in females. The research included 30 female patients with CTE and 30 control subjects. The researchers measured serum Vitamin D levels using ELISA and tissue Vitamin D receptor levels using PCR. The aim was to establish a correlation between Vitamin D and Vitamin D receptors in CTE.
