En conclusion

Research shows that women with pattern hair loss often have lower vitamin D levels, but supplementing with vitamin D alone is unlikely to significantly improve this condition — it may be one supportive factor among many.

  • Lower vitamin D levels are consistently found in women with pattern hair loss
  • Supplementation alone is less effective than established options like minoxidil
  • Vitamin D receptor gene variants may influence susceptibility
  • Maintaining adequate vitamin D may support overall hair health but is not a standalone solution
