الخلاصة
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
