  • Stress
  • Dandruff
  • Vitamin and nutrient deficiency
  • Hormonal changes like those in pregnancy, puberty, and menopause 

While there are many different reasons that could cause hair loss, hair loss from vitamin deficiency is a common cause for many. 

Among the vitamin deficiencies that cause hair loss, vitamin D deficiency hair loss is perhaps the most common. Studies show that the link between vitamin D and hair loss is definitely there since its deficiency can cause alopecia (the clinical term for hair loss). 

Vitamins, especially vitamin D, can help in the creation of new hair follicles, which can prompt hair regrowth in individuals. Data also shows that vitamin D plays a role in hair follicle cycling, making it crucial for the health of your hair. 

Additionally, when your vital organs lack nutrients, they try to extract that nutrition from non-vital organs such as your hair, leaving it more brittle and weak. Which is why hair fall and vitamin deficiency are related.
