4. HAIR LOSS
Hair breakage and loss are commonly attributed to stress. However, other factors can also damage your hair. A deficiency in v D can cause severe hair fall. Alopecia is an autoimmune disease that is characterized by severe hair loss.
There is not much data to support this, but there may be a connection between alopecia and v D deficiency. Studies show that people with alopecia or female-pattern hair loss have lower levels of v D, which can be associated with severe hair loss.
