What Vitamin Deficiency Causes Hair Loss?


One of the main reasons for hair loss is a deficiency of certain vitamins. The organ that controls hair growth (Integrumentary Systems) relies heavily on the nutrients from the body. In order to keep the organ functioning fully, certain vitamins are needed. When enough nutrients aren't supplied, the hair starts to become brittle and dry; which causes it to shed and break off. Other than that, new hair isn't stimulated to grow.

Vitamin A

Vitamin A is essential to keeping the Integrumentary System in a constant growing state. You can get the daily recommended allowances of Vitamin A from dairy products, pumpkin and dark green vegetables.

Vitamin D

Not many people know the benefits of getting enough Vitamin D to prevent hair loss. Individuals with Vitamin D deficiency often experience sudden hair loss, alopecia and rickets.


Biotin is found in egg yolks, chicken and yeast. It helps to thicken the hair strands to avoid shedding and breakage.

Vitamin B Complex

Vitamin B1, B2, B3, B5 and B12 are essential for the hair, nails and skin. A deficiency in these vitamins will result in thin and brittle hair that quickly breaks off on your pillow or in the shower.

Folic Acid

Folic acid has many benefits for the body, including the cell renewal of hair. Getting the recommended daily allowance of 400 mcg of folic acid will help the hair to continue to grow.
