The Link Between Vitamin Deficiency and Hairloss


Many factors can affect hairloss, including proper nutrition.

Thinning hair and hairloss can be an alarming problem for both men and women. This can be caused by a variety of reasons like heredity, stress, or hormonal imbalances. Another possible cause of thinning hair is a nutrient or vitamin deficiency.

Your body needs the right amount of vitamins and minerals to function well. So if you are not getting the required amount of vitamins, or if your body is unable to absorb an adequate amount, it can negatively impact body functions like hair growth.

Deficiencies in these vitamins can affect hairloss and hair health:


Biotin is one of the most important nutrients in hair health because it enhances growth and thickens the hair shaft. A deficiency in biotin can result in split ends and brittle hair, causing hair to become thinner and unhealthy. Great dietary sources of biotin include liver, eggs, and dairy products.

Vitamin A and Beta-Carotene

This vitamin plays an important role in the health of your nails, skin, and hair. Vitamin A is used by the scalp to produce sebum, which lubricates hair roots and keeps hair from dryness, brittleness and breakage.

Beta-carotene, which is found in carrots and dark leafy greens, is converted by the body to create vitamin A.

Vitamin B6

This vitamin is responsible for stimulating hair growth due to its effect on blood circulation and cell building. Make sure your diet contains vitamin B6-rich foods like eggs, vegetables, whole grains, and liver.

 Vitamin E

Often referred to as the protector, vitamin E is essential to healthy blood circulation. When blood circulation is healthy, the hair follicles get the nutrients it needs to stay healthy. Olive oil, nuts, seeds and cooked dried beans (black, kidney beans, pinto, and garbanzo) are just some vitamin E-rich foods you can include in your daily diet.


A deficiency in iron can lead to anemia, which is one of the most common causes of hairloss in women. Good sources of iron include spinach, broccoli, lean beef cuts, and dark meat from chicken and turkey. Eating vitamin C-rich foods can also help increase absorption of iron.


When you’re not getting enough zinc, the function of the hair follicles are affected. If your hair follicles are not healthy, hair will not grow properly. Zinc also affects the androgen levels in men, which has been said to affect male hairloss. Whole grains, nuts, meats, seafood, and poultry are good sources of zinc.

A healthy, well-balanced diet is a good way to keep your hair healthy and fight hairloss from within. Not only are you taking care of your hair, you are caring for your whole body as well.
