Vitamin Deficiency Hair Loss

Role Of Vitamin Deficiency Hair Loss

Hair loss, or alopecia, is a common problem that most individuals face in their life. While ageing is the most common reason for hair loss, there are other factors at play too.


Some of these factors or reasons include,

Seasonal changes (hair starts falling towards the end of fall and during the winter)

Strong chemicals from the wrong hair products

Over usage of devices like hair straighteners and curlers

Lack of essential nutrients in the body

Hereditary or genes

In this blog, we will discuss the lack of nutrients and the role of vitamin deficiency in hair loss.

Hair Loss Due to Vitamin Deficiency


A balanced diet contains all the necessary nutrients, like vitamins and minerals, that your body requires. Maintaining a balanced diet every day helps you maintain a healthy life. If your daily diet lacks these essential nutrients, it causes a few problems.

There are different types of vitamins, like vitamin A, B, C, D, etc. Facing deficiencies in a few of these vitamins can lead to hair loss.

In fact, a deficiency in these nutrients and other minerals can cause chronic TE (a form of diffuse hair loss), androgenetic alopecia or male pattern baldness, female pattern hair loss (FPHL), and alopecia areata (patchy hair loss)

Vitamin D Deficiency

Of all the vitamins that are responsible for hair growth, vitamin D is probably the most vital. Vitamin D helps your body create new hair follicles. If your diet lacks the required quantity of vitamin D, your hair may stop growing and start thinning.

Dietary charts and references state that the Recommended Dietary Allowance (RDA) for most individuals up to the age of 70 is 15 micrograms. For adults above the age of 70, this value rises to 20 micrograms.

Apart from getting the proper intake of vitamin D from your diet, sunlight is another good natural source of vitamin D. Insufficient exposure to direct sunlight can also cause vitamin D deficiency, thereby leading to hair loss.

Vitamin B Deficiency

Just like various types of vitamins, there are many subcategories under vitamin B also. Vitamin B1, B2, B3, B5, B6, B7, folate and folic acid, and B12 constitute the eight different kinds of vitamin B.

Vitamin B7

Vitamin B7, or Biotin, enhances the keratin production in the hair and boosts the growth of hair follicles. While biotin deficiency is very rare, it can also cause hair loss.

Folate and Folic Acid

Most of the green and leafy vegetables are full of folic acid and folate. So, as long as you consume your greens daily, you should not face any problems. However, deficiency in folate and folic acid also causes hair loss.

The Opposite Effect

Until now, we discussed how a deficiency in a few essential vitamins could lead to hair loss and similar problems. But there is another extreme or end to this spectrum that is equally critical to know - over-consumption of vitamins or hypervitaminosis. Yes, over-consuming a few vitamins can also cause hair loss.

Studies show that Vitamin A activates the hair follicle stem cells and stimulates the anagen phase of the hair growth cycle (3). A deficiency in vitamin A does not lead to hair loss. However, high levels of vitamin A from over-consumption can cause hair loss

How Can You Avoid Vitamin Deficiency?


Natural Sources

Consuming a balanced diet with the necessary quantities of all these vitamins is the best way to avoid any deficiency. Fruits, green leafy vegetables, fish, etc., are all great food options that you can consume to prevent vitamin deficiency.

Standing under direct sunlight during the morning hours can also help you keep your vitamin D levels in check.

Vitamin Supplements

If you cannot maintain optimal vitamin levels in your body from natural sources, then you should consider taking a few vitamin supplements. These supplements complete your daily required nutrient intake.

The most important thing to know about supplements is to avoid over-consumption at all costs. As seen earlier, in the case of vitamin A, hypervitaminosis A can cause hair loss. But the damage can be even more severe with other vitamins.

For instance, over-supplementation of vitamin E, or hypervitaminosis E, can increase the risk of bleeding and decrease the production of thyroid hormones.

Health organizations and medical centres always recommend consulting a doctor or a medical expert before consuming any supplements. These experts can better guide you on the dosage of your vitamin supplements if you need them.

How to Prevent Hair Loss?

Apart from consuming vitamin and nutrient-rich food or supplements, here are a few extra tips that you can follow to prevent hair loss or stimulate hair growth.

Use mild hair products

Massage your scalp with essential oils

Avoid over-using hair styling devices and other appliances

Try and reduce your stress levels as much as possible

Drink lots of water and stay hydrated

Visit your dermatologist to know more about your hair fall and the treatment options available


In a nutshell, deficiencies in a few vitamins can cause hair loss along with other health-related problems. Over-consuming or over-supplementing a few vitamins can also lead you down the same path.

Besides vitamins, deficiency in other nutrients and minerals like iron, zinc, and selenium also causes hair loss.

Maintaining recommended levels of these vitamins and minerals in your body through a balanced diet or supplements is the only way to avoid any deficiency and hair loss. But make sure you consult a doctor or medical expert before you start on any supplements.
