Can Turning Vegan Cause Hair Loss?

Turning to the ways and diets of vegans is becoming more and more common. There are so many vegans now that most restaurants make sure they have several vegan dishes in the quite likely event that a vegan turns up wanting food.

While being a vegan is a great and Noble thing to do, many have expressed fears that doing so causes hair loss. Today, we’re going to determine if there is any fact behind this fear.

If you would like to know, once and for all, whether turning vegan causes hair loss or not, then take a look at our findings below!

Temporary and Permanent Hair Loss

First of all, there are two different types of hair loss. We call these types temporary and permanent hair loss. Temporary hair loss can be cause by hundreds of different things. Usually, it is caused by dehydration or a lacking nutrient in your hair follicles. The missing nutrient or water causes the hair follicle to stop growing new hair, causing hair loss.

The reason this one is called temporary hair loss is because you can still fix the problem. The hair follicle is very much alive and will continue growing new hair as soon as it gains the necessary nutrient or water that was missing.

Permanent hair loss occurs when your hair follicle does completely. A dead hair follicle will never produce hair again, no matter what you do to it. MPB or male pattern baldness is one example of permanent hair loss.

Effects of Sudden Change in Your Diet

When turning from a regular diet to a vegan diet, you are denying your body certain nutrients that it is used to, such as proteins from meat and dairy. The lack of protein in your system has an impact on your hair follicles.

When this happens, your hair follicle may stop producing hair for some time, causing temporary hair loss. When this happens, you will either have to wait until your body adapts to the changes and compensates for the different nutrient balance or use supplements to get the necessary nutrients into your hair follicles.

If left unchecked for too long, there is a possibility that temporary hair loss can become permanent hair loss. While there is no factual evidence of this, better to be safe than sorry!


Hyperthyroidism is another cause of both temporary and permanent hair loss. Unfortunately, one of the main causes of hyperthyroidism is eating large amounts of soy. It is very difficult to have a stable, balanced vegan diet without using a fair bit of soy to counteract your lack of dairy.

It doesn’t affect everyone, but some people develop hyperthyroidism during the early days of their vegan diet. There are ways and medications to handle it, but you need to be careful. Hyperthyroidism causes more problems than just hair loss, so make sure you inform your doctor straight away.

In the event that you do not deal with your hyperthyroidism, you may end up with permanent hair loss. Based on this fact and the previous dietary information, it is very likely that turning vegan could cause hair loss. The process will not be immediate, and it won’t occur with everyone who eats on a vegan diet. However, you should keep track of your health as you do that just to be safe!

Our Conclusions on Veganism and Hair Loss

The accusation that turning vegan causes hair loss is not accurate. It is quite possible to be vegan and still have healthy hair.

However, one could easily admit that turning vegan without any idea about the risks of your sudden diet change is dangerous both to your hair and your overall health. People who suddenly turn vegan without any warning and completely alter their typical diet, especially if their previous diet involved a good amount of meat, are bound to have issues such as hair loss.

Luckily, these occurrences are only temporary, so you still have time to correct them. If you have experienced sudden hair loss after turning to a vegan diet, all you need to do is take supplements for the proteins and vitamins you are now not getting. Over time, you will start to see your hair growing back and getting stronger again.
