What Is Fasting

Fasting is a change in eating pattern wherein an individual eats at the same time daily and stops eating at the same routine regularly. It is a religious obligation in many religions like Islam. It can also be adopted intentionally to lose weight or control diabetic symptoms.

Fasting has a long history in certain communities. There are two main schedules of fasting:

1- Eating Period

2- Restricted feeding period

During the first schedule, individuals eat enough food to stay active for restricted feeding periods. In some cases, the eating period starts in the evening and ends the next morning. The restricted hours are no more than 18 hours all around the world.

Can Fasting Cause Hair Loss

The short answer to this question is NO, fasting does not impact hair growth. It is just a change in eating routine.

But if you don’t take enough water and minerals, you can suffer from hair loss. Fasting can indeed affect your overall health. In the case of undiagnosed diseases, it can affect your hair as well as scalp health.

Fasting does not directly impact your hair health. Its indirect benefit is to boost overall health by regulating hormonal balance. If your health is good, your hair will also grow fast indirectly. We can’t ignore the indirect impact of fasting on their growth.

For hereditary patterns of baldness, fasting can be a contributing factor. It helps to repair body cells effectively by regulating hormone levels. It can also help in fighting against DHT sensitivity and scalp diseases in pattern baldness.

Why do you suffer from hair loss in intermittent fasting?

There are several reasons for hair fall during fasting.


Less sleep may cause anxiety. The stress level or cortisol level increases. If your diet changes, you feel stress and sleep loss. It is unhelpful and causes a mood disorder

Sleep loss

Any drastic change in food patterns can reduce your sleep. Several studies have shown that fasting can decrease REM sleep. This sleep is necessary to boost your memory, mode, and learning capacity.

Cortisol level

High cortisol level is also associated with fasting. When you can’t sleep well, you feel anxiety. As a result, cortisol or stress hormone increases.

Calorie Deficit

Fasting restricts calories. It upsets your hormones that play a crucial role in hair growth. It may also result in excess androgen which is unhealthy. In pregnancy when women restrict calorie intake, they may suffer from acne or hair loss.

Fasting and Temporary Hair Loss

One of the major side effects of fasting is hair loss. The good news is that it is temporary due to many internal and external factors.

This type of hair loss is known as telogen effluvium. It occurs when the hair growth cycle is temporarily interrupted. This condition may result in hair shedding, loss of hair volume, and slow hair growth. Moreover, hair follicles stop growing in this phase.

It’s a distressing condition.

There is nothing to worry about. The main reason is a change in eating patterns. When your body adapts to these changing conditions, the hair growth cycle will start again.

The main point is that this condition is temporary and will go away sooner. But if you feel hair loss for more than 8 weeks, it’s time to consult a doctor.

How to Prevent Hair loss When Fasting: 5 Tips

Whether it’s intermittent fasting or religious fasting, hair loss is a common side effect. The key fact is that it is temporary and preventable. If you take certain preventive measures, you can prevent temporary or permanent hair loss both in fasting. Let’s see what these measures are

 1-Take Vitamin Rich Food

There are no specific rules in fasting about what to eat. It’s all about when to eat. So you’re free to choose whatever you want to eat in your feeding hours. Include vitamin A, B, C & E in your diet during feeding hours.

Don’t forget to take a vitamin supplement daily. This vitamin code includes 6 mg of iron, vitamin B-12, and folic acid for women’s health. It will prevent hair shedding not only in fasting but also without fasting.

2-Control Mineral Deficiency

Another major reason for hair loss in fasting is mineral deficiency. When we restrict our body to stay without eating for long hours, our body reacts differently. Our cells may not receive enough Montreal to grow well. This also happens with cells in hair follicles that stop growing.

Minerals like zinc, iron, and selenium are involved in cell growth. The deficiency of these minerals may also lead to hypothyroidism. If you want to overcome the mineral deficiency in fasting, take this hair growth supplement.

3-Do Not Fast Too Long

It’s unhealthy to extend fasting time beyond 18 hours. Fasting from 18 to 20 hours can accumulate toxins in your body. Our body has a self-mechanism to replace toxins. When we fast too long, we actually don’t fuel our bodies. If you are doing so, change your fasting type and duration. It will be helpful to prevent hair loss also.

4- Go for Intermittent Fasting

If your hair is falling during fasting it does not mean you should stop fasting. It’s better to adopt a different type of fasting such as intermittent fasting. You should have feasting days to overcome mineral as well as vitamin deficiency. It is also helpful in decreasing toxin overload.

5- Identify Thyroid Level before Fasting

It’s important to check your thyroid hormone level before fasting. Low thyroid or hypothyroidism is a contributing factor to promote hair loss. If you are not producing TSH hormone, you may suffer from hair loss from fasting quite vigorously. It’s important to identify triggers that are sabotaging your hair during fasting.
