Does Dehydration Cause Hair Loss? If So, How Can We Resolve It?




Our bodies and organs function well when they are hydrated and have access to water. Consequently, water plays a major role in improving our health and well-being. We still don't drink adequate amounts of water due to our busy daily schedules. Make sure you drink enough water each day. You can suffer from dehydration if you don't drink enough water. Dehydration can harm your skin, nails, body organs, and even your hair.

The effects of dehydration on the human body are depressing. The health of our hair and skin are greatly influenced by water intake, as well as our overall wellness. As a matter of fact, water hydrates the entire body, so all body parts, including the hair, are healthy.

Do you want to know how dehydration affects your hair? Without enough water, hair tends to become frizzy, dry, and brittle, and develop split ends. As a result, it breaks more easily and hampers further growth.

In today's post, we'll examine how water affects overall hair health and how dehydration causes hair loss.

Keep Hydrated - Why is it Important?

Healthy adults need around 2 to 4 liters of water per day. However, it depends on several factors, such as the climate where you live, your gender, your physical activities, and others.

Staying hydrated is vital for keeping your skin and hair healthy, so stay hydrated all day long. Consuming adequate water lubricates your body and rejuvenates your hair follicles. This leads to healthy hair growth. Thus, hydration is crucial for maintaining the health & luster of your hair.

The human body is 60 percent water, so you need to keep it well-hydrated to maintain its health. Healthy hair is also threatened by a well-hydrated body, as human hair absorbs around 13% of its weight in water.

How Are Dehydration and Hair Loss Related?

Is dehydration related to hair loss? Yes, it is. Contrary to common hair loss caused by stress and genetics, this occurs passively.

Water is vital to hydrate the human body while regulating the circulatory system and lubricating hair follicles. This further stimulates overall hair growth. After all, water plays the main role in providing necessary minerals and nutrients to the hair.

If there is an improper supply of water to hair follicles, it may result in hair getting dull, brittle, lifeless, dry, and easy to break. That’s how dehydration is one of the major side effects of hair loss.

Dehydration for a short period does not have significant consequences. It happens when the body tries to regulate water to keep the body healthy. But if water intake is not sufficient, hair will likely become dull, dry, and lead to breakage. But if it’s on low liquid resources, your hair’s physical appeal and overall integrity have to deal with unfortunate collateral damage.

So, it proves that dehydration causes hair loss. It may occur either due to breakage from hair roots, through breakage due to follicle dryness, or as blood circulation slows down. Eventually, these conditions impact the hair integrity while leading to hair loss.

How to Recognise the Signs of Dehydration?

Dehydration may develop due to urination, sweating, illnesses, diarrhea, or vomiting. Some simple things like forgetting to drink water are also present in the common causes of dehydration.

Some common signs of dehydration are:

  • Xerostomia (dry mouth)
  • Dizziness
  • Tiredness and fatigue
  • Intense feelings of thirst
  • Dry skin
  • Infrequent urination
  • Dark-colored urine
  • Excessive sweating


If you are severely dehydrated, you will likely experience a rapid heartbeat, confusion, lack of urination, or excessive sweating. Severe dehydration also affects blood supply and oxygen supply to your organs, potentially leading to shock.

Extreme dehydration is also life-threatening. And in this case, you may require emergency medical help as soon as you develop symptoms of severe dehydration.

Preventing and Treating Hair Loss from Dehydration

The key to hydration is not a secret anymore. You have to drink adequate water all day long.

Follow the 8x8 rule or simply drink eight glasses of water every day. Many people find it an easy goal to achieve. You will need to drink more water if you live in a humid or hot region.

As per the Institute of Medicine (IOM), you should maintain a total daily water intake of 3.7 liters in the case of men and 2.7 liters of water for women. By making a few simple lifestyle changes, you can make things easier while keeping your hair, skin, and body well hydrated.
