Benefits of Water on Your Hair

So we’ve told you there are a lot of things water can do for your hair, but just what are they? Is it really worth it to make sure you’re drinking enough water, or is your water intake not really related to the appearance and texture of your hair at all? There are actually several different ways your hair and water are related, whether you’re talking about using water on your hair or drinking enough water in your day to day life. By understanding these factors, you’ll have the information you need to give your hair a fighting chance, even if it’s dry and brittle from dehydration. Here are a few different ways water can help your hair:

drinking water for hair loss

1. Keeps it clean

Okay, so this one might be a no-brained, but of course water does one very important thing for you hair. It keeps it clean! This is why it’s so important to wash your hair regularly. Washing your hair removes dirt that might be present there, but it also removes the oils and toxins that build up in your hair due to sweat and exposure to substances that can cause problems over time. If you use hair spray on your hair, then make sure you’re washing it out daily rather than letting it sit there. And no matter what you use on your hair, don’t go more than a couple of days in between showers for best results.

2. Drinking water encourages your hair cells to function properly

Whether you’re talking about washing or rinsing your hair or you’re discussing why it’s important to drink plenty of water every day, keep in mind that more water equals more hydration. And the more your cells are hydrated, the more they’re going to function properly. When you have properly-functioning hair cells, then your hair will grow more quickly and it will also become thicker, fuller, and more naturally voluminous too. You may not even need all those fancy hair supplies you’ve got on hand when you have enough water every day!

3. Dehydration may cause hair loss 

Although there are many other potential causes of hair loss and dehydration is not the only one, there is some correlation between being dehydrated and losing your hair, especially at an early age. The more water you have in your daily life, the more likely you are to keep your hair for longer. Again, water helps hydrate your hair cells, and when your hair cells work the way they’re supposed to, your hair grows thicker, longer, and stays in place more easily too. Staying hydrated can help you fight off the risk of hair loss in some instances.

4. Cold water is better for your hair 

When you’re rinsing or washing your hair, remember that you may be doing more harm than good if you’re using very hot water all the time. Although it can feel great to take a nice hot shower now and then, it’s better to wash your hair in cool or even cold water most of the time for best results. This goes doubly true of hair that you’ve treated with bleach or a color, but no matter what condition your hair is in, you should make sure you aren’t washing in water that is too hot. Hotter water damages hair and may even contribute to hair loss.

5. Hair absorbs 30% of its weight in water 

Did you know that when you wash your hair, go swimming, or even walk in the rain, your hair is absorbing around 30% of its weight in the water you’re exposing it to? Sometimes, hair even absorbs up to 50% of water! So as you can see, it’s important that you’re giving your hair access to the best water to help it grow and look its best. If you have very hard water in your home, you may want to think about putting in a water softener for your shower so you can keep your hair looking and feeling great.


Did you learn a little something about the relationship between water and your hair? You may not have even known there were so many different ways water can affect your hair, but it’s true. By paying attention to the way you use water on your hair as well as making sure you drink enough water every day, you can make sure your hair looks great, feels great, and stays just the way you want it to be for as long as possible.

But how can you know you’re doing the best you can for your hair? How do you know you’re drinking enough water to keep your hair in good condition? Here are a few signs your hair is getting the water it needs:

  • When your hair grows quickly, this is a good sign it’s well-hydrated. Hair that has access to enough water grows fast, and you’ll find yourself needing more frequent haircuts when you’re getting enough water.
  • If your hair looks shiny, it’s probably getting enough water—but double check. There is a chance your hair could look shiny because it’s too oily, but if you know that isn’t the case, then your natural shine is probably coming from the amount of water you’re getting in your daily life. And that’s a good thing!
  • Hair that stays strong through washing, brushing, and blow drying is getting enough water, too. If your hair is very brittle or it falls out easily, this means you’re dehydrated. It may also be a sign of some other health concerns, especially if it’s a new change, so make sure you speak to your doctor about it if you’re experiencing this.

Keep all this in mind the next time you wonder if you’re getting enough water for your hair. You may be surprised at the answer!
