Does Water Help Hair Growth? Does It Really Work?

The human body is about 55-60% water, highlighting the crucial role of hydration for overall health, including hair vitality. But does water help hair growth? Absolutely. When we don’t drink enough water, our body prioritizes essential organs like the brain, kidneys, liver, and digestive system.

Consequently, areas like our skin and hair are the first to experience the effects of dehydration, leading to hair damage and loss. This shows why maintaining adequate water intake is essential for healthy hair growth.

Does Water Help Hair Growth?

Yes, water does help hair growth! Staying hydrated allows your body to perform at its best, enabling all systems, including your hair, to function optimally.

When you drink enough water, your hair is more likely to grow healthy and strong, as hydration prevents it from becoming dry and brittle. So, if you’re aiming for luscious locks, keeping up with your water intake is key.


  • Drinking enough water not only helps keep your hair healthy but also improves your skin’s look and feel.
  • Try eating more hydrating foods like fruits and vegetables to help stay hydrated.
  • Using a humidifier can also help keep your hair and skin moist, especially in dry climates or during winter.

Understanding the Importance of Water for Your Hair

Proper hydration means having enough water for your body’s needs, ensuring that all cells, tissues, and muscles function effectively. The required amount of water can vary based on factors such as age, gender, activity level, and perspiration. Therefore, some individuals might need more than the commonly suggested “eight cups a day.”

When you’re properly hydrated, you’ll have steady energy, smooth digestion, good focus, and pale yellow urine that’s almost clear. It’s easier to notice when you’re dehydrated because feeling thirsty means you’re already lacking water.

How Drinking Water Boosts Hair Growth

Drinking water benefits your scalp and hair in several ways. Just like your body, your hair contains a lot of water. Staying hydrated helps replenish your body’s cells and stimulates your hair follicles by aiding in the absorption of vitamins and minerals.

Getting enough water keeps your hair hydrated, preventing issues like itchiness, dandruff, and dry or brittle hair. A hydrated scalp remains healthy, helping you avoid thinning hair and hair loss.

Dehydration dries out your scalp and stops hair growth immediately. Dry hair is more prone to split ends and breakage when brushing or combing.

Water also boosts the energy transmitted from the scalp to your hair follicles, stimulating hair growth. When your scalp, follicles, and hair roots are hydrated, your scalp conditions improve, allowing you to grow strong, healthy hair that is less likely to break.

Additionally, water helps flush toxins from your body. Accumulated toxins can impair your body’s functions and negatively impact hair growth. Drinking enough water removes these toxins, benefiting your hair’s health.

How Drinking Water Boosts Hair Growth 

Hydrated hair absorbs water, making it look thicker and fuller. In contrast, dehydration can make your hair dull, lifeless, and limp. Water not only gives you the appearance of fuller, thicker hair but also increases your hair’s density. Keeping your body hydrated improves blood circulation and nutrient absorption, both essential for growing healthy hair.

In addition to drinking plenty of water, eating fruits and vegetables with high water content, and consuming coconut water or fruit juices can provide extra fluids along with vital minerals and vitamins.

How Water Helps Hair Grow

Water Maintains a Healthy Scalp

Proper hydration ensures that the scalp stays moisturized and supports the growth of new hair strands.

Keeping the scalp clean and hydrated from both the inside and outside helps prevent dryness, dandruff, and other skin irritations caused by a lack of water.

Water Strengthens Your Hair

Staying hydrated helps prevent split ends and brittle hair, reducing the risk of damage and breakage. Water strengthens hair from the root to the tip, supporting vitamin absorption, which is crucial for hair growth.

It also regulates the circulatory system, making it more efficient in delivering important nutrients to all your follicles, thus aiding hair growth. Additionally, water activates the nerve endings and sensors in the hair roots, increasing your hair’s natural vitality.

Water Flushes Pollutants and Toxins From Your Hair

Hydration works in two ways: it cleans your hair of dirt, debris, and sediment, and it stimulates a healthier detox from the inside through your liver, kidneys, and skin.

Using a water filter can also ensure you wash your hair with the cleanest water possible.

You’ve probably heard that you should drink 8-12 cups (about three liters) of water a day. However, these are just general guidelines, and the actual amount can vary depending on several factors.

According to the University of Missouri System, you should drink a number of ounces of water equal to half your body weight, adding another 12 ounces for every 30 minutes of exercise you plan to do. Of course, factors like pregnancy or health conditions can also affect how much water you need.

The environment can impact your water consumption needs as well. Hot summer days can increase your hydration needs due to sweating, while dry winter air may also require you to drink more water to keep your nose, throat, and sinuses functioning well.


Proper hydration is vital not only for your overall well-being but also for maintaining the health of your hair. Every cell in your body, including those that contribute to hair growth and vitality, relies heavily on water to function effectively. Without adequate water, these cells struggle to perform their essential tasks, which can lead to weakened hair growth and increased hair breakage. So, does water help hair growth? Absolutely.

Ensuring you drink enough water daily can profoundly influence the strength, shine, and overall health of your hair. Remember to keep hydrated – it’s a simple yet powerful way to boost your health and give your hair the best environment to thrive. Make hydration a priority and watch as your body, and particularly your hair, benefits from this fundamental yet crucial habit.
