Does drinking water help hair growth? Hydration plays a crucial role in maintaining overall health, and when it comes to your hair, it's no different. 

Drinking enough water not only nourishes your hair from the inside out but also supports your hair follicles by promoting healthier and stronger growth.

In this article, we'll explore how water is a key ingredient to achieving lush, vibrant hair.

While staying hydrated is essential for maintaining overall health, there is no direct evidence suggesting that increased water intake promotes hair growth. The hair growth process is complex, involving a cycle of growth, transition, and rest—known as the anagen, catagen, and telogen phases. 

Although proper hydration supports general body functions, which indirectly benefits hair health, drinking water alone doesn't enhance the hair growth cycle. 

Hair relies on various nutrients like iron, zinc, and biotin for strength and resilience. While tap water might contain trace amounts of minerals, it's not a significant source of the nutrients essential for hair growth. 

Therefore, while it's crucial to drink plenty of water for overall health and a hydrated scalp, there's no proof that it accelerates hair growth. 

However, a well-hydrated body can prevent hair from becoming dry and brittle, supporting the natural vitality of your hair.

6 ways drinking water helps hair growth

Here are 6 ways drinking water helps hair growth:

1. Hydration energizes hair cells

Water acts as the primary energy source for all body cells, including those that affect hair growth and health. 

Proper hydration helps to nurture these cells and even assists in transporting essential vitamins to the follicle.

2. Water stimulates hair roots

The scalp and hair roots are filled with sensitive nerve endings. Water activates these nerves and other sensors, enhancing the natural vitality of the hair roots and promoting a healthy hair environment.

3. Prevents dandruff and thinning

Just as a plant needs water to thrive, so does your hair. Adequate water intake helps keep your scalp hydrated, warding off dandruff and reducing the likelihood of hair thinning.

4. Strengthens hair

Water makes up about 25% of the weight of a single hair strand. Drinking sufficient water contributes to hair strength, enhancing its growth and preventing brittleness and split ends.

5. Prevents dehydration-induced stopping of hair growth

Dehydration can stop hair growth entirely. It is essential to maintain moisture levels in the hair, as dryness can lead to halted growth and damaged hair ends.

6. Enhances energy transmission to hair ends

Drinking plenty of water ensures that energy is efficiently transmitted from the scalp to the hair’s ends. This hydration helps maintain a healthy scalp, potentially reducing hair issues like dandruff.

What hydrates hair?

To hydrate hair effectively, both internal and external hydration are crucial. Drinking enough water is essential, but incorporating certain oils like coconut oil can also significantly benefit hair health. Coconut oil, in particular, has been shown to strengthen hair fibers. 

Regularly oiling your hair with such oils can enhance scalp health, add moisture, and improve overall hair condition.

While maintaining hydration is key, it's also important to avoid over-washing your hair. Excessive shampooing can strip your hair of its natural oils, leading to damage and brittleness. 

Therefore, balancing hydration and hair care practices is essential for maintaining healthy, hydrated hair.

Does drinking more water thicken your hair?

Drinking water alone does not directly thicken hair; hair thickness is primarily determined by genetics, as well as factors like hormones and age. However, proper hydration supports your body's overall health, including hair health. 

Keeping hydrated helps your hair retain moisture, which is crucial in any climate and contributes to maintaining the natural texture and health of your hair. So, while drinking more water might not thicken your hair, it helps maintain its health and appearance, which is vital for anyone aiming for beautiful, healthy locks.

What are the benefits of staying hydrated?

Staying hydrated goes beyond just quenching your thirst—it plays a critical role in various bodily functions. Here’s how keeping up with your water intake can benefit you:

  • Maintains body temperature: Water helps regulate your body's temperature, which is especially crucial in hot climates or during physical activity.
  • Protects your joints: Water is a key component of synovial fluid, which cushions your joints, reducing the risk of damage.
  • Aids in waste processing: Hydration is essential for healthy digestion and helps your body flush out waste products like urine and perspiration.
  • Flushes out bacteria: Drinking enough water helps remove bacteria from the body, preventing potential infections.
  • Maintains electrolyte balance: Water helps balance important minerals and electrolytes, crucial for proper bodily functions.
  • Supports heart health: Proper hydration is vital for normalizing blood pressure and stabilizing heart function.

How much water should you drink for hair growth?

According to the University of Missouri System, you should drink an amount of water in ounces that equals half your body weight in pounds. Add an additional 12 ounces for every 30 minutes of exercise. 

Factors like climate, physical activity, and health conditions, including pregnancy, can influence your hydration needs. Whether it’s sweating on a hot day or combating dry air in winter, your water intake should adjust to meet your body’s demands.

What happens to your hair if you don't drink enough water?

Dehydration can have a significant impact on your hair, causing it to become dry and brittle. When your body lacks adequate hydration, the keratin that makes up your hair strands dries out, increasing the likelihood of breakage and stunting growth. 

The human body, which is composed of 60-80% water, relies on proper hydration to maintain cell health and reproduction. Without enough water, the cells responsible for hair growth cannot function effectively, leading to dry, withered hair and a disrupted natural growth cycle. 

Keeping your hair roots well-hydrated is essential as they are the primary channel through which water nourishes your hair.
