The Truth: The Surprising Connection Between Drinking Water and Hair Growth


Is Drinking Water the Secret to Longer and Healthier Hair?

Many of us have heard the saying, “water is the source of life” and it’s no surprise that water is vital for our overall health. But have you ever wondered if staying hydrated could also benefit your hair? The answer is yes! Drinking water doesn’t just help with keeping our bodies functioning properly, it has also been linked to aiding in hair growth and maintaining healthy locks. So, let’s dive deeper into the question: does drinking water help with hair growth?

The Science Behind Hair Growth

Before we can answer the main question, it’s important to understand the science behind hair growth. Each hair follicle on the scalp goes through three phases – anagen, catagen, and telogen. The anagen phase is the growth phase where hair follicles are actively producing hair. The catagen phase is a transitional phase where hair growth stops and the hair follicle shrinks. And finally, the telogen phase is the resting phase where the hair follicle rests before shedding and starting the cycle all over again.

Now, what does this have to do with water? Well, the average person loses around 80-100 hairs a day. But inadequate water intake and dehydration can disrupt this hair growth cycle. During dehydration, our bodies prioritize sending water and nutrients to vital organs, leaving hair follicles without enough hydration and nutrients to properly grow. As a result, hair growth may be stunted, and hair may become dry, brittle, and prone to breakage.

Water: The Key to Hydrated Hair

Just like our bodies, our hair needs water to function properly. Without enough water, our tresses can become dry and lifeless. Drinking enough water helps to hydrate the scalp and hair from within. This, in turn, results in shinier, healthier, and more luscious locks. Additionally, proper hydration can also improve the elasticity of hair, making it less prone to breakage and more likely to grow longer and stronger.

Besides its direct impact on hair growth, drinking water can also indirectly benefit our hair by helping to flush out toxins and waste. A buildup of these toxins can affect the health and vitality of our hair, leading to hair loss or damage. By staying hydrated and flushing out these toxins, we can promote a healthy environment for our hair to grow.

How Much Water Should You Drink?

So, we know that drinking water is important for our hair, but how much is enough? The recommended daily water intake varies for each individual based on factors like age, weight, and activity level. However, a general rule of thumb is to drink around 8-10 glasses a day or half of your body weight in ounces. For example, if you weigh 140 pounds, you should aim to drink 70 ounces of water daily.

It’s also worth noting that other factors can affect our water needs, such as sweating from exercise, hot weather, or alcohol consumption. In these cases, it’s important to replenish the lost fluids with additional water to avoid dehydration.

The Role of Diet in Hair Growth

While staying hydrated is essential for healthy hair growth, it’s not the only factor to consider. Our diet also plays a significant role in the health of our hair. Eating a balanced diet with a variety of nutrients, including vitamins, minerals, and protein, can help promote hair growth and prevent hair loss.

Vitamin A, biotin, and vitamin D are essential for maintaining healthy hair. Foods rich in these vitamins include carrots, eggs, salmon, and leafy greens. Iron is also crucial for hair growth and is commonly found in dark leafy greens, red meat, and legumes. Including these foods in your diet can help ensure that your hair receives the necessary nutrients for optimal growth.

Myth Busted: Drinking More Water Won’t Make Your Hair Grow Faster

While drinking water is necessary for healthy hair growth, it’s important to point out that it won’t make your hair miraculously grow overnight. Our hair’s growth rate is determined by genetics and other factors like age and hormone levels, and drinking excessive amounts of water won’t speed up the process. Staying hydrated and maintaining a healthy diet is just one piece of the puzzle for longer and healthier hair.


Drinking water does play a role in hair growth, but it’s not a magical cure. Along with staying hydrated, it’s essential to maintain a balanced diet, manage stress levels, and take proper care of our hair to promote its growth and health. However, staying hydrated is crucial for overall health and well-being, and who doesn’t love a little extra shine in their hair?
