According to the American Academy of Dermatology, losing about 50 to 100 hairs a day is not considered a cause for concern. But if you start to notice more hair falling out when you brush your hair, while you wash your hair, or on your pillow when you wake up in the morning, it could be a sign that your body is dehydrated.
Sheena Kapoor, a dermatologist in India, said that when the body is dehydrated, hair will lose its natural shine, become dry like straw, brittle, and difficult to style. Hair also loses its natural elasticity, and can break with just a light pull.
Dehydration reduces blood flow to the scalp, limiting the delivery of nutrients and oxygen to hair follicles. This reduces the ability of new hair to grow, while existing hair becomes weaker and more prone to falling out than normal.
Not only that, water also plays an important role in the cell regeneration process. Without enough water, the body will be slow to create new hair cells and have difficulty replacing damaged hair.
Make it a habit to drink water regularly throughout the day.

Hair also contains about 10-15% water. When the body is dehydrated, the water in the hair will be drawn out, making the hair more dry, less elastic and more brittle.
To prevent hair loss due to dehydration, you can make changes in your daily routine, according to the health site Healthshots (India).
Drink enough water
On average, an adult needs about 2.7 liters of water per day. Get into the habit of drinking water regularly throughout the day, carry a water bottle with you, and set reminders if necessary.
Replenish electrolytes when exercising a lot
If you are doing intense physical activity or are very dehydrated, drink coconut water or electrolyte drinks to replenish the minerals your body needs.
Eat foods with lots of water
Besides drinking water, you should eat fruits and vegetables with high water content such as watermelon, cucumber, orange, strawberry or lettuce to further support the process of moisturizing from the inside.
Limit drinks that cause dehydration
Coffee, tea, soda, and alcohol all have diuretic effects, which can cause your body to lose water more quickly. You should limit these drinks to keep your hair healthy.
Gentle hair care
You should limit heat styling, avoid tying your hair too tightly or using strong chemicals, because these factors will make your hair more prone to breakage.
