The Institute of Medicine has determined that the needed daily intake of water for hair growth for men and women is somewhere between two and three liters.
The presence of toxins halters hair growth and can lead to a host of biological complications. It is therefore evident that there are immense benefits of water intake. So do not forget to chug down at least 8 glasses of water to banish all hair problems.
Water and your hair
Drinking enough water helps energize and support hair growth from root to tip. It also helps prevent split ends and a brittle hair texture, as well as fosters a healthier scalp meaning you'll have fewer chances of developing problems like dryness, itchiness, or dandruff.
Cold water improves blood circulation. This enables your roots and scalp to receive valuable nutrients to remain healthy. And hence, washing hair with cold water promotes hair growth.
"There are specific juices that can be beneficial for the health of your hair and scalp, including aloe vera juice, kiwi juice and cucumber juice." According to Synder, spinach is highly concentrated with vitamin B, which restores shine and promotes hair growth.
Here's the hard truth: Little can be done to permanently change the diameter of individual hair strands. Thickening products can do wonders to temporarily plump hair strands, but when it comes down to it, fine hair is genetic and can't be changed.
Believe it or not, but water makes up almost 25% of the weight of a single strand of hair. Drinking at least two liters of water a day will help the strength of your hair, increasing growth.

Dehydration halts hair growth. Water hydrates the hair cells, makes them work the way they are supposed to and this helps your hair grow long and strong. Not just that, it stays in place too. And with hydration, you help keep away hair loss.
With mild dehydration, your hair may not look as lustrous or healthy as it normally does. But with more severe dehydration, your hair may become thin, brittle, dry, and break off easily—leading to the appearance of thinning hair.
“Vitamins are essential for healthy hair growth and may help in preventing hair shedding and thinning,” says Michele Green, M.D., a cosmetic dermatologist in New York. “The best vitamins for hair growth include B vitamins, vitamin D, vitamin E, zinc, biotin and iron.
Sources of Biotin
Foods that contain the most biotin include organ meats, eggs, fish, meat, seeds, nuts, and certain vegetables (such as sweet potatoes) [2,12].
Tangling, knotting, frizz, dullness, breakage: these are all signs of very dehydrated hair. The good news? There are easy ways to treat and prevent not just the annoying symptoms of dryness, but the dry, dehydrated hair itself.
"Sudden thinning hair can be a symptom of anemia (low red blood cell count), hormonal issues especially related to events like pregnancy, or a thyroid disorder, which are all very common in women," says Dr. Peredo.
The bottom line. There's no strong evidence to support using biotin for hair growth or to prevent hair loss in people without a deficiency. Because hair thinning and poor hair growth are sometimes associated with a biotin deficiency, correcting a deficiency can help restore hair growth in some people.
Hair thinning causes can include aging, your genes, shifting hormones, and your diet. Learn what else might be playing a role. Whether you're a woman or a man, it's normal for your hair to thin as you get older, according to Cleveland Clinic.
