The hair of all mammals follows this growth cycle, but we humans are unique in that our hair doesn't shed during hot weather and grow thicker during cold weather. In fact, in terms of hair growth at least, it appears that the opposite is true.
When you wash your hair with cold water, your blood capillaries open wider and there is a free flow of blood to your scalp. Through this, your hair roots receive all the essential nutrients from the blood, resulting in healthy hair growth.
Overusing hot water causes stress to your tresses, which can lead to frizzy, brittle and dry hair. Cold water, on the other hand, tends to trap moisture in the hair, resulting in excess moisture, making the hair look flat, with no volume.

“Washing your hair with cold water helps with closing your cuticle after the wash. This also has the added benefit of helping, along with your haircare products, to make your hair look strong and shiny, and who doesn't want that?” says Hurel.
"Rinsing with cold water will 'close' the pores on your scalp, which helps prevent dirt, grease and oil getting in. Plus, it can reduce hair shedding."

In other cases, thinning hair is triggered by something going on inside the body — for instance, a thyroid problem, a shift in hormones, a recent pregnancy, or an inflammatory condition. Hair loss may also be genetic. The most common genetic condition is known as female-pattern hair loss, or androgenic alopecia.
Hair can stop growing or grow slowly for a variety of reasons including age, genetics, hormones, or stress. You may notice your hair stops growing in one spot or seems to be growing slowly on one side. There are plenty of treatment options for slow-growing hair, including: medication.
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 immediately halts hair growth. As previously stated, our hair needs moisture (preferably soft water for your hair).
Dr. Zeichner explains that “rice water contains high starch levels, which coats the hair shaft to add strength.” Flowers agrees, adding that “rice water coats the hair strand, similar to protein, so it does have the ability to strengthen the hair shaft and thicken the hair.”

The bottom line. Knowing how to brush your hair the right way can help prevent breakage and damage. It can also keep your hair healthy, shiny, and free of tangles.

Most hair strands grow at an average rate of about 0.3 to 0.4 mm a day. So, this means it may grow up to one-tenth of an inch or a little more in a week. However, this growth differs with people. Genetics, hormones, nutrition, and stress levels all play a role when it comes to the health and growth of tresses.
