Ask the hair expert, Dr Shahid Shamsher……
After protein the largest constituent of hair is water. In fact water makes up about 25% of the total weight of every hair strand. And even for adequate hair-protein formation water is very much a required catalyst.
The amount of water that a person requires varies greatly. Exercising and outdoor activities of course require more water, but studies have shown that even people who are indoors most of the times are surprisingly dehydrated. This is because often people who work in such environment are heavy consumers of caffeinated products like coffee, tea, and aerated drinks. Caffeinated drinks actually force the water out of the body creating even a greater need for water consumption. So you can be indoor all day, drink 4 cups of coffee or tea and be as dehydrated as if outdoors. The worse part is the even with mild dehydration the hair loses water first.
The human body has a natural mechanism where any shortfall of water is compensated first from the hair and skin. Even with mild dehydration, circulation to the base of the outer skin, where the hair roots are located, may be shut down as a measure to prevent losing water through evaporation from the skin’s surface. Thus by the time you develop appreciable levels of thirst, your hair may already be dehydrated and damaged. Adding to this are procedures like ironing, hot air drying, coloring, which further reduce the moisture levels in the hair shaft.
In addition to hair becoming dry and brittle and breaking from in between, if you also have symptoms dryness and flaking of scalp, persistent dandruff etc, hair dehydration should be explored.
