Since I came to the United States, I lost a lot of hair every time I took a shower. It worried me for a long time. I thought there might be some correlation between the quality of the water and hair loss. The water we use to take a shower in the United States is hard water, and the water we use in my hometown is soft water. Hard water is “water that contains magnesium, calcium, or iron salts and therefore forms a soap lather with difficulty.” Soft water is “natural or treated water that does not contain a significant amount of dissolved minerals such as compounds of calcium or magnesium.” Some people, like me, believe that hard water directly cause hair loss. However, some other people, even some scientists consider that there are no evidence to prove that hard water can cause hair loss.
As mentioned above, hard water contains mineral contents. I have tried to find some research about whether hard water can actually cause hair loss. It seemed that people just believe hard water is harmful without valid evidence. The research indicated that “Because of its large mineral composition, hard water could make the hair appear dull and make the strands wear out. When the hair ruptures near the scalp, it may look like your hair is receding at an accelerated rate.” Because of the negative aspects of hard water, people tend to believe that hard water can cause hair loss. Other hypothesis had been rejected before any research. Many experts had said that it is still uncertain.
Here are two experts discussing their opinions about hair loss. They both insist that there are no evidence prove that hard water can cause hair loss or hair breakage. However, they think that the minerals in hard water make our hair feel different. It is probably that what we feel different makes us believe that hair loss is due to hard water.
Hard water might or might not cause hair loss. It is still a problem that need to be study in the future. We cannot control the water quality we use when we wash hair. It would be better to go to the doctor and ask the real reasons of hair loss.
