Last updated Sep 27, 2023

Everyone has the desire to have shiny, glossy hair since it is not only a symbol of beauty but also a marker of good health. Healthy hair has a natural shine, while damaged hair looks dull and lifeless. You may inadvertently notice that your hair is dull and wonder why it is dull. If you are looking for the cause of your dull hair, then you have come to the right place. In this article, we will tell you why your hair is becoming dull and how to prevent it from becoming dull.

What Is Dull Hair?


Dull hair means that it is lacking in moisture and natural shine. When your hair cuticles open up and separate because of damage, they are unevenly reflecting light, which can make your hair look dull. Some common signs of dull hair include dryness, frizz, and a coarse texture.

What Does Cause Your Hair Dull?

Would you like to know what causes your hair to dull? Here are the various causes of dull hair, you can have a look at them one by one.

1. Product build-up


Product build-up is one of the common reasons for dull hair. For the sake of making our hair look healthier or better, we usually use a variety of hair care or styling products. If we don't wash them out in time, residues from these products can build up on our hair and scalp over time. Ultimately, this build-up stops the natural hair oils our scalp produces from entering the hair shaft - resulting in dull, dry hair.

2. Frequency of hair washing


The frequency of washing your hair can have a direct effect on dullness. For most hair types, hair should not be washed every day. This is because when we get our hair wet, the inner layers of the hair swell, leading to an elevated cuticle and the release of moisture and protein. Over time, this can result in damaged hair. Damaged hair has a raised cuticle structure that does not reflect light and makes the hair look dull.

3. Hard water


Water residue is another common cause of dull hair. According to statistics, 85% of homes in the United States have some degree of hard water. Hard water is water that is high in minerals, usually calcium and magnesium. The positive cationic charge of these minerals causes them to bind to the hair, leaving our hair dull and shapeless.

If you find that your shampoo does not lather easily when you wash your hair, or if you find that your hair feels sticky and flaky afterward, this may indicate that you have a hard water build-up.

4. Extreme weather

It is well known that various environmental factors are also one of the reasons why your hair looks dull, especially the factors in the air. Prolonged exposure to the sun's UV rays, extremely dry air and strong winds can damage the outer protective layer of your hair, resulting in dry, dull hair. Additionally, pollutants in urban areas can build up on the hair, causing dull hair.

5. Excessive heat styling and hair dying


To follow a trend or change our style, we frequently do hot styling, for example, straightening our hair with a flat iron, curling our hair with a curling iron, etc. This damages the cuticle of our hair and makes our hair gloomy. In addition, we may change hair color frequently, when the cuticle of the hair is repeatedly opened and closed. When hair is bleached, it becomes more porous and does not reflect light, resulting in dull and lifeless hair.

How to Prevent Your Hair From Becoming Dull?

Therefore, we need to minimize the use of conditioners or styling products as much as possible to reduce product buildup on our scalp so that our hair can shine.
