Using color to change how your hair looks is something that is been done for centuries by people from all over the world. Thanks to developments and cosmetic manufacturing in chemistry, the products and range of hair colors that are available today is big. In fact, many people go to school to learn how to get here a certain color or tone consistently.
You can change the color of your hair using many different methods for hair dyeing. There are several chemical processes used, such as neutralizing, tinting, and bleaching, that act alongside the natural pigments in the hair to change the color. There are many reasons people decide to use dyeing products to change the color of their hair. There are also many reasons your hair changes color throughout your lifetime. Some of those include:
- Aging: as you get older, the pigment production of your hair changes. Our hair stops producing melanin, so any new hair growth no longer has the pigment, which is why they grow out white. When you mix white hair with other hair that still has some color, it gives you a grey look, also sometimes referred to as salt and pepper.
- Blonde children: many children are born with blonde hair. Their hair can begin darkening as they get older, though, around seven or eight. This is because the melanin production increases as they get older, often causing them to have darker hair as adults.
- Factors in the environment: pigments in the hair can be impacted as the oxygen in the air attacks it. The weakest pigment is blue pigments, so they are the first to disappear. This leaves the hair showing through some warm undertones. The more wind and humidity you are in, the more oxygen that flows through your hair. The sunlight can also accelerate the process. This is why your hair is noticeably lighter after you have spent time at the beach. Spending time in a luxury limo can have the same effect because of the extra pollutants.
- Health: issues with your health can contribute to graying prematurely, such as having an autoimmune thyroid disease.
- Medications: some medications can alter the natural coloring of your hair. Several malaria drugs can make your hair lighter, while your hair may darken from drugs for epilepsy.
- Pregnancy: when you are pregnant, you have higher levels of progesterone and estrogen that can cause your lighter hair to be darker.
As you can see, there are many things that can cause your hair to naturally change colors. Often times, people will resort to having their hair colored chemically to get it back to its original color.
