Scientists have found the root of the mystery of why our hair turns gray. A person's hair color is determined by the stem cells that create and store pigments in the skin. These pigments create the hair color of blondes, brunettes, and redheads. As we age, these pigments begin to die. The different look wouldn't happen so soon if the cells that produce the hair color didn't begin to spoil it, making it unusable, and leading to premature graying.
Studies have also been conducted on mice whose fur has turned gray. As a result, further research was conducted by examining the human scalp for a possible cause of premature greying. Unfortunately, no breakthroughs will reverse the graying of human hair. But there is an opportunity to better understand melanoma, a form of skin cancer that kills around 8,000 people a year.
Although not directly related, melanoma and gray hair fall into the same category. Pigment cells, or melanocytes, give hair a youthful color when they are working properly. When they die or develop in the wrong part of the hair follicle, gray hair inevitably develops. In addition, melanocytes can take a completely different path by multiplying uncontrollably to form malignant melanoma tumors.
Things everyone should know about why our hair turns gray:
* The biggest culprit of gray hair is the normal aging process. Just like the skin, the structure of our hair changes with age. Dermatologists have coined a phrase or rule that 50% of people will have about 50% gray hair by age 50.
*A person's ethnicity can affect whether or not they have gray hair. Researchers have yet to figure out why ethnicity determines the ranking:
1. Caucasian, with redheads in particular
2. Asians
3. African American
* Stress affects our skin and hair problems. Think of those people who went through chemotherapy, lost all their hair, and then it grew back a different color. Illness and stress play an important role in graying hair.
* Like everything else, our lifestyle can change. Certain low vitamin levels can be attributed to loss of hair pigment. Choosing foods high in certain vitamins, nutrients, and antioxidants can help protect cells from toxins, prevent cancer, heart disease, other illnesses, and yes, even gray hair.
* The myth that hair turns gray is just a myth. A single strand of hair grows for approximately 1 to 3 years before falling out. When the new one grows out, it will most likely be white, depending on your age. As the hair regenerates, it must again be freed of pigment-forming cells and eventually wears out.
