In the first place, let’s focus on some basic information. The gray hairs develop from lack of pigment (melanin) in the hair follicles. Although the follicles still have a normal amount of melanocytes (cells that produce pigment) cells, these cells stop working with time and the hair becomes gray or white.
What is certain is that it is not very common that you go gray at an early age as the whitening of the hair follows the rule of 50/50, only 50% of the population start going gray before age 50 years.
However, that does not mean that young people are free from this occurrence. “Genetics plays an important role”, says Joshua Zeichner, a dermatologist in New York City. “If your mother or your father developed gray hair at an early age, probably you will too. And, of course, you can’t do anything about it.”Although there is no precedent in your family, you could also notice hair aging prematurely due to other factors, such as for example a deficiency of vitamin B12 or smoking.
Gray hair developing early could be related to the nutritional deficiency associated with smoking or other unhealthy lifestyle habits. It is also possible that the oxygen free radicals that are increased by smoking damage the hair follicles and cause the hair to become white prematurely.
As you may have already heard before, constant stress can make your hair whiten before its time.
Although there is no direct link, stress increases levels of cortisol, a hormone that increases the number of oxygen free radicals that can damage hair follicles and the cells that produce the pigment of the hair.
Unfortunately, it is impossible to restore the pigmentation of hair that has already lost the color. For that same reason, it is important to try to reduce the risk factors that are in our hand to keep things under control before all of the head becomes gray.
If you’ve done some adjustments in your lifestyle, and the gray hairs continue to appear, it is likely due to your genetics. In these cases, it is advisable to learn to love and include them in your look. Although you can always dye them, why hide something so natural?
