For many people, white hair is a difficult imperfection to accept. Many resort to reflective dyes or shampoos to cover up graying hair. But it is important to understand when the first gray hairs begin to appear to assess whether this effect is the consequence of a more serious disease.
Beyond a certain age almost everyone, except the luckiest, has hair whitening, but in some subjects the appearance of the first white locks is decidedly premature and therefore requires a diagnostic study.
The color of our hair it depends on the pigmentation of the hair follicle which is found at the base of each hair. Inside the bulb are melanin-rich cells responsible for hair coloring. A high concentration will be responsible for a darker color and conversely a low concentration of melanin will produce hair tending towards blond.
Pay attention to the appearance of the first gray hairs
With the passing of the agesin the hair follicles melanin cells begin to fail until completely exhausted. Following the total loss of this pigment, the hair loses its color and remains permanently white.
This process, if it occurs in the right period of life, should absolutely not alarm because it is absolutely predictable by human physiology. But if the problem occurs at a young age, it would be good to investigate further.
It is also true that in most cases, the trigger is genetics against which nothing can be done. But one of the causes that lead to the early appearance of white hair is the high level of stress that leads to the loss of stem cells present inside the bulb.
Thyroid dysfunction among the possible causes of hair whitening
Another the possible cause should be reported to smoking which by creating oxidative stress in our body, destroys melanin cells. The production of this pigment can also be countered by a dysfunction of the thyroid gland. Indeed, a recent study showed that People with hypothyroidism can in most cases show gray hair already at a young age.
Ultimately, scalp whitening can be triggered by a deficiency of an important vitamin, B12, which plays a key role in red blood cell synthesis. Its absence in the body causes a weakening of the blood and therefore a decrease in the transport of oxygen throughout our body and therefore also to the hair follicle. In this case, the bulb will not be able to obtain a sufficient amount of melatonin to color the hair.
Obviously, also pay attention to pollution and poor diet which, creating imbalances within our body, are very often the cause of this unpleasant “problem”.
