White hair develop when the melanin that is responsible for hair colour gets shed off the hair follicles. It can also be out of genes if your hair is beginning to turn white at a young age, or due to some ailment.
Is White Hair Normal?
Contrary to the general population belief that your hair does not grow once you have reached adulthood; there is evidence that it does and it also changes color. Perhaps you were once a young man or lady with scalp with full bony brown, black, red or blonde hair. Now that you’ve grown older, some sections of your head might become less covered with hair, or you hair may have turned grey or white from before.
This is the part of skin where you see tiny holes; that is called hair follicles which are small sacs that are lined with skin layers. The organ in particular has melanin pigment cells known as hairs that are rooted in hair follicles. These cells determine the color of hair that grows in your head. However, years and months go by and natural hair also receives some damage and hair follicles are no longer able to produce pigment hence white hair is produced.
What causes white hair at a young age?
In particular, individuals with dark hair contrast with white heads of hair most significantly than anything else. While the gray hairs may be associated with the older generation, it is not unusual for a person to start comprehending or getting strands that are colorless entirely while being in high school or college. For instance for those who are a teenager, young adult in their 20s, they may develop one or more than strands of white hair.
And although there may be some ways on how the pigmentation can be regained, such possibility will drastically depend on the root cause of the problem. These are main factors that tell on early graying of hair.
1. Genetics
Time and again, it truly was your makeup that schedule when or whether you turn out the white hair. By evaluating and comparing the pathology of white hair color emergence, one can highlight that such a phenomenon runs in families: if at the first sign of gray or white hair, both parents and grandparents can be attributed to this category.
You can’t change genetics. But if you do not feel like you like how it looks like if you have gray hair, there is a way out you can dye your hair.
2. Stress

These conditions also reach the hair; stress is among the factors that exert pressure on hair follicles. A 2013 study carried out observed that reduced stress and resulting in wasting of stem cells in the hair follicles in mice. Thus, if you have woken up one day to find a liberate of white hair, it is possible that stress was the cause. This theory may also account for why some presidents – or other heads of state – might look older or turn grey faster while in office.
3. Autoimmune disease
It is also important to know that an autoimmune disease can also lead to premature whitening of hair. This refers to the condition when the body’s defenses target and destroy its own cells and tissues. It is common to observe an attack on hair in alopecia and loss of pigment in vitiligo through an immune system response.
4. Thyroid disorder
It is also believed that fluctuation in hormone levels due to thyroid disorders, for instance, hyperthyroidism and hypothyroidism have to do with early onset of white hair. The thyroid is a gland that appearances like a butterfly and it is situated in the front of the neck, right below the chin area. This way it is capable of regulating many functions on the human body for example metabolism. Besides, based on the findings it shows that, the condition of your thyroid affects the color of your hair. One of the factors that will make your body produce little or no melanin is through hyperthyroidism or hypothyroidism.
5. Vitamin B-12 deficiency
Early sign of leaving the hair white may also be as a result of a deficiency in vitamin B-12. In fact this vitamin is very important for you and your body. It provides energy, it strengthens hair and contributes to the hair colour.
The lack of vitamin B-12 is directly linked to a disease known as pernicious anemia, which is a condition defined by your body’s inability to digest this vitamin. Your body requires a vitamin that is known as B12 for producing red blood cells, cells that are charged with the tasks of transporting oxygen to cells in your body including the hair cells. The deficiency can lead to the reduction in hair cells proliferation and decrease in melanin synthesis.
6. Smoking
Smoking is another vice that can cause premature white hair; people who smoke genetically have a tendency to develop white hair early than the others. The research with 107 subjects proved that there exists a relationship between “the beginning of hair’s aging before the age of 30 and smoking,
Ever since smoking cigarettes commenced, the world realized that it posed a serious threat to lung cancer and heart diseases. While the short term consequences are mostly central nervous system and heart/ lung disorders, long term can extend to hair. Tobacco from cigarettes tightens blood vessels, which, in turn, may decrease the circulation of blood to hair roots and lead to balding. Thirdly, it is a fact that numerous chemicals within cigarette can adversely affect almost all organs within your body; even your hair roots that cause early white hair.
This question begs a very important query: Is it possible to prevent the onset of white hair?
In some instances, it may be possible to reverse or prevent white hair completely depending on the cause of the discoloration. If the cause has to do with heredity in most cases, there is no way to avoid such insults or to fix them for good as far as their effect on the color of the skin is regarded.
That is, if someone has an illness, then it is always advisable to visit a doctor and then check if he or she has developed white hair due to an ailment. Sometimes diseases causing pigmentation to become darker can be treated, and in most occasions pigmentation may return.
One research shows an area to turn white due to a thyroid problem might revert its color once cured, this after a hormone therapy. Supplementing with B-12 injections or Medrol, that was prescribed to treat a deficiency, can also significantly benefit the health of hair follicles and return your hair to its natural color. There is no proof that they are capable of regrowing it if the white hair resulted from stress or smoking, for instance regrowing hair after stopping smoking or cutting stress.
