Why do I have gray hair?

White hair, a symbol of middle age and now life's ups and downs. Seeing your parents' hair turn white shows that time has passed this much. But why on earth do gray hair fly?

 

White hair and gray hair are different?

 

White hair is a normal phenomenon with age. The color of hair is determined by melanin cells in the hair follicles. Cells synthesize melanin pigments, and the higher the amount of pigment, the darker the hair color. The reason why hair turns white as you get older is because the number of melanin cells that synthesize melanin decreases and its function decreases.

 

Westerners are known to begin to develop in their mid-30s, Asians in their late 30s and Africans in their late 40s. White hair comes in order of side hair, top of head, and back of head, followed by mustache, beard and eyebrows. On the other hand, the color of hair on the armpit or chest rarely changes.

 

In young people, gray hair is often called 'saechi,' which is a common name and is medically synonymous with gray hair. However, even if it is not aging, there are many causes of gray hair. Hormone abnormalities such as hyperthyroidism and degradation can also be caused, and many studies show that diseases such as malignant anemia, osteoporosis, diabetes and kidney disease cause gray hair.

 

Family history also affects. If you have gray hair at an early age, it is highly likely that one of your parents has the same experience. However, if you have gray hair at an early age, it is recommended that you see a specialist because it is likely to be related to a particular disease.

 

In addition, the phenomenon of partial gray hair unlike gray hair is called white hair, which can be caused by symptoms such as Vardenburg syndrome, partial whiteness, T-body syndrome, Alessandrini syndrome, neurofibromatosis and nodular sclerosis.

White hair, you can get stressed out?

 

Stress can also be a cause. No direct link and mechanism has been revealed that stress causes gray hair. Stress, however, causes a blood circulation disorder and constrains the blood vessels of the roots that nourish the hair by secreting the hormone adrenaline. Then, will he return to black hair after solving the cause of stress? Sadly, the probability of having gray hair once is very low.

 

The more gray hair you pull out, the more you get?

 

When people don't want to see gray hair, they often pull out hair that stands out. Whenever that happens, some people tell them not to pull out their gray hair, saying, "The more they pull out, the more they get." Is it true? That's wrong. White hair grows again only as much as it is pulled out. Since only one hair comes out of one hair follicle, pulling one does not produce two to three gray hairs on the spot. It is possible to get gray hair again because the roots remain under the scalp even if you pull out your gray hair.

 

Dyeing is bad for your health?

 

Then there is only one way, dyeing. However, dyeing can cause dizziness, tinnitus, or hair loss. The derivatives of aniline pigment contained in the dye (the chemicals that transformed aniline into a parent) have a high skin absorption rate and are characterized by poor emissions.

 

Frequent dyeing can lead to hair loss because dye damages hair through pores. For this reason, dyeing is a taboo for people with hair loss, even if they have gray hair. Experts advised, "It's better not to dye your hair as much as possible, but if you have to, it's better to make sure that the dye doesn't touch your scalp directly."

 

Despite the circumstances, there is no cure for gray hair. Even if you can't help gray hair that grows over time, the only way to keep it from getting gray hair at a young age is to keep it from happening. It is best to facilitate blood circulation through scalp massages and to ensure that enough nutrients can be transferred to the roots through regular exercise, sufficient sleep and rest.
