Gray Hair Is Not Just Due To Age
The cause of gray hair is very complex, not simply age, but also other reasons. Here are some problems related to gray hair in the elderly have been verified by clinical studies.
The gray hair mechanism works like?
The mechanism behind graying hair can be summarized as follows: the amount of pigment or melamine in each hair follicle is monitored by a special stem cell called melanocyte. Each melanocyte is "programmed" to take over a function for a period of time after which it will age and die.
After melanocyte function, the hair follicles still develop, but due to lack of natural color should be white or maybe half white and half black that people are used to call "pepper salt" and when the hair is gone pigments, it will turn completely to silver stage euphoria
When do people wear gray hair?
According to a study published in the journal Discovery of Diseases (JID) of the United States recently, the group of white people is the group with the earliest gray hair, from the middle of the age of 30, there were gray hairs. Asians, Africans with gray hair later.
Not only older people may have graying hair, even young people may experience this condition
Overall, about half of the population in their 50s began to have gray hair, particularly in the genetic group, the function of the melanocytes was blocked, stopped earlier, so gray hair was earlier than healthy people
In general, gray hair often appears in the temples and the top of the head, so far this phenomenon is not well understood. In addition, the inner hair and hairline often fade faster than the rest.
What causes gray hair?
Although the phenomenon of gray hair contains many factors, but until now science has "points" some of the following reasons.
Due to illness: firstly, there is a genetic element called vitiligo (vitiligo), a form of albino, the culprit that makes gray hair in patches. Because malignant anemia is often caused by a lack of vitamin B12, it reduces the production of pigments for the hair color. Because the body lacks an important enzyme that breaks down peroxithydro, the resulting increase in this compound in hair and skin leads to premature graying.
In addition, due to a number of diseases such as Werner syndrome (old age disease), diseases related to the thyroid (hyperthyroidism, hypothyroidism)
Due to stress: According to a research of experts from Tokyo Medical University, Japan (TMDU) recently published, stress is the culprit causing very strong gray hair. That's why people have a general idea that only after one night is white hair to talk about the harmful effects of stress.
Stress, stress can cause your hair to gray quickly
Through experiments on mice experts at TMDU found that stress is the culprit for DNA damage, scientists call this phenomenon of diffuse alopecia areata (Diffuse alopecia areata) causing black hairs to fall out and non-pigmented hair (gray hair) is left intact.
Silver hair, hair loss after chemotherapy: People with cancer after chemotherapy often have hair loss, gray hair but then hair grows back again black.
This is a mystery so far science has not explained, it is only assumed that the pigment cells may have been reactivated and help it produce more pigmentation so the hair is black again. And this is also the mechanism currently being scientifically researched to prevent gray hair because of age in humans.
Can gray hair be treated?
Until now there is no cure for this disease, both traditional and modern. Currently, science is working on stem cell therapy to restore the original hair color, but this method is not simple, it takes time to verify.
While waiting for feasible therapies, there have been drugs on the market to help black hair back, but this method also has a downside, especially when using unqualified dyes.. . Dịch vụ: Thiết kế website, quảng cáo google, đăng ký website bộ công thương uy tín
