Today, when adults are fishing, I just saw the news that Son Ye-jin announced her pregnancy on her personal social account. Before I could chat more with my colleagues, more than 400,000 likes and blessings popped up as soon as I turned around.

Son Ye Jin and Hyun Bin This magical couple has really attracted the attention of everyone since their every move.

When adults are fishing today, I just came across the news that Son Ye-jin announced her pregnancy on her personal social account.

didn't wait to chat with colleagues for a few more words, and as soon as he turned around, more than 400,000 likes and blessings were refreshed.

Hey guys, it’s broad daylight, is everyone working at Ins?

is nothing but u1s1, I have to admire the eyes of netizens.

Adults remember that in May, when Ye Jin posted a honeymoon selfie on Instagram, some netizens pointed out that Sun Xian in the photo looked pregnant.

Some people even directly asserted that bb is at least 5 months old.

It’s just that the agency’s denial came too quickly, and netizens could only continue to wait and see.

But as Sun Xian said himself, the reason for not announcing it early may be because the pregnancy was earlier, so he was more cautious.

Most netizens understood and expressed their blessings, saying that this is probably the most beautiful form of love.

even used a line from their romance drama "'s Crash Landing on You ": I also want to see you grow gray hair, wrinkle your face, and look older.

But having said that, it is romantic to grow old with the person you love deeply. But what will happen if we grow gray hair at a young age? !

not only looks old, but also shows vicissitudes of life.

For example, Jin Minxi, who just went to Berlin to participate in an event a while ago, with a head of white hair visible to the naked eye and a plain gown, was directly called a nun by netizens.

In other words, why did have gray hair early even though he is not very young? Is there any way to save gray hair? ! How come

is so bald and old?

The color of our hair is mainly determined by melanocytes in the hair follicles.

The more melanin particles in the hair and the greater the density, the darker the hair color will be, and conversely, the lighter the hair color will be.

Under normal circumstances, the capillaries in the hair follicles are responsible for providing sufficient nutrients to the hair papilla and hair bulbs, so that they can synthesize new melanin particles diligently every day.

But if any link in the formation of melanin is affected, for example, tyrosinase died in the first episode due to loss of activity, then naturally the melanin will not be able to survive until the day it returns to the palace.

This is also the most common reason for gray hair in the elderly.

However, some students may want to ask.

I’m still young, and I still have decades to pay for my mortgage. Now my hair is gray, is that “less gray hair”?

emmm… Some studies have shown that baldness is most likely due to genetic influences.

50.4%-76.7% of people who have whiteheads have a family history, and there is no significant difference in the incidence rate between men and women.

But don’t rush to rely on your parents. Among different races, researchers have a relatively clear definition of this "young" age.

Generally speaking, white hair appears before the age of 20 for Caucasians, around 25 for Asians, and before 30 for Africans.

In other words, we Chinese can only be genetically selected as "the chosen ones" if they have gray hair before the age of 25.

html People who suddenly have gray hair after the age of 125 have to find their own reasons.

# Everywhere pressure

Have students ever experienced the situation of "your hair was full of white when you were in high school, but after playing in college for a few years, your hair is getting darker and darker"?

Or have you ever felt that since you went to a not-so-pleasant company, your gray hairs are getting more and more like bad things?

That’s right!

According to research, when the mind is overly stressed, long-term unhappy, pessimistic and depressed, or mentally stimulated and traumatized, it will increase the oxidative stress of the hair, leading to the direct death of melanocytes .

After researchers injected experimental mice with toxins that can cause severe pain and cause them to produce strong mental stress, the hair of the experimental mice quickly turned white.

And when the researchers cut off the adrenal gland , the source of stress transmission in the mice, the new hair of the mice was as thick and black as before.

Therefore, for 24-hour online workers, the ubiquitous life and work pressure may be a major reason why our heads are becoming increasingly bald.

# lack of vitamin D

The trace element content in hair can objectively reflect the distribution and metabolism of trace elements in the human body.

Therefore, students who have gray hair due to non-genetic reasons or natural aging can basically find deficiencies of multiple trace elements at the same time as long as they go to the hospital for examination.

For example, when the body lacks trace elements such as vitamin D, iron, phosphorus, zinc, copper, etc., it will be difficult to secrete tyrosinase, an essential substance for melanin synthesis.

Especially lack of vitamin D will not only greatly affect the body's absorption of zinc, iron, copper and other trace elements, will also lead to premature gray hair.

It is also an important reason why many migrant workers become bald at an early age.

A survey in East my country in 2019 showed that even in the sunny summer, 83.7% of the respondents were still vitamin D deficient.

If you happen to have the habit of excessive sun protection and drinking fat home water daily, it will be even more...

# Other diseases

Although it is not absolute, if the body has symptoms such as albinism. Pernicious anemia, hyperthyroidism, metabolic diseases , etc., may cause large and rapid changes in hair color.

So, if suddenly there is no pressure for a certain period of time, but your hair suddenly becomes a lot whiter.

Don't hesitate, Ma Liu'er goes to check up.

# Ultraviolet damage

The latest research shows that gray hair is closely related to damage to melanin stem cells.

When melanin stem cells are damaged by ultraviolet rays or radiation and cannot continue to differentiate into melanocytes, the hair will gradually turn white due to lack of pigment.

In other words, if you tan your scalp too much, the melanin stem cells in your hair will be destroyed. Can

also make white hair black?

It's a bit sad to say that it is more difficult to make gray hair black again than to make bald hair bloom. (a little exaggerated metaphor

How difficult is it? Let’s put it this way, industry giant L’Oreal announced in 2011 that it would develop a pill to treat gray hair.

The result is now 2022, what I said Just like youth, the bird never comes back.

However, although there is no specific medicine that can completely turn gray hair into black, it is better to prevent it.

# Be a flat salted fish

A latest study published in "eLife" in June last year showed that

when the stress level in the body becomes high, the hair begins to turn gray, and when the stress level decreases, gray hair regenerates. The hair can be reversed.

In other words, work really makes people grow old, so it is true that they lie flat and rotten!

For example, no matter how busy you are at work, you must remember to give yourself some (touch fish relax time, scold with your sisters) Swear at the boss and relieve stress.

Or, don’t set 800 alarm clocks to keep restarting in bed, and try to reduce the self-imposed pressure of getting up and the stimulation of alarm clocks.

Don’t let the pressure go, and reduce it in every aspect of your life. Negatives can always add up, and returning to black hair is not a dream.

# Don’t be picky about food, and don’t use excessive sun protection!

Vitamins interact with each other to absorb and utilize each other. In many cases, there is no way to lack anything. Make up for something.

Therefore, we need to pick more things that run on the ground, swim in water, and grow in the soil to make up for them completely.

In addition, in the production and creation of vitamin D by our body, 80% to 90% of the sources come from the joint participation of skin + ultraviolet rays + cholesterol .

Only a small amount of VD is left as a supplement from daily food.

Therefore, as long as we are not allergic to ultraviolet rays, we don’t need to be so afraid of the sun.

You can still show your arms appropriately when commuting, picking up takeaways, picking up express delivery, and daily walks.

At least he doesn’t dress like a beekeeper just to avoid the light.

# Try external lotion

This article is only visible to students who are young, gray-haired, desperate, and rich.

As you said before, there is no specific medicine that can completely turn white hair into black.

However, active substances that are already on the market and clinically proven to be effective in reversing gray hair still exist.

such as palmitoyl tetrapeptide-20, red formononeta root extract, strigose oat seed extract, acetyl tyrosine, dihydroquercetin glucoside, etc.

Theoretically speaking, the two ingredients in bold are considered to be the most comprehensive and most capable of solving fundamental problems among the ingredients on the market.

Although judging from clinical data, the average reduction of gray hair of subjects by 17% is not as powerful as it seems theoretically.

But the subjects with the most obvious effect reduced their gray hair by 56%.

Although there may be individual differences, the overall effect is gratifying.

At least for students who are troubled by gray hair and bulging wallets, the future is still promising.

Interested students can check it out on their own. I won’t introduce it here.

OK, let’s stop talking about the topic of white hair today.
