Ooh!
I can't believe that beauticians have absolutely forbidden words in the face of celebrities.
In Japan, the absolute prohibition of celebrities is "white hair", and both men, women and children are super concerned about the word "white hair".
So, what to do if you want to dye your hair white?
Simple, gesture with your fingers.
Yokoyama Hiroshi learned this trick from his predecessors when he went to a beauty salon to dye his hair.
Moreover, in Japan, not only do celebrities care about gray hair, but ordinary people also care super much.
Most of them are young and their hair is already gray and they need to go to a beauty salon to dye their hair.
Japan's hair coloring industry is therefore particularly popular.
A beauty salon that specializes in dyeing gray hair has even been on a Japanese variety show because of the price discount
Harm, I have to say that contemporary young people are not easy enough...
My hair was graying and my wallet wasn't full yet.
So, today the sheep came to seriously talk to the sisters about the fact that the white hair of The Port is too early, and incidentally also opened some rumors about the white hair.
Why does my hair turn gray?
I don't know if the sisters have found that the speed of graying of hair is not the same as the hair in the armpits, legs, and bikini area.
Most people, even if they are middle-aged, have white hair on their heads, and the hairs on their legs and armpits are still stubbornly growing, shining with a bright black luster.
The reason lies in the complex structure of the hair.
The structure of human hair can be divided into the epidermal layer (hair scales), the cortical layer and the medullary layer
According to the anatomical division, from the bottom up, it can be divided into four parts: hair papilla, hair follicle, hair root and hair shaft
Among them, the hair papilla is responsible for providing nutrients.
It provides enough nutrients for smooth synthesis of melanin granules.
If it is not nutritionally sufficient, the melanin particles will have a synthetic disorder and there is no way to go to the hair follicle and hair roots.
At this time, the cortical layer and medulla layer of the hair will also become white due to the reduction of melanin particles, resulting in gray hair
SO, sisters, don't wonder why some people have gray hair and look good.
The hair turns white mainly because the melanin particles are reduced, the epidermis layer (hair scales) is fine, there is no injury, so it does not affect the hair quality.
The sisters who don't understand yet look at the picture below
By the way, the sheep refute the rumor here: white hair will not pull out one long three!
The case of growing three roots is often because there is a problem with the hair follicles of your hair, and from the hair papillae, you lose the ability to deliver melanin.
Blame the hair follicles, not your own hands.
If there are one or two white hairs, pulling it out will not affect it, but if there are many roots, numb and tidy up, go to the doctor!
What is the difference between congenital whitehead and acquired whitehead?
Although the root cause of gray hair is the reduction of pigment particles, there are many reasons for the decrease of pigment particles.
Therefore, hair graying is divided into two categories: congenital and acquired.
1. Congenital gray hair
In general, congenital whiteheads are caused by genetic or congenital deficiencies, and are manifested as localized gray hair.
The hairline area in front of the head is the area of the hairline in front of the head
emmmm, so look, the hairline area is really high risk.
Hair loss falls first here, and whiteheads are also white here first.
Congenital whiteheads caused by family history genetics have little impact on physical health, and congenital whiteheads caused by congenital deficiencies can be supplemented by acquired nutrition.
Moreover, there is a saying that due to congenital deficiencies caused by white hair, the most common manifestation is still yellow color.
This is common in infants.
Baby hair is yellow in the early stages of growth because of low pigment, but under the reflection of light, it will be a little white
Therefore, mothers should not be too flustered when they see that their children's hair is a little white.
If it is hereditary gray hair, it usually appears in adolescence, not in infancy.
If there is no family genetic history, it is still possible to raise black.
2. Acquired gray hair
The causes of acquired gray hair are complex.
Mental stress, upside down day and night, insufficient sun time, insufficient intake of nutrients and endocrine disorders and other reasons can lead to acquired whiteheads.
In general, acquired gray hair can be divided into two types: nutritional deficiencies and diseases.
This kind of acquired white head is often not like in film and television dramas, all white at once, making it look like doing modeling.
Its white head is no region, it can be said that it is wanton, and it looks at where the white is.
Therefore, the visual effect is not beautiful, and it looks particularly like it is not old before aging.
Not as white as natural whiteness when you are older
Once again, I regret Lan Jieying, her white hair due to mental pressure also belongs to the acquired whitehead
Due to the lack of nutrients caused by the acquired whitehead, the high probability is the lack of micronutrients such as cobalt, copper, and iron.
The absence of these micronutrients weakens the ability of melanocytes to synthesize melanin.
This causes melanin to produce synthetic barriers in the hair papilla of the hair, unable to deliver pigment particles to the cortex and medulla layer of the hair.
Thus, it causes the hair to turn white.
This is recommended to go to a doctor to prescribe medicine.
In general, it is ok to complete the missing trace elements.
Due to the acquired whitehead caused by the disease, it is necessary to analyze the specific problem.
For example, a sister with a problem with the thyroid gland is most likely caused by a decrease in the ability of pigment cells to produce pigment particles
Patients with encephalitis and neurologic lesions are mostly due to impaired papillary passages in hair.
But albinism and vitiligo are affected by generalized pigmentation
The good news is that these gray hairs caused by acquired reasons can be improved by therapeutic means.
The bad news is that if you are due to mental stress, day and night upside down caused by the day and night whitehead, unless you completely change your schedule, you will still relapse after treatment.
How to delay the graying of hair?
Sheep at the beginning also harbored, the essence of hair whitening is a reduction in pigment particles.
No matter which race, as long as there are fewer pigment particles, it will turn white.
Blonde people in Europe and the United States are more prone to 4 points of gold, 4 points of brown, and 2 points of white because of pigment particles
From a medical point of view, under normal circumstances, normal people from the age of 35, the pigment cell function of hair begins to decline, and the pigment particles will be reduced accordingly.
When the pigment cells of the hair decay to the point where they cannot produce pigment particles, gray hair also appears.
However, now everyone is generally under pressure, so this time is also moving forward.
However, long white hair is not impossible to delay!
1. Intake of sufficient nutrients;
Experiments have proved that if black rats have been eating foods that lack folic acid, pantothenic acid, vitamins, etc., the rat hair will become gray and white.
Therefore, sisters must consume enough nutrients and order less takeaway.
Long-term lack of vitamins B1, B2, B6, niacin and other foods, hair drops quickly turn white.
2. Reduce the number of hair coloring;
Previously, the United States had tested 169 permanent hair dyes sold on the market and found that 150 (89%) of them had carcinogenic effects.
Hair dyes that are prone to carcinogene act directly on the hair, which can easily cause misalignment of pigment particles.
That is to say, although the hairball part of the hair has formed melanin particles, it cannot be transported.
This kind of hair can easily cause black roots and white tails.
3, there is a disease to treat, do not delay;
Most people's whiteheads are due to acquired reasons, and the formation of acquired whiteheads is related to many diseases.
Depression can lead to whiteheads because poor psychiatric factors cause spasms of the angiogenesis that supplies hair nutrition, resulting in dysfunction of melanin secretion by pigment cells in the hair papillae and hair bulbs.
Caries and tonsillitis can also stimulate the hair papillae and hairballs of the head due to bacterial action and nerve reflexes, affecting their normal work.
Our bodies move our whole body. Therefore, everyone who has a disease should not drag, dragging and dragging may become multiple diseases.
Moreover, babies should remember to stay up less late, bask in the sun more, and keep a happy mood, which will delay the aging of pigment cells.
The only one who stays up late in retaliation hurts you.
