When you get older and have more white hair, you will look even older. Most elderly people will choose to dye their hair to make themselves younger. Frequent dyeing of hair will have a certain impact on hair quality, and it will also bring some stimulation to the scalp. So be sure to pay attention to the following eight points!
1, don't wash your hair two days before dyeing your hair, so that the grease on your scalp can play a certain protective and isolating role when dyeing your hair. Even if it sticks to the scalp, it is easy to clean. This is especially important for people who often dye their hair.
2. When dyeing hair, it is best to choose the makeup dyeing method, and only dye the white hair, so as not to affect the overall hair quality. Because the hair below is dyed before, it doesn't need hair dye. If you dye your hair on your head every time, the damage to the hair below will become more and more serious.
3. Wash your hair every 48 hours after dyeing, so that the color will be more stable and you can avoid fading. Especially when dyeing your hair at home, you must pay attention to this. Because it is difficult to cover the white hair, frequent shampooing during this period will lead to white hair exposure.
4, the choice of hair dye is also very important, we must choose good quality hair dye products. Don't be greedy for cheap use of some high-quality and cheap products or fake and shoddy hair dyeing products. Because these low-grade hair dyeing products may do great harm to hair and body.
5, before the end of hair dyeing, don't rush to wash your hair, spray some warm water on the scalp, first rub the whole scalp with your hands, so that you can better decompose the hair dye stuck to the scalp, and it will be easier to clean when cleaning.
6. Dyeing your hair often will dry up because of lack of water. It is recommended to use shampoo and conditioner without silicone oil when shampooing. If possible, doing hair mask care once a week will play a very good role in hair maintenance.
7. Don't dye your hair too often. People with too much white hair can have their hair roots mended once a month. People with less white hair are separated by two to three months, or longer. Too high dyeing frequency has great influence on hair and skin.
8. You can choose some color hair dyes with good effect of covering white hair. This will not only make you look young, but also make your hair look more foreign. Colors that are too black will look older. Because individual dyed black may contain some metal components, which is more harmful to the body.
I hope that the elderly who often dye their hair will pay attention to the above eight points. The longer the interval and frequency of hair dyeing, the less the better. Don't dye your hair, it's best not to dye your hair. It is a normal physiological phenomenon to have white hair when you are old. You just need to trim your hair neatly without looking too old.
Many people have reached middle age, and their temples have begun to turn gray. Therefore, dyeing hair is loved by many middle-aged and old friends. However, improper hair dyeing can also cause harm to the body, and cases of hair dye allergy in life are not uncommon. So, should the elderly dye their hair? What are the hazards of dyeing hair?
Dyeing hair can induce diseases such as cancer.
Studies have shown that dyeing hair will increase the probability of women suffering from leukemia and lymphoma. Many middle-aged and elderly leukemia patients have a history of dyeing their hair. At the same time, hair dye will reduce the weight of uterus and cause harm to reproductive organs, especially black hair dye, which is even more harmful!
Commonly used dyes, such as azo and nitro, contain many kinds of heavy metal elements harmful to human body, which are carcinogenic to varying degrees and can also cause many diseases such as blood diseases. Because when dyeing hair, the dye will be applied to the hair for a long time, and it will enter the skin through the scalp and penetrate into the blood. In the long run, it will induce diseases such as cancer.
In addition, even though most hair dyes say "people with skin allergies" should be used with caution, there is hardly any package detailing the scope of "people who are not suitable for hair dyeing", and hairdressers in hair salons rarely remind customers.
But even if the harm of dyeing hair is so much, it can't stop the old people from dyeing their hair!
Because, the hair is white, how can it not be dyed?
Expert reminder
1, the dyeing time should not be too long and too dense, at most twice a year.
2. Check the scalp before dyeing your hair. If there are scars, dermatitis, etc. It is best not to dye your hair.
3. Patients with hypertension and heart disease and pregnant and puerperal women should not dye their hair.
4. Try to choose high-brand hair dyes and hair salons when dyeing hair, and wear protective tools. It is best not to dye your hair for more than half an hour, and clean up the residual hair dye in time.
5. Wash the scalp and hair thoroughly with plenty of water after dyeing, but don't scratch hard, and don't use too hot water and irritating shampoo.
6. People who are allergic after dyeing their hair for the first time must see a doctor in time, and don't dye their hair again in the future, especially those who are allergic, because each allergy will get worse.
Tip 1, dye your hair carefully in hot weather.
In hot weather, we sweat a lot, so our sweat glands and sebaceous glands are always in a state of intense work, and the chances of external stimuli entering the skin will increase. At this time, the harmful components in the hair dye are more easily absorbed by the human body through the skin. In addition, a large number of metabolites in sweat may make allergic and inflamed skin more serious.
It's better for the elderly to dye their hair less.
Many old people dye their hair in order to dye their white hair black, but their hair will grow quickly, so the number of times they dye their hair will be very frequent. Moreover, the hair dye of the elderly should start from the hair roots, so the hair dye will be in close contact with the scalp, which is more likely to cause harm to the body, so it is best for the elderly to dye less.
These people shouldn't dye their hair.
People who are allergic to drugs, paints, food, pollen, etc. And people suffering from asthma, urticaria, heart disease, hypertension and other diseases or recovering from illness should not dye their hair.
Many people have dyed their hair, regardless of gender or age. What's the difference between young people and old people? In fact, young people are more resistant to chemicals, while old people are less resistant. As far as the current chemical industry is concerned, a slightly better hair dye will not have a great impact on health, but how to prevent it if it is too frequent, just in case;
1. People who often dye and bleach their hair must be isolated before dyeing their hair. The so-called isolation before dyeing means that the scalp isolation milk is evenly applied to the scalp before dyeing the hair. Even the worst isolated milk will have a certain isolation effect.
2. Try to use high-quality hair dye and carefully check whether it is genuine. There must be a difference between genuine and inferior. Check the manufacturer's information and carefully check whether the font is clear and whether there is a certificate and production license.
3. Check the product composition, mainly to see whether there is "p-phenylenediamine". If there is, use it as little as possible, because this is the biggest impact.
4. Do deep cleaning after dyeing.
5. don't go to the supermarket to buy hair dye and dye it yourself ... the product quality of daily chemical line is not as high as that of professional line.
6. Don't dye your hair with nail pollen. Check the reason.
Old people often dye their hair, which is a very common phenomenon, mainly because white hair grows out, and when they get older, their image is not as beautiful as when they were young. If they have white hair, they will definitely look older and their mental state is not very full. This is because white hair and black hair alternate with each other, which leads to the phenomenon.
Everyone has to dye their hair. In fact, they all want to stop dyeing their hair, but it is difficult to do so in reality. I can understand everyone's feelings, because I used to be a hair stylist and often met older people to dye their hair. Both uncles and aunts like to chat with them. On the one hand, I can use my professional skills to improve my image temperament. On the other hand, I can learn a lot from chatting with old people.
Now I'd like to share with you some problems that the elderly should pay attention to when dyeing their hair. Come and have a look with me.
1. It is necessary to dye your hair regularly regardless of the length of your hair.
I believe that everyone will have such a situation-dyeing hair at home is to see where there is white hair on your head and apply hair dye casually. In fact, this is not very good, because dyeing hair is harmful to hair, and self-smearing is not the same. It will increase the difficulty of perm in the future.
Dye your hair regularly, that is, at the same time. For example, some people dye it once a month, while others dye it once every two months. Because the length of hair is the same, the position of dyeing color is the same, which can ensure that the frequency and length of dyeing hair are the same, whether it is a single replacement root or ordinary dyeing.
2. Choose a good hair dye.
One of the reasons why people dare not dye their hair often is that they have concerns about the quality of the hair dye, because there is always a feeling that there will be chemical residues on the scalp when applied directly to the head. This is entirely what they think. Technically, regular hair dyes are hard to do harm to human body, but it is better to choose some big brands for hair dyes. After all, the quality is guaranteed and the problem will be solved after sale.
3. Precautions before dyeing hair.
You can't wash your hair two days before dyeing your hair. The main problem is that some people are sensitive to the dioxygen emulsion of hair dye, and their scalp tingles every time they dye their hair. Therefore, if you don't wash your hair for two days, you can let the oil naturally secreted by the scalp build a protective film on the scalp and slow down the stimulation of hydrogen peroxide on the scalp. This is very effective.
4. Dye your hair and choose the right color.
Since dyeing your hair is to cover your white hair, you must choose your favorite color. The basic colors are burgundy, dark brown and black. Because older people like to keep a low profile, the colors they make are all dark, which is also in line with everyone's aesthetics. For example, these three colors are the most basic and can best cover your white hair. If there is no white hair, it is not recommended to dye it in light color, which looks more ostentatious and does not conform to the image.
Many old people often dye their hair in order to make their white hair black. It is more dangerous for old people to dye their hair than young people!
This is because the hair dye of the elderly should start from the hair roots, and the hair dye is in close contact with the scalp. In addition, the time interval for the elderly to dye their hair is often very short, and the hair dye is repeatedly absorbed by the head skin. If the constitution is poor, it is more likely to cause harm to the body.
So it is best for the elderly not to dye their hair. If there are special circumstances, they must dye it no more than twice a year. It is best to use natural pure plant hair dye, but this kind of hair dye is rare in the market and the fixation effect is not good; Go to a professional hair salon to dye your hair and have a skin test before dyeing it; Choose a semi-permanent stain.
1. Be sure to have a skin test before dyeing your hair.
Whether you are self-help dyeing your hair or going to a hairdressing salon to ask someone to dye your hair, you must have a skin test 3 hours before dyeing your hair. The method is to drop two dyes, A and B, on the same point on the inside of the wrist and wait for natural drying. If redness, itching, etc. occur during this process, the product can no longer be used.
2. Apply lotion before dyeing your hair
Before dyeing your hair, you should apply lotion on the hairline and behind your ears to prevent the hair dye from polluting and damaging your skin.
Don't dye your hair if your skin is scratched.
Remember not to wash your hair before dyeing it. First, the oil secreted by the scalp has a protective effect on the scalp. Second, you can avoid accidental scratches when washing your hair. If there is a wound on the scalp and then comes into contact with hair dye, it is easy to cause inflammation.
Don't dye your hair repeatedly within 4.3 months.
People who have dyed their hair within 3 months had better not dye it again. Because the hair dye contains a decoloring agent, this ingredient is harmful to the hair scales, and the damaged hair scales will become fragile and easily broken. If you dye your hair repeatedly within 3 months, the damaged hair scales will be damaged again and cannot be recovered. As time goes on, the health of hair is worrying.
Nowadays, dyeing hair has become a fashion. Oriental hair is originally black, and the ancients called it moss. Yellow skin, black hair and black eyes are also beautiful. But young people nowadays dye their black hair yellow, but their eyes are not blue. From the Chinese aesthetic point of view, this hair color is an unhealthy hair color, because it lacks nutrition and qi and blood, can not raise hair, and will not turn yellow. Old people are afraid of getting old. Originally, the crane's hair looks like a fairy, which is also pretty, and it has to be dyed black. However, the black hair and the criss-crossing grooves and beams on the face are not harmonious, and the old words are written on the face. If they refuse to accept it, they will not be able to change the carving of time.
Everything has two sides. Although dyeing your hair can satisfy your vanity and praise from your friends, it also has unhealthy risks. The ingredients of hair dye are very complicated, and most of them contain ingredients harmful to health. If it can make skin allergic, it is widespread, causing asthma and serious cancer. According to the survey, among more than 60 brands of/kloc-0, it is found that more than 50 brands of hair dyes contain carcinogens, and the safest way is not to dye hair. If people who dye their hair need to pay attention to something, there are several points:
First, choose natural, non-toxic or little toxic and side effects. When buying, you should carefully look at the main components of the product, and ask for bills from regular manufacturers.
Second, don't dye your hair too often. It's best not to dye it more than twice a year. Too much dyeing is risky.
Third, don't wash your hair for a day or two before dyeing your hair. Maybe this coloring is not very good, but it has a good protective effect on your skin and prevents hair dye from entering your skin.
4. Wash your hair thoroughly after dyeing and fixing, but don't shave your scalp with nails or combs when washing your hair, and don't hurt your scalp. Don't wash your hair for the next three days.
Fifth, don't use different brands of hair dyes to dye hair at the same time, so as to avoid chemical reactions.
Six, dye allergy test should be carried out before dyeing, and dye hair after 24 hours when there is no allergic reaction.
Today, the director tells you a sad story. A Korean brother went to the barber shop to dye his hair.
After dyeing my hair, I feel that my hair is not the same as before, but my head is getting bigger.
The left and right sides of the face are swollen and deformed, and the face is seriously asymmetrical (fatal)!
My brother's face is getting more and more swollen. When he went to see a dermatologist, the nurse elder sister was scared away by him and sent directly to the emergency room.
During the hospitalization, my whole face was swollen, and I couldn't see my original face at all. My eyes were so swollen that I couldn't open them.
Coincidentally, a 19-year-old British girl dyed her hair without completing an allergy test, and the same tragedy happened to her little brother in Korea.
High-energy warning ahead, please be prepared!
The whole head expands into a light bulb, which is larger than the general head circumference 10 cm. Even my tongue began to swell and my eyes were so swollen that I couldn't open them.
The girl below is also Korean. She bought a bottle of hair dye cream and began to dye it without gloves. Finally, the tragedy happened and she couldn't wash it off.
At the moment, 10 thousand xx are flying in the air.
Look at the latest black gloves. What is the texture? Is it realistic to have wood? I really want to know what is used to wash it off.
In fact, dyeing hair and perming hair have certain risks. Perm is to change the protein chain structure of hair with ammonium sulfonium, and curl the hair with the help of curling tools.
Perm is harmful to hair quality, and dyeing hair requires the use of oxidant to open scalp scales. Oxidants and other substandard toxic substances, improper dyeing will lead to hair scales falling off, dry, dull and inelastic. Inferior hair dye cream can also damage the skin, and Korean younger brothers and "light bulb" sisters will have hair dye accidents.
Because the chemical composition is used when dyeing hair, it will forcibly open the hair scales (which is very destructive), then bleach your own color and put it in the color you want. In principle, dyeing hair is more harmful than perming it.
The director said that proper hair color can improve dull skin color, reduce age and enhance fashion sense, and different hair colors can also bring different temperament.
There are too many benefits to dyeing your hair beautifully. From the fashion circle, hipster circle, entertainment circle and friends circle, almost everyone is dyeing their hair. However, while many people love beauty and dye their hair, they ignore the harmful substances in hair cream.
A while ago, in the quality inspection of 79 batches of cosmetics, a large number of hair dyes did not meet the standards. )
According to the action principle of hair dye, the director simply divides it into four types: oxidation type, metal type, plant type and direct type, and analyzes the advantages and disadvantages for you one by one.
Category I: oxidized hair dye.
Most of the hair dyes recommended by Tony in the barber shop and bought in the supermarket are oxidized hair dyes, and their chemical components include p-phenylenediamine, p-aminophenol and toluene diamine.
P-phenylenediamine is the most controversial one. It is the most effective ingredient in hair dye. Without it, it is difficult to fix the color on the hair. However, it is also a sensitizer. Even if used correctly, it may cause some people to be allergic. After allergy, skin redness, rash, yellow water, eye edema, etc. It may happen, and when it is serious, the whole body will swell and even be fatal.
On average, 1 person in 250,000 people is allergic to PPD, and the sensitization probability is about 0.0004%. This probability is very small, but don't take any chances and don't take an allergy test. Don't blame the director for not reminding you.
It is also reported that p-phenylenediamine is a toxic chemical, which can cause skin cancer, bladder cancer, leukemia (hematologic cancer) and so on.
P-phenylenediamine has a mutation. When it comes into contact with the scalp, it will enter the capillaries through the scalp and reach the bone marrow with blood circulation.
If it repeatedly acts on hematopoietic stem cells for a long time, it will lead to malignant transformation of hematopoietic stem cells, so the incidence of leukemia in people who dye their hair for a long time is higher than that in people who don't dye their hair. (That sounds reasonable ~)
But! But! But! So far, there is no medical evidence, and the European Union and the United States have not listed p-phenylenediamine as a carcinogen, nor have they banned the use of p-phenylenediamine in hair dyeing products.
In China, the content of p-phenylenediamine in hair dyes is limited. As long as it is not higher than 6%, you can use it with confidence and don't worry too much.
The second category: metal hair dyes.
It contains metals such as lead, iron and copper. The metal ions contained in the hair dye can easily penetrate into the hair to generate black lead sulfide and other substances, and the user's hair is gradually dyed black.
Grandma was trapped in a remote place. The face and neck are all black, and I thought it was a skin disease from a distance.
Unscrupulous businesses destroy many people, and many old people suffer greatly.
Moreover, heavy metals in hair dyes can cause damage to organs such as liver, kidney and brain, as well as hematopoietic system and nervous system. Both mercury and mercury compounds can cross the skin barrier, resulting in dark spots on the skin.
Arsenic and its compounds are toxic. If a large amount of arsenic is absorbed by the skin, it will cause dermatitis, pigmentation and other skin diseases, and skin cancer will easily form over time.
A 28-year-old female anchor saw a store selling well online. She bought a bottle of so-called pure natural plant hair dye online. When she used it for the first time, she had symptoms of nausea, vomiting and burning scalp. At this time, the seller said that it was used less. The girl obediently used the second box. Unexpectedly, she began to have difficulty breathing, shed tears and nosebleeds, and was finally taken to hospital for treatment.
Later, after testing, she was found to have seriously exceeded the standard of phenolic chemicals in hair dye, which caused damage to the nervous system, leading to dizziness, fatigue and numbness of limbs.
The third category: plant hair dyes.
Plant-based hair dye is made of substances extracted from the stems and leaves of plant flowers and dyed by physical and chemical methods. The main plants are henna, curcumin and crocus. Among them, henna is one of the widely used plant hair dyes.
Henna is often used in plant hair dyes, claiming that it won't hurt the scalp, and it can make hair brighter and more natural.
However, there is also great controversy about henna. Some experts pointed out that henna extract is toxic to bone marrow, which may lead to abortion after pregnant women use it.
In the article "Study on the Severe Toxicity of Henna Extract", it is believed that Henna will not only cause abortion in pregnant women, but also cause dizziness, loss of appetite, weakness, transient amnesia and other symptoms when the dose is large.
In 2007, the Ministry of Health issued the document "Ministry of Health's Reply on henna not as a component of hair dye", which clearly pointed out that henna should not be used as a component of hair dye.
However, in 20 13, the latest evaluation conclusion of the EU Scientific Committee on Consumer Safety (SCCS) was that when the mass fraction of fumoquinone was not more than 1.4%, it could be safely used as a hair dye.
Moreover, according to FDA regulations, it is safe to dye hair with pure henna ingredients, but some nail pollen with inferior ingredients is unsafe. However, the quality of nail powder sold in China is uneven. Without the national approval of the US Food and Drug Administration, it is best not to choose "pure plant hair dye".
Most of Tony's teachers use qualified hair dyes (oxidized hair dyes), while the pure natural plant hair dyes that claim not to hurt hair or scalp are very few. Branding the king of black hair who washes his scalp every ten minutes on a treasure is actually mostly just a gimmick.
The fourth category: direct hair dyeing.
Direct hair dyes include temporary and semi-permanent hair dyes, that is, hair pens, hair gels and hair sticks that were popular before. But it is only temporarily attached to the hair surface, and it will return to its original color when shampooing.
This hair dye has the least damage to scalp and hair, and it is especially convenient and quick. However, because its dyeing time is too short (one-time), it is only suitable for people with less white hair or who want gorgeous modeling.
Fairys who have developed the habit of dyeing their hair regularly, or babies who are troubled by white hair, can pay attention to the following points before dyeing their hair:
1, it is best not to wash your hair one or two days before dyeing, so that the oil secreted by your hair naturally forms a protective film to protect your hair follicles;
2. Be sure to do a skin allergy test. Apply the dye to the inside of the arm or behind the ear, and observe for 48 hours without redness, itching, tingling and other reactions before using it.
3. Don't dye your hair when your scalp and skin are damaged. The wound will sting when it comes into contact with hair dye, and there is a risk of inflammation.
4. It is good to dye your hair 2~3 times a year. After the number of times increases, it will destroy the scalp environment, cause serious damage to hair follicles and affect the growth of hair.
When choosing hair dyes, we must choose qualified products that meet the national standards: clearly marked, with production license, hygiene license and address, and the name and address registered by the dealer.
The director finally said a few words ~ Now most of the hair dyes produced by regular manufacturers are up to standard, so girls don't have to worry too much. As long as the hair dye meets the national standards, it is safe to use it in moderation as required.
That's what dyeing hair is all about. Whether dyeing hair or perming hair should be moderate, beauty is good, but not at the expense of health, otherwise everything is empty talk!
Thank you for your invitation. Personally, I don't think old people should dye their hair. First, although the old people dye their hair beautifully, the chemical composition of the hair dye is destructive to their hair. The antibacterial ability of the scalp of the elderly is reduced, the resistance is reduced, the scalp is accelerated, and the scalp cells are also very fragile. If you dye your hair frequently, it may cause scalp allergic reaction, leading to folliculitis, and serious hair loss. I can make a suggestion. There is no need to dye your hair. If you have foreign affairs activities, or if you have to, you can cut your hair short or shave your head. Wearing a wig will be convenient and beautiful. Now there are all kinds of wigs in the wig shop in the city, so you can choose your favorite wig belt.
Zhencaotang plant hair colorist professional advice, the elderly often dye hair, need to pay attention to the following aspects:
First of all, you must have an allergy test before dyeing your hair. Whether allergic or not, the method is simple. Mix the hair dye evenly and put it behind your ear. If there is no redness or itching within 48 hours, you can dye your hair normally.
Second, for the elderly with white hair exceeding 30%, black hair dye can directly cover white hair. If you choose a colored hair dye, please wear a proper amount of black to cover your white hair.
Third, try not to wash your hair within 3 days after dyeing your hair. You can wash your hair normally after the 72-hour fixation period. Do not use alkaline dandruff shampoo to wash your hair. The newly dyed color washes off easily.
Fourth, you don't need to wash your hair before dyeing it. Proper amount of hair oil can protect the scalp and prevent hair dye from invading the scalp.
Fifth, choose a healthy and safe dyeing paste. At present, dyeing size is mainly divided into chemical dyeing size and plant dyeing size. Choosing plants to dye their hair is mild, has no irritation to the scalp, and is more concerned about the head health of the elderly.
Hair blackening should be suitable for everyone, not everyone meets _ blackening. The heart is black and white, dyeing hair is the surface, the heart is white, it is snow on the frost, whiter, and natural white is really beautiful! Handsome figure, a black waterfall-like shoulder-length hair, appears to be a successful person who loves waist and has a clear mind. Tall and thin people are white but not dirty, and Baiyun Yun Lan shows his face! Others, it's better to dye them. Blackening turns to light roots, which originates from roots, causing anxiety and confusion, worrying about food loss, endocrine imbalance, unbalanced nutrition and less melanin in many restaurants. One night, there was a general in history who was afraid of being recognized when he went back to North Korea for border inspection. He was very worried! I woke up one night and found that my hair was white, which was different from that of primitive people, so I passed the test ... I had to go to a good shop to dye my hair, because the hair was evenly absorbed by the added chemical components, which had a certain adverse effect on the primary hair and stimulated the scalp to varying degrees, and could be absorbed by the skin into the blood circulation. Of course, it will be toxic, and the quality of the dye is guaranteed, and the absorption can be ignored. And then there's the allergic reaction? Hair salons are most worried about the mutual infection of fungi, because the items used are reused by many people, and even after disinfection and sterilization, they can not meet the medical sterilization standards. Don't run to health for beauty! '
