Excuse me, is perming and dyeing hair very harmful to the human body

In response to the widespread public concern about the safety of hair dye products, the person in charge of the relevant department of the Ministry of Health said yesterday that hair dye products may have allergenic effects, but the causal relationship between hair dyeing and carcinogenesis cannot be confirmed. The raw materials of hair dye products in China are restricted substances in cosmetics, and relevant experts remind the public to pay attention to the fact that they should read the labels and instructions in detail before using hair dye products.

There is insufficient evidence that hair color products cause cancer.

Regarding the carcinogenic effect of hair dye products, the person in charge said that although there are research reports that hair dye has been found to be related to certain cancers, the International Agency for Research on Cancer (IARC) has evaluated the relationship between hair dye and cancer and believes that there is insufficient evidence to prove that hair dye causes cancer.

It has recently been reported that the cause of cancer in hair color products is the chemical p-phenylenediamine. In this regard, the Ministry of Health said that p-phenylenediamine is one of the widely used raw materials for hair dye products, and it is also a known sensitizer, and correct use may also cause allergies in some people; However, at present, there is insufficient evidence in animal experimental data and epidemiological data to prove that p-phenylenediamine is a carcinogen, the European Union has not included p-phenylenediamine in the list of carcinogens, and the United States, the European Union and other countries have not banned the use of p-phenylenediamine in hair dye products.

A variety of hair dye products are allergenic.

Although hair dye is not confirmed to cause cancer, the person in charge reminded the public that the raw materials of various hair dye products have a certain allergenic effect. Depending on the sensitivity of the consumer's body, the severity of the sensitization reaction varies.

It is precisely in consideration of the particularity of hair dye products that China manages hair dye products as special-purpose cosmetics and implements the marketing authorization system, that is, hair dye products must undergo a series of toxicology, hygienic chemistry and other tests, and pass the risk assessment of the expert committee before they can be marketed.

Hair dye labels must be labelled with a warning message.

In order to further strengthen management, since January 1 this year, China has officially implemented the "List of Hair Dye Raw Materials (Trial)", which stipulates the current permitted use of hair dye raw materials and their restricted use conditions based on the safety evaluation of raw materials; At the same time, it is mandatory to mark the warning on the label of hair dye products: "For some individuals who may cause allergic reactions, they should be tested in advance according to the instructions." Do not use eyebrow tint and eyelashes, rinse immediately if it gets in your eyes.

Appropriate gloves should be worn for professional use". For products that use allergenic raw materials, the Ministry of Health requires hair dye factories to label the corresponding raw material information, for example, the label of hair dyes containing p-phenylenediamine must be marked with the words "containing phenylenediamine" in addition to the warning language.

Authoritative reminder: The Ministry of Health recommends that consumers should read the product label and instructions in detail when dyeing their hair, and conduct an allergy test in advance; People with allergies and those who have had an allergic reaction to hair dye should be cautious about dyeing their hair; Minimize the frequency of hair coloring.

Hair dye damage should be greater.

Hair dye contains carcinogens.

Perming hair does harm the body, as follows:

1. Harm to human internal organs: Hair dyes, especially chemical hair dyes, contain a lot of toxic and even carcinogenic chemicals, such as aniline, if they are exposed to ** during the hair dyeing process, they may cause some damage to the internal organs of the human body after being absorbed. If the hair is dyed repeatedly and frequently, carcinogens may enter the body and cause malignant transformation of body cells.

After a period of time, some people will develop bladder cancer, kidney cancer, and even blood malignancies, such as leukemia;

2. Affect fetal development: In the process of dyeing hair, if the hair dyeing substance is absorbed into the body, and women may affect the fetus during pregnancy or pregnancy, so it is best not to dye hair during pregnancy and breastfeeding;

3. Cause allergies: hair dye can also cause harm to the local, such as staining the scalp, some people can have hair dye allergies, causing hair dye allergic dermatitis, which can lead to local redness, swelling, erosion, itching and other symptoms;

4. Affect the hair quality: Hair dye also has a certain amount of damage to the hair itself, which contains oxidants and other substances that can damage the hair shaft, and long-term hair dyeing will make the hair dry and dull.

The hazards of perming and dyeing hair may include allergic reactions, toxic reactions, hair loss, ** damage, etc.

Many chemically synthesized hair dyes generally contain benzene organic compounds, especially p-phenylenediamine. P-phenylenediamine is a colorant that must be used in hair dyes, which has different degrees of harm to the human system and organs, and is an internationally recognized carcinogenic substance.

Hair dyeing can affect hair quality, and over-coloring can make hair dry, split ends, brittle, and easy to break.

In addition, hair dyeing may also have a negative impact on the body's liver and kidney function, the liver is the body's most important detoxification and detoxification organs, and toxic substances such as silver nitrate, lead, and benzene in hair dye will directly cause toxicity to the kidneys and liver.

In the process of dyeing hair, the hair dye will come into direct contact with the scalp, and there is a certain chance of causing contact allergic reactions to the scalp. If you have eczema, scalp moss, or a broken scalp, it is recommended not to dye your hair, otherwise it will cause infection to the wound.

Occasionally, a perm will not cause great damage to the body, often perm and dye the hair, which contains toluene diamine, which can cause cancer if used regularly, so do not perm more than twice a year.

Perming hair is less harmful to the body, perming hair may damage the hair and cause dry hair, it is not recommended to dye hair at ordinary times, and it is not recommended to perm hair.

How much damage does perming hair do to the body? Hair dyes, especially chemical ones, contain many toxic and even carcinogenic chemicals. For example, aniline.

In the process of dyeing hair, if it is exposed to ** after being absorbed, it may cause some damage to the internal organs of the human body, once a time, the damage may be small, if the hair is dyed repeatedly and frequently, carcinogens enter the body, and after more, it may induce malignant transformation of body cells. It is possible that after a period of time, someone will develop bladder cancer, kidney cancer, and even blood malignancy. For example, leukemia, so when we choose to dye and perm our hair, we must choose some qualified and regular plant-based hair dyes.

Try to avoid less hair dyeing and less contact with the scalp.

Hair dye contains ingredients that are harmful to the human body, which can easily lead to scalp allergies, redness, swelling, and itching in mild cases. Severe cases may develop herpes, rashes, and even affect the whole body. Perm potions are generally alkaline ingredients, and the oxidation of the potion can cause the scals of the hair layer to be destroyed, which is harmful to the hair and hair follicles, and damage, resulting in keratin degeneration, causing hair to dry out and fall out.

Because perms contain heavy metals such as lead and mercury. If you perm your hair for a long time or perm frequently, it may lead to cancer and other diseases.

Perming the hair can cause allergic hair loss on the scalp, and the scales of the hair layer will be destroyed during the perming process. The internal structure of the hair is in an unprotected state, which will cause the loss of internal moisture and nutrients, which is harmful to the hair, scalp and hair follicles, and will more or less denature the keratin protein of the hair, making the hair easy to yellow, brittle, easy to fall out, no luster, no elasticity.

The dangers of dyeing and perming hair.

Dyeing and perming hair is something that modern women often do. In order to make their hair more beautiful and their image more high, many women choose to perm and dye their hair. Perming hair actually has a lot of harm to both the body and the hair, so what are the dangers of dyeing and perming hair?

1. Hair dyeing may cause cancer.

The claim that hair dyeing causes cancer mainly comes from a chemical component contained in hair dye: p-phenylenediamine (PPD). So is p-phenylenediamine carcinogenic?

From a chemical point of view, p-phenylenediamine is definitely toxic, and it is highly toxic when taken orally, which is the same as aniline. It has a strong sensitizing effect on phenylenediamine and can cause contact dermatitis, eczema, and bronchial asthma.

Many people have allergies and burns after dyeing their hair, all because of p-phenylenediamine. Some scientists have pointed out that long-term exposure to p-phenylenediamine can cause ** cancer and lymphoma, but the American Anti-Cancer Society (ACS) pointed out that there is no direct evidence that p-phenylenediamine in hair dye is enough to cause cancer. What are the disadvantages of frequent perm and hair dyeing, mainly because the chemical ingredients in hair dyeing are harmful to the human body, and there is also a risk of cancer.

If you over-dye your hair and do whatever you want, it is likely to lead to unbearable disasters.

2. Perming can damage hair.

Contrary to what many hair lovers think, coloring your hair is not as simple as applying color to your hair. Hair coloring uses the alkaline ingredients in the dye cream to open the hair cuticle of the hair layer (the scales on the hair open when exposed to alkali), and the artificial pigment enters the cortical layer of the hair and combines with a part of the natural pigment to form the desired color.

Therefore, hair dyeing is a process that deeply changes the structure of the hair, forcibly opens the hair cuticle and forms a new structure, which violates the biological physiological characteristics and natural laws, and brings permanent irreversible damage to the hair. After the cuticle is opened, the internal structure of the hair is in an unprotected state, which will cause the internal moisture and nutrients to be lost, which is harmful to the hair, scalp and hair follicles, and will more or less denature the keratin of the hair, making the hair easy to yellow, brittle, shiny, and elastic. What are the disadvantages of frequent perm and dye hair?

Many people feel that their hair is not as good as before after dyeing or perming their hair, which is not an illusion, especially for people who often perm and dye their hair, their hair has been scarred and difficult to repair.

3. Cause a lot of hair loss.

Due to the above reasons, it is also obvious that hair loss is caused by perming hair. On the one hand, perming and dyeing hair will lead to poor hair quality, and hair is easy to fall out; On the other hand, due to the damage to the human body caused by perming hair, it can even affect hair follicles! For example, hair perms can be more or less absorbed by the scalp and difficult to excrete, which will always affect the activity of the hair, while hair dyes can cause many allergic reactions, and hair follicles are also the most direct victims.

This article introduces some of the hazards that will occur in dyeing and perming hair, if you need to perm your hair, then you must act carefully, otherwise it may cause greater damage to the body and hair, and do not cause lifelong regrets for the sake of temporary beauty.

1. Cause disease.

Because hair dye contains some chemical ingredients, which will affect hematopoietic stem cells and is a carcinogenic substance, I hope you can pay more attention.

2. Cause hypersensitivity.

Hair dyeing can also cause hypersensitivity, which is a very common occurrence, usually in the early stages of hair dyeing, this hypersensitivity reaction is not obvious, but after a few times it will become more severe.

3. Poisoning.

If you use hair dye for a long time, as long as 1% is absorbed into the human body, it will accumulate poison, in which chemicals combine with certain cells, and the DNA in the nucleus is damaged, causing cell mutations, and inducing cancer, bladder cancer, leukemia, etc., for which we warn and warn against the disease from the onset.

4. Lead poisoning symptoms.

Hair dyes also contain acetic acid: lead, which contains 5 10 times more lead than household paints and pigments. After lead enters the human body, it is difficult to excrete it from the body, causing the accumulation of poisoning, dizziness, headache, fatigue, numbness of limbs, leg cramps, abdominal pain, and a series of lead poisoning symptoms, and enters the liver, kidney, and cerebral marrow, destroying the functions of these organs, and in severe cases, losing labor.

5. Hair damage.

The hair coloring process can affect the moisture imbalance in the hair, leading to the denaturation and reduction of a large amount of protein, etc. As a result, the hair becomes brittle, the fibers break, and the hair loses its natural softness, strength and shine.

6. Hair loss.

The rapid and slow stimulation of hair dye can cause inflammation of the scalp and hair follicles, and over time, it will cause hair follicles to shrink, resulting in hair from thick to thin, and finally hair loss. In life, for hair dyeing, we must be cautious, if you really want to dye your hair, it is best to use some good hair dyeing products, I hope you can pay attention.

Hair dyeing is harmful to the body, which can easily affect physical health, affect fetal development, affect hair quality, and cause allergies.

Hair dyes contain certain chemicals and carcinogens, and dyeing hair once or twice may not have much effect on the body. For people who frequently dye and perm their hair, it is easy to induce malignant changes in body cells, and then lead to the appearance of cancer, such as leukemia.

If it is during the period of preparing for pregnancy, pregnant women and lactating periods, it will have an impact on the fetus and the baby, and it is easy to affect the development of the fetus, resulting in fetal malformations and other problems.

The ingredients in hair dye have an impact on the health of the hair, and long-term frequent hair dyeing can easily lead to dull hair and special dryness.

The ingredients in hair dye may cause allergies to the scalp, so it is best not to try hair dye lightly for people with allergies.
