CCTV once did a statistic on hair coloring, and of the 2,600 people who received the statistics, more than 90% of them had dyed their hair, and nearly 40% of them often dyed their hair.
With the development of the times, hair dyeing and perming has become more and more common, and even many elderly people will often dye their hair in order to turn white hair into black hair.
Although hair coloring is good-looking, the negative news related to the Internet is also endless, causing cancer, allergies, hair loss...
Which claim is true? Is hair coloring really bad for the body? Are there any remedies? Make it clear all at once today!
01
She was diagnosed with lymphoma 30 times a year
Before I start today's article, I would like to talk about a news I saw before.
Her name is Xiaolin, she is 28 years old and has been in love with her boyfriend (ex-boyfriend to be exact) for 4 years.
Finally, last year, the two began to talk about marriage, but before she could come and envision a better life after marriage, she was slapped by reality.
It turned out that Xiaolin suffered from congenital albinism, and the most typical symptom was that the skin and hair were white. It is also for this reason that the marriage between the two has been strongly opposed by the man's parents, who believe that it is likely to be passed on to future children.
Therefore, Xiao Lin began to dye her hair frantically, trying to save the feelings of these 4 years.
As long as the previous color faded, or new hair grew, she would not hesitate to go to the barbershop and dye it black. In just one year, she has dyed her hair no less than 30 times.
The naïve Xiaolin thought that as long as she did not have gray hair, she could marry her boyfriend. But the reality is that she is waiting for the news that her boyfriend is married to someone else and that she has been diagnosed with lymphoma...
Such a tragedy is really sad, and in reality, there are very few people like Xiaolin who dye their hair with high frequency, but it should be noted that many people dye their hair all year round, will this also be harmful? Is there a risk of carcinogenicity?
02
Does hair coloring really cause cancer and hair loss?
Whether hair coloring is carcinogenic or not, hair dyes play a vital role. At present, common hair dyes on the market are mineral hair dyes, plant hair dyes and chemical synthetic hair dyes.
Due to the poor stability of plant dyes and the easy fading, they are rarely used in the hair industry, and most of them are chemical synthetic hair dyes.
Out of concern about carcinogenicity, Consumer Report has conducted an in-depth review of 11 common hair dyes on the market. The end result was that none of these hair dyes detected p-aminophenol or o-aminophenol, but seven hair dyes had excessive concentrations of p-phenylenediamine and resorcinol.
It should be noted that if a large amount of exposure to p-phenylenediamine in a short period of time may cause acute poisoning. Therefore, the mainland has a clear definition of the content of p-phenylenediamine in hair dyes, which is 2-6%.
As a class of three carcinogens, although there is no clear evidence that p-phenylenediamine can directly cause cancer, long-term exposure still has a carcinogenic risk. In other words, frequent hair coloring and the use of hair dyes with excessive phenylenediamine content do have a certain risk of carcinogenicity.
However, occasional hair coloring does not have to worry too much, after all, putting aside the dose to talk about toxicity is to play hooligans, as long as you pay attention to the frequency.
It is also important to note that p-phenylenediamine is a strongly sensitizing substance. Hair dye can easily touch the scalp when coloring hair, and if it is a person with sensitive skin, it is very likely that allergic reactions will occur, resulting in symptoms such as rashes, yellow water and eyelid puffiness.
The question of whether hair coloring will cause hair loss at all, the answer is yes!
Those who have been dying and perming their hair for a long time, their hair has become more or less thinner, and they should be vigilant against hair loss at this time. Because of the strong irritation of hair dyes, frequent hair dyeing will cause an inflammatory response to the scalp and hair follicles, and the hair follicles will shrink and the hair will become thinner, and hair loss is naturally inevitable.
03
What are the dangers of hair coloring?
Frequent hair coloring, in addition to the risk of carcinogenicity and hair loss, also has damage to all parts of the body.
allergic
This we have already said before, allergic reactions can be large or small, although it does not sound serious, but do not take it lightly.
CCTV has reported related cases, a 47-year-old female teacher because of her own history of hair color allergies, after 10 days of hair coloring without listening to dissuasion, the allergic reaction worsened, and the rescue was ineffective and died!
Liver damage
In order to enhance the dyeing effect, many hair dyeing products on the market will add lead, mercury and other metal substances. Once used for a long time, it is absorbed by the scalp and enters the body, which may cause chronic damage to organs such as the liver and kidneys.
Diseases of the blood system
When dyeing hair, the benzene organic matter in the hair dye will enter our body through the scalp, and damage the hematopoietic stem cells, and long-term frequent hair dyeing blood system diseases will naturally occur.
Damaged hair
When hair is frequently exposed to high temperatures, the moisture in the hair will be unbalanced, and frequent hair coloring may make the hair lose its toughness and luster, and even make the hair dry and the fibers broken.
04
These types of people are not suitable for perming and dyeing hair!
People with sensitive skin
This has been said before, so people with sensitive skin are best to do an allergy test behind their ears before dyeing their hair.
People with broken scalp
People with diseases such as eczema, folliculitis and psoriasis, because the skin barrier is incomplete, it is not recommended to perm and dye their hair, otherwise it will only aggravate the condition.
People with liver and kidney problems
There are liver and kidney problems itself, and its own "detoxification" ability is no longer enough, and it is best not to increase the burden of liver and kidneys.
Elderly and children
Children's skin is delicate and more likely to have allergic reactions; while the elderly are not suitable for perming and dyeing their hair because of their weakened liver and kidney function.
Pregnant and lactating women
First, women during pregnancy are more sensitive and more likely to have allergic reactions; second, if they are hair-colored chemicals during lactation, they can enter the body and enter the baby through breast milk.
Menstruating women
During menstruation, women tend to have weaker resistance and more sensitive skin, and hair coloring may affect endocrine, resulting in a series of health problems.
