Hair dyeing is harmful to the body, not only hurting hair but also carcinogenic?Those who dare not dare to dye their hair should take a look

Near the Spring Festival, hair dyeing has become a "New Year’s ceremony" for many people. Dyeing a new hair color, hot new hairstyle, changing the face to face the New Year, the picture is beautiful and good.But there may be health risks behind the beautiful. It is best to understand before going to the barber shop and let yourself live a beautiful year and peace of mind!

The health risk of hair dyeing is the most concerned and most controversial is the "carcinogenic" problem.In fact, this is not empty.

Commonly used hair dye (permanent) hair dye, direct (semi -permanent or temporary) hair dye and natural hair dye.Among them, the oxidized hair dye has the most damage to hair quality, and most of them contain aromatic amine compounds such as pyramide, amino amino pedazone, and 2-pyrine, and these compounds have confirmed harmful to the human body.

However, the carcinogenicity still lacks the in vitro test of human or animals that most studies are observation research and have certain limitations.Women use permanent hair dye, breast cancer risk may be higher

In the magazine of "International Journal of Cancer", a paper has published a paper. After collecting and analyzing the data of 46,709 women, researchers found that women who use permanent hair dyes regularly have the risk of breast cancer than unused hair dyeing hair dyeing hair dyeWomen of the agent are 9 % high.

Among African-American women, the risk of breast cancer will increase by 60 % every 5-8 weeks or longer; while white women will increase the risk of 8 %.However, the study did not find the correlation between the use of semi -permanent dyes or temporary dyes and the risk of breast cancer.

A foresight study has also published a forward -looking research on the famous global medical journal "British Medical Journal" (BMJ), which has been followed up for nearly 120,000 women.It is not related to cancer -related mortality, but the risk of basal cell carcinoma, breast cancer (estrogen receptor negatives, progesterone receptor negatives, hormone receptor negatives) and ovarian cancer have increased.Men use permanent hair dye, and the risk of prostate cancer has soared

Men’s hair dyeing may also have carcinogenic risk.

The research team of the National Cancer Institute of Cancer has analyzed the data of 28,795 Finnish men for 28 years. After adjustment of multiple variables (such as age, family history of prostate cancer, diabetes, etc.), it is found that men do not use oxidative hair dyeing agentsCompared with, the risk of prostate cancer in men with oxide hair dye increased by 77%.

In a comparison study of a retrospective case of 608 men in Taiwan in Taiwan, it was found that the use of hair dyeing agents was significantly related to the risk of male prostate cancer by 115%; the other was incorporated into the queue research results of 703 Geneva men.Men’s prostate cancer is related to the use of hair dye.

Although the use of hair dye must be carcinogenic at present, the risks of them need to be paid attention to.

The World Health Organization International Cancer Research Agency has listed "hairdresser or hairdresser (occupational exposure)" as a list of 2A carcinogens, that is, it is likely to cause cancer on people. Such carcinogens have limited evidence of carcinogenicity on people, and carcinogenicity of experimental animals is carcinogenic.Full evidence."Hair -dyeing products (personal use)" are type 3 carcinogens, which is suspicious of human carcinogenicity, and there is no sufficient human or animal data.

Frequent, long -term, and large hair dyeing, the harm of hair, or even the body cannot be ignored.

1. Broken hair quality

The irritating ingredients in the hair dye have strong oxidation, which can easily damage the hair and scalp hair follicles, resulting in dry hair and dryness.

2, hair loss

The chemicals in the hair dye may cause inflammation of the scalp and hair follicles. It can easily shrink the hair follicles for a long time, the hair changes from thickness, and increases the risk of hair loss.

3. Allergies

When dyeing hair, hair dye directly comes into contact with the scalp, and after heating, it may make the benzene organic substances enter the capillaries through the scalp, which can easily cause skin allergic symptoms. In severe cases, even allergic shocks will occur, which is life -threatening.

4. Contact dermatitis

In the outpatient clinic, cases of contact dermatitis due to hair dyeing are very common. After dyeing the allergies, edema erythema, pimples, blisters, even erosion, exudate, itching and other symptoms will occur.The above symptoms will fade, and those with severe condition also need to be treated with glycopytic hormone.

In summary, in order to avoid "falling from the head", for those who need hair dyeing, you should try to take safety measures to protect yourself:

① Select hair dye produced by regular manufacturers.Gong Wuzhou, deputy chief physician of the dermatology department of the Second Traditional Chinese Medicine Hospital of Guangdong Province, pointed out that at present, regular hair dye products have long been disabled in phenylramine, and consumers need to be vigilant when buying.

② Do a good skin test before dyeing.The general test site is recommended to be the skin behind the ear. Take a small amount of mixed hair dyeing products for testing to observe whether there is an allergic reaction.

③ Reduce the number of hair dyeing.It is recommended to not exceed 2 times a year; middle -aged and elderly people who are dyed and black all year round can only dye new white hair.

In addition, children under 16 years of age, women who are pregnant and breastfeeding, patients with asthma, urticaria, and allergic diseases have rashes on their faces, or people with scars, damage, sores, dermatitis, etc. are not suitable for dyeing hair.”””
