Xiao Dong is not only enterprising, but also has an online personal image and temperament. Coupled with the high monthly income, Xiao Dong has enough strength to maintain his figure. To say that Xiaodong's biggest hobby should be dyeing his hair. Almost every month or two, Xiaodong will make a new hairstyle, which makes people shine at the moment every time.
Perhaps because of frequent dyeing, Xiaodong's hair has become more and more rough, and some time ago, he even had dizziness and headache. I thought I was overworked, so I didn't take it seriously, but after a few days' rest, the situation became more serious.
In desperation, Xiao Dong later went to the hospital for examination. After careful examination, the doctor found that Xiaodong's headache was actually caused by long-term hair dyeing. Due to frequent hair dyeing, Xiaodong's scalp is seriously allergic and there are many lumps of different sizes.
The doctor said: this situation belongs to skin cancer, which is a very serious skin disease. Many people are diagnosed with skin cancer because they often dye their hair. This is because hair dye contains a lot of chemical components, which will damage scalp and subcutaneous connective tissue for a long time, thus inducing malignant tumors.

Frequent "dyeing hair" can cause cancer. Is it true or not? The research results have been published, and I will understand after reading them.
On September 2, 2020, the British Medical Journal, one of the four top medical journals in the world, published a study on the relationship between the use of hair dyes and cancer risk and mortality. The results show that the use of hair dyes is closely related to the increased risk of basal cell carcinoma, breast cancer, ovarian cancer and lymphoma.
This is an ongoing large-scale prospective cohort study. From 1976, * * American female nurses aged 30-55 12 1 700, the research was collected. From 1976, 1 subjects participated in the study until 2000.
The results are as follows:
1, the use of hair dyes will increase the risk of basal cell carcinoma of the skin, especially for women born with light hair, the risk of basal cell carcinoma of the skin will increase by 6%.
2. Using hair dye will increase the risk of breast cancer and ovarian cancer. The frequency and dosage of hair dyeing are positively correlated with the incidence of breast cancer. Every 50 times, the risk of breast cancer will increase 1% ~ 2%. The risk of ovarian cancer in subjects who use hair dye is 2 1% higher than that in subjects who do not use hair dye.
3. Women with natural dark hair who have used hair dye have an increased risk of lymphoma by 28.9%, but this situation has not been observed in female subjects with light hair. Of course, this conclusion remains to be discussed and needs further confirmation.
4. The use of hair dye will not increase the risk of other solid malignant tumors, bloody malignant tumors and other cancers, such as brain tumor, colon cancer, rectal cancer, kidney cancer and lung cancer.
In fact, this study is not the only one that proves that frequent hair dyeing increases the risk of cancer. In the International Journal of Cancer on February 3, 20 19, it was also published that people who use hair dyes or hair straighteners are more likely to get breast cancer than those who never use such products.

What can be done to reduce the damage caused by dyeing hair?
1, pay attention to the frequency of hair dyeing.
Generally speaking, experts advise you not to dye your hair. If you must, you must pay attention to the frequency of dyeing your hair. Hair dyeing interval should be at least 3 months, and it is best to go to a professional barber shop for hair dyeing. Middle-aged and elderly people should not dye their hair more than twice a year. Do not bake oil one week before dyeing, and do not wash your hair on the day of dyeing. The oil secreted by the scalp has a protective effect.
2. Try it before dyeing your hair
In daily life, many people are allergic to hair dyes. Before dyeing, they can try to be sensitive to the delicate skin behind the ears or inside the skin. If there are no allergic reactions such as erythema, papules and blisters, it can be dyed again. When you dye your hair, you can apply some lotion or vaseline ointment around the hairline, which is better for cleaning to prevent it from being contaminated by medicinal liquid. Before dyeing hair, you can also remind the barber to apply the hair dye as far as possible to the hair root 1 cm to avoid direct contact with the scalp.
Don't trust pure natural products.
Nowadays, many hair dyeing brands are all under the guise of pure natural products. In fact, it is difficult to dye hair black with pure natural hair dyes. Experts suggest that you choose a light-colored or easily faded hair dye, in which the content of p-phenylenediamine is relatively small, and it is less harmful to human body.
4. Choose the right detergent products
When choosing a shampoo, try to choose a shampoo as selectively as possible, otherwise the alkaline shampoo will easily make the hair fade. In hair dyeing products, the brighter the color, the easier it is to decompose. Alkaline shampoo will make the unstable red color fade more seriously. Hair conditioner is acidic, and it is easy to fade when used too much, so you should also buy a hair conditioner specially designed for dyeing hair.
