Today is the second day of the second month of the lunar calendar, but also the folk "dragon head", this day, the folk also have many customs, such as changing a hairstyle, good luck.
In order to get a good color, people often choose to get a haircut on this day, hoping that they can greet the spring with a new face.
Therefore, there is also an endless stream of people who dye and cut hair.
Whether it is simply covering up white hair or pursuing fashion, hair coloring has become a choice for many people to change their image. But there are also many doubts about hair coloring, and there are even rumors of carcinogenicity.
If you dye your hair regularly, you may even run the risk of causing cancer, is this true?
Is there really a risk of carcinogenesis in frequent hair coloring?
In fact, there is no medically proven association between the use of permanent stains and cancer.
However, some studies have found that stains may increase the risk of developing certain tumors, such as breast cancer, ovarian cancer, base epithelioma, etc., but their specific pathogenesis is still unexplained.
Therefore, at present, we only need to remember that ---- hair dye is risky, but we just need to pay attention to it and don't have to worry too much about it.
How can I dye my hair to avoid cancer?
First, choose a plant hair dye
When choosing a hair dye, some products that are not marked with special cosmetic approval numbers and health permits must not be purchased and used.
This type of hair dye is a chemical hair dye, which has a lot of carcinogens, and once used for a long time, the risk of carcinogenicity will be very high. Choose a plant-based hair dye, which has fewer carcinogens.
Second, sensitization before use
Be sure to do an allergy test before coloring your hair, and apply a small amount of hair dye behind your ears or to the inside of your forearm.
If you belong to the allergy or allergy-prone people, you need to wait 48 hours. If there is no redness, swelling and itching in the place where the hair dye is applied, or if there are blisters, rashes, etc., then the hair can be colored.
For other people, after applying hair dye, if these allergies do not occur within 24 hours, you can continue to dye your hair, and once any allergies occur, do not continue to dye your hair.
Third, pay attention to the time of hair coloring
When coloring hair, there are many people who leave the dye on their hair for a long time, thinking that this will be better at coloring, which is wrong.
When coloring hair, be sure to operate strictly according to the hair coloring time marked on the hair colorant. Once the time is too long, the hair dye will penetrate into the scalp, which has a certain impact on health.
Fourth, rinse well
After dyeing your hair, be sure to wash the hair dye thoroughly with water.
If the hair dye remains on the hair or scalp, it will not only have a greater impact on the hair texture, but also easily cause allergies, and even make people dizzy, scalp swelling and so on.
Fifth, the use of qualified hair coloring products
Unqualified hair dyes contain some carcinogens, such as phenylenediamine, which if it comes into contact with the scalp parts of the human body for a long time, it is very likely to cause some itching, swelling or skin damage to the scalp.
Do you still want to perm your hair after dyeing your hair, is it harmful to your hair?
In fact, this is not recommended.
Perm is essentially about lifting the hair scales of the hair, then using a potion to break the disulfide bond of the core keratin, applying a splint or curler, and finally closing its disulfide bond to change the hairstyle.
But if you burn your hair immediately after dyeing, the hair scales just close the door and open, it will hurt the hair, and the pigment particles that were previously embedded in it will be easily dispersed, resulting in discoloration.
Therefore, it is recommended to perm the hair one week apart after dyeing to give the hair a self-healing process. If it is bleached hair, the hair texture itself has been damaged, so it is best not to burn it.
