Whether it is simply wanting to become beautiful or wanting to cover up white hair, hair coloring has become a choice for many people to change their image.
But there are more hair coloring, more questions to question, and some people also choose to refuse to dye their hair.
But then again, is hair coloring really that unsafe?
Hair coloring does have some unsafe factors
First, allergies
Hair dye does contain some substances that may have an impact on health, so for some friends with allergic constitutions, it will be easy to have some allergic reactions, light may appear scalp redness, itching, desquamation and other mild symptoms, heavy may appear scalp, face edema, long blisters and other serious allergic reactions.
Once the body has allergy symptoms, it is necessary to go to the hospital for examination and treatment in time to avoid delaying treatment, after all, people with sudden allergic inflammation will also die.
Many hair dye instructions will mention that it is recommended to do a skin allergy test between hair coloring agents, so that you can clearly know whether you have symptoms of allergies to hair dyes.
However, when testing, the hair dye can only be used on the hair and it is not recommended to directly contact the skin, because the hair dye itself has a certain irritating effect on the skin.
If it comes into contact with the surface of the skin, it will easily cause the skin to have a bad condition and destroy the skin mucous membrane.
Second, the hair is damaged
Frequent use of hair dye will continue to damage the hair, resulting in the hair becoming thin and fragile, and it will be vulnerable to damage in the later stages, the hair will gradually become more fragile, and even pathological hair loss will occur.
Third, heavy metal poisoning
The Cosmetic Hygiene Code (2007 edition) stipulates that hair dyes are allowed to contain certain doses of heavy metals, such as mercury, lead, arsenic, but within reasonable limits.
Some hair dyes that are not very good quality will have heavy metals exceeding the standard, so repeated hair coloring may cause chronic lead poisoning.
Is there a risk of carcinogenesis in hair coloring?
From the current research experiments, no association has been found between the use of permanent hair dyes and most cancers, but hair dyes increase the risk of developing certain tumors, such as base epithelioma, breast cancer or ovarian cancer.
But the cancer itself does not appear for very few reasons, often under the premise of various conditions together, so occasionally once or twice hair coloring, and the use of qualified products on the market, do not have to worry too much.
If you are engaged in the hairdressing industry, long-term contact with the skin or inhalation of hair dye through the respiratory tract, there may be some hidden dangers, so you also need to do relevant protective measures when working, such as wearing masks or gloves.
How to reduce the impact of hair coloring on the body?
First, before coloring your hair, fully test the risk aversion
Before choosing to buy a hair dye, you need to understand the composition of the hair dye, and you need to wear gloves when blending hair coloring, and try to use the previous products.
In addition, 1-2 days before each hair color, a skin test can be performed first, and some hair dye can be applied to the skin to observe whether there is any allergy.
Second, pay attention to the measures of shampooing before and after hair coloring
After 4 to 6 hours after the hair color, the hair is washed, at which time the hair dye is completely dry, which not only prevents allergic reactions, but also reduces the risk of carcinogenesis.
You should pay attention to scalp cleaning within a few days after hair coloring, never let excess hair dye remain on the scalp, and avoid scratching with your fingers.
Third, avoid re-dyeing your hair for three months
Frequent use of hair dye is easy to cause damage to the hair scales, making the hair easy to break, such as repeated hair coloring within three months, it will cause secondary damage to the hair that has not fully recovered.
Fourth, special groups of people should not dye their hair
For special people such as lactation, pregnancy and hypertension, asthma patients, hair dyeing must be cautious, or do not dye hair, otherwise the harmful ingredients present in the hair dye are easy to cause harm to the human body.
Fifth, choose a light color hair dye
Although most hair dyes contain some chemical components, relevant experiments have found that lighter color hair dyes are less harmful to the human body.
During the hair coloring process, if the hair dye accidentally flows into the eyes, it is necessary to rinse it with water immediately and repeatedly.
If you find some allergies after dyeing your hair, you need to rinse the hair dye stored on the scalp with water as soon as possible, and if you are serious, you need to cut off the hair that has been dyed to avoid exacerbating allergies.
After all, dyeing your hair is just for fun, and if you are careless and let your body suffer, it is really not cost-effective!
