what does hair dye do to hair

Painting is old. From time immemorial, humans have had a great deal of interest in coloring their hair and painted their hair using herbs like Henna. Of course, this interest has continued until today. Until a few years ago, the use of hair dyes, in particular, more chemical colors for women, was also commonplace to cover white hair, but unfortunately today, the use of chemical paints among young people and adolescents is also common, but it can also cause a lot of damage. To follow.

It is necessary to know that any cosmetic product, and in particular its chemical type, is not uncomplicated and, despite the fact that, as often as once, news about the effects of the use of chemical hair dye is published by researchers, but also consumption statistics This chemical is increasing.

Now that you can not stop people from paints and color hair and can not be discarded, then at least use them properly and properly, and even use plant colors instead of chemical paints.

Natural hair color

Each hair is composed of two main parts of the pod and root. The pod is the one that covers around the stem and root. Hair shaving has two types of pigments: brown to black pigments and golden to red pigments. Depending on the breed, the type of pigment and the resulting color of the hair are different, and if the pigments disappear, the hair becomes white.

Familiarity with the color of chemical hair

The color of the hair is divided into two categories: temporary hair color and permanent hair color.

A) The color of the temporary hair

Under the color of the temporary hair color, there is also another category called half-time. Temporary hair colors are colors that last only once as shampooing. These colors do not penetrate into the hair and only stick to the hair. Half-time paints that are most commonly used for white hair are 4 to 6 times longer lasting shampoos. Due to the presence of poor oxidizing materials and lack of ammonia, these hairs are less harmful to the hair, and even sometimes used as a natural hair dye enhancer.

B) Permanent or fixed hair color

The durability and durability of these colors are longer and longer on the hair. These colors are the most commonly used dyes in beauty salons, and most people prefer to use these colors, but they are unaware of their potentially harmful effects on the hair and scalp.

Permanent hair color contains ammonia and oxidants. Oxidants act as a catalyst and cause the color to remain permanent on the hair, but it's better to use weaker oxidants because of the damage that strong oxidants have on the hair. Strong oxidants cleanse more sulfur from the hair, resulting in stiffening hair and decreasing diameters.

Ammonia separates the hair cuticle by allowing hair to penetrate into the hair, but in some hair colors, the amount of ammonia is so high that it separates excess sulfur from the hair, resulting in a thin, fragile hair Gets

White hair, a phenomenal phenomenon

These days white hair is very common at young ages. Hair bleeding depends on a number of factors, one of the most important being heritable. Of course, diseases like vitiligo can also be a bleeding agent. In addition to hair, it also whitens the skin and some parts of the body. Other important factors that can be mentioned are false nutrition. Lack of vitamins such as B vitamins and zinc and selenium deficiencies are effective in hair whitening.

If hair whitening is inherited, the therapeutic effect does not have the effect of preventing whitening, but if hair whitening is false due to illness or nutrition, it can be prevented by treating the medicine with further whitening.

However, one of the main reasons and motive for most people to hide these white hair is to paint their hair. You should also contact people who say they do not know why my white hair loses color after several times, or some people say that the color of my white hair does not color. In fact, white hair, especially in some parts of the head, is resistant to color, especially in the area around the hair, or they quickly lose their color.

Anything that causes the natural structure of the hair to get out of the ordinary is considered harmful to the hair. For this reason, as much as possible, the use of special chemicals should be used for grinding, dyeing and so on.

Hair coloring during pregnancy is prohibited

Since research has not yet been completed, it can not be claimed that 100% of hair has a harmful effect on the fetus, but as you know, the skin of the palm of the head can absorb some of the chemicals in the color and enter the bloodstream and Since the first trimester of pregnancy is embryonic development and the embryo is very sensitive and vulnerable at this time, it is recommended that pregnant women should not use chemical dyes until the end of pregnancy, especially in the first trimester of pregnancy.

These colors can cause abortion, so it's not advisable to use it during pregnancy.

Complications of hair color

Some researchers believe that excessive use of chemical hair dye causes bladder cancer and non-Hodgkin's lymphoma (a type of leukemia).

Also, frequent or incorrect use of hair color, especially the color of permanent hair, can damage hair and cause hair loss. Dry and shriveled hair is also one of the damages caused by hair loss.

Frequent use of hair dye causes skin sensation, dandruff, itching and even redness of the scalp. If the chemicals in the paint are strong and the person is allergic to these materials, there may be burns in the head, the effects of which can even last until the rest of the life. This sensitivity is due to the presence of a substance called parapheniline diamine (PPD) in hair dye. Usually symptoms of this sensation include redness of the scalp, itching, burning and blistering, and scaling of the scalp. Due to the sensitivity of this substance in some people, in some countries the use of this substance in hair dye is prohibited, and in many colors it has been significantly reduced, but, however, people who are allergic to this substance , Do not use this hair color.
