Natural black hair color

Nowadays, many girls use various chemical ingredients to dye their hair to make their hair look better. They dye their hair into starry sky color, khaki color, and other different colors. After using it for a long time, they will feel bored. So if everyone wants to dye their hair back to natural black, there are still many ways to dye their hair naturally black, which need to be understood clearly.

Classification

Hair dyes are divided into plant and chemical types. The characteristic of the plant is that it does not harm the body, but its disadvantage is that it has a single color. Chemical hair dyes cause serious pollution and damage the blood system. Plant-based hair dyeing has been gradually accepted by people, and there are more and more institutions promoting and researching plant-based hair dyeing.

Chemical hair dyeing changes the structure of the hair itself and corrodes the scalp. Ammonia corrodes and damages the hair follicles. Plant hair dyeing is a physical process, and the nourishing elements adhere to the hair and scalp like a film, nourishing and caring for the hair and nourishing the hair follicles. Just like an oxide film will form on a cut apple, plant-based hair dye uses the physical oxidation process to make the nourishing ingredients adhere to the hair and scalp.

Injury Prevention

With the continuous improvement of the quality of life, people pay more and more attention to appearance. Walking on the streets, it is not difficult to find that hair dyeing, especially color hair dyeing, has become a consumer fashion. According to the requirements of consumers, it can be dyed in many colors: grape red, brilliant purple, wine red and so on. The purpose of hair dyeing is to be beautiful, but do you know how much harm there is behind this beauty?

Damage Type

Firstly, oxidants are an important component of hair dyes, which have a considerable destructive effect on hair keratin and can easily cause damage to the hair. Frequent use can make hair dry, brittle, split, and easy to fall off.

Secondly, most permanent hair dyes use aniline dye intermediates, which are among the most irritating and toxic among cosmetic raw materials. No wonder some people experience allergies on the outside of their hair, around their ears, on their scalp, and other parts of their hair when dyeing their hair, and even experience symptoms such as dizziness and nausea.

Thirdly, hair dye is composed of two ingredients. When using, they should be mixed first and then applied to the hair. However, a chemical reaction occurs at the moment of mixing, producing high concentration of harmful gas - dioxin. Dioxin is a strong carcinogen recognized by the World Health Organization. It enters the body through the respiratory tract and remains in the muscles for a long time and is difficult to decompose. It interferes with the human endocrine system, and both estrogen and thyroid hormones are disturbed. Long-term exposure will lead to genetic mutations and deformities in the human body, and induce cancer and other diseases. Therefore, it makes scientific sense for women who are pregnant or planning to become pregnant not to dye their hair.
