Are plant-based hair dyes good?

Many people who love beauty often go to the barber shop to change their hairstyles. Many people like to dye their hair. Some people do it for beauty, while some people have to dye their hair because they have white hair. There are a lot of hair dyes on the market. In recent years, plant hair dye has become popular. Literally speaking, plant hair dye is extracted from plants. So is plant hair dye good or not?

Plant-based hair dyes are not necessarily pure plant-based. Currently, many plant-based hair dyes actually only contain plant extracts, but they are still mixed with chemical ingredients, so they can only be considered compound plant-based hair dyes. However, there are also many truly pure plant-based hair dyes, such as Yunsuo's henna powder. Compared with other compound plant-based hair dyes, henna powder takes longer to color and has a single color, but it is safe and healthy, and can nourish the hair. At the same time, hair dyed with pure plants is very natural and shiny, which is the biggest difference between plants and chemicals.

Various hair dyes contain dozens of chemical ingredients. According to tests conducted by relevant departments on more than 100 types of hair dyes, nearly 90% of them contain toxic chemicals such as nitrobenzene and aniline, which are easily absorbed by the skin and cause harm to the human body. Medical experts point out that if hair dye is used for a long time, as long as 1% is absorbed into the human body through the skin, it will accumulate and cause poisoning. The chemical substances will combine with certain cells, damaging the deoxyribonucleic acid in the cell nucleus, causing cell mutations and inducing skin cancer, bladder cancer, leukemia, etc. Therefore, experts warn to be vigilant about "diseases entering the body through hair."

How to reduce the harm of hair dyeing

Avoid permanent hair dyes. According to expert statistics, nearly 90% of hair dyes contain toxic chemicals such as nitrobenzene and aniline, which are harmful to the human body. To determine whether it is a permanent hair dye or a temporary hair dye, you need to see whether the color fades within 3-4 days after dyeing. If the color fades within 1-2 days after dyeing, it is a semi-permanent hair dye. If the color starts to fade or does not fade after two weeks, it is a permanent hair dye. The darker the color of the permanent hair dye, the more harmful it is to the human body. 48-hour skin test Although hair dyes are rigorously tested, in order to protect your hair, we need to conduct an allergy test before dyeing your hair.
