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."

Diseases caused by hair dyeing: 1. Skin allergic reaction is the most common adverse reaction of hair dyeing. Some people may not have an allergic reaction in the early stages of hair dyeing, but may have an allergic reaction after dyeing their hair several times. The longer the time, the higher the chance of allergy. 2. Cause changes in hair quality. The hair dyeing process will affect the moisture imbalance in the hair, and the denaturation and reduction of a large amount of protein. This causes the hair to become brittle, the fibers to break, and it loses its natural softness, toughness and shine. The more you dye your hair, the more damage it will cause. 3. Cause hair loss. The acute and chronic stimulation of hair dye can cause inflammatory reactions in the scalp and hair follicles, which over time can cause atrophy of the hair follicles, causing the hair to become thinner and eventually fall out. 4. Absorption of toxic substances damages liver and kidney functions. It is often found in metallic hair dyes and some synthetic organic hair dyes, such as those containing lead acetate, silver nitrate, benzene, naphthalene, phenols, etc.

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. Whether you are dyeing your hair by yourself from an over-the-counter brand or by a hairdresser, a skin test is required 3 hours before dyeing your hair. Drop hair dye A and B on the same point on the inside of your wrist, and then wait for the hair dye to dry naturally. If redness, swelling or itching occurs during the waiting process, it means that the product cannot be used. You need to take care of your hair before dyeing it. When dyeing your hair, the hairstylist will add some skin care ingredients to allow dyeing and hair care to be done at the same time. However, in order to ensure that the damage of hair dye to hair is reduced, hair care should be done 1-2 times 1-2 weeks before dyeing, especially for damaged hair. Hair care before dyeing can balance the slightly acidic scalp, increase protection for hair cuticles, and reduce the irritation of hair dye to hair. Avoid dyeing your hair repeatedly within three months because hair dyes contain bleaching agents, which can damage the hair cuticles and make them brittle and easy to break. If you dye your hair repeatedly within three months, it will cause serious damage to the hair that has not yet recovered, and the consequences will be disastrous. Dye your hair twice a year. If you want to maintain the effect of dyeing your hair, you can re-dye the newly grown part.
