To dye black hair, look below.
It is better to dye it three times at first. It didn't work very well the first time. Heat with an electric heating cap.
White hair: Use edible natural hair dye.
In Minnesota, USA, a research team made a survey, and the probability of leukemia among local people who dyed their hair was 14 times that of people who didn't. Some people in China have also done relevant surveys, and the probability of leukemia in people who dye their hair is 3.8 times that of people who don't dye their hair. There is a woman in Beijing who has been going to the hair salon to dye once every three months since she was 16 years old and has been doing it for more than ten years. Last year, I was diagnosed with leukemia and learned that it was a leukemia related to hair dye.
As we all know, chemical hair dyes not only harm hair and induce asthma and allergies, but also induce malignant tumors related to hair dyeing. Leukemia occurs in the blood system and easily induces gland tumors, such as breast cancer, lymphoma and bladder cancer. ...
See how chemical hair dyes are harmful to health.
Cao Mei, director of dermatology department of Beijing Chaoyang Hospital, pointed out in an interview with TV that chemical hair dyes mainly dye hair through chemical reactions between substances. Many elements must be used in this chemical change-
First of all, there must be p-phenylenediamine or phenylenediamine, which is an intermediate coupling agent and has a strong adsorption capacity for protein (hair is 90% keratin). It is one of the basic components of hair dye, and it is recognized as a toxic chemical component, which may induce gene mutation in blood system, especially hematopoietic stem cells, and may cause tumor problems.
Second, the color-developing coating agent contains hydrogen peroxide. Hydrogen peroxide, commonly known as hydrogen peroxide, is suitable for disinfection in medicine. It is more alkaline and has a fluffy effect on the head. After the hair is fluffy, the gap between cells is large, which makes it easier for other colorants to immerse. The scalp is too strongly stimulated by this alkaline substance, which is easy to cause problems such as dryness and itching.
In the mixing process of 1 and No.2 chemicals, there is another aromatic amine compound, which will not only cause blood system diseases, but also dry the scalp and make the hair lose its original sulfur component (desulfurization), so as to facilitate the next chemical reaction and make the hair lighter, brittle and broken. ...
Using nail pollen as natural hair dye
Professor Cao reminded that the existing hair dyes in China are divided into chemical hair dyes and plant hair dyes, and the former is more complicated. Although the latter contains only plant components, its main component is chemical components, but it can nourish the scalp and reduce the stimulation of chemicals on the scalp. Therefore, consumers are advised to choose hair dyes containing plant ingredients. If you have time, you can also choose a natural hair dyeing product-henna hair dyeing.
Director Cao Mei said that nail pollen, as a natural pigment, is stable in nature, and the dyed color varies according to the hair quality and the time is different. Dyed on black hair is still black, but dyed on white hair is red or reddish brown. Experts' colleagues have dyed it with this powder. The parts that used to be white hair look bright and soft, and the whole looks like fashion highlights. The disadvantage is that dyeing is slow, and it needs to be applied with a hot towel for 4 to 6 hours.
If you are allergic to pollen, you can do a skin test first. When dyeing, it is best to use boiled water or warm water (it is better to add mulberry water or hot black tea or hot coffee), and mix 100% pure plant nail pollen evenly to make slurry. Adding the right amount of honey will make the hair smoother. Add black tea to make the color reddish (can be omitted); Add coffee to make it dark brown and less red (not necessary); Add 5 ~ 9 drops of lemon juice to fix the color. Don't wash your hair with shampoo immediately after dyeing, so as not to affect the dyeing effect, just use conditioner. This kind of powder is sold in hair dye shops, cosmetics shops and specialty stores in Xinjiang, with prices ranging from around 20 yuan to above.
Five kinds of Chinese medicine powder make white hair black.
Indigo Naturalis: It can play the role of coloring and is generally ground into powder. Its composition is 5% ~ 8% indigo, which can be used as a dye for clothes and a pigment for painting.
Ginger: In dermatology, it can cure ghost shaving (alopecia areata), and has the effects of warming hair, expelling wind and cold, promoting blood circulation and removing blood stasis. The method is to directly rub ginger slices on the affected area, three times a day, and increase the severity as appropriate.
Polygonum multiflorum Thunb: Polygonum multiflorum Thunb is divided into Polygonum multiflorum Thunb and Polygonum multiflorum Thunb. The main function of Polygonum multiflorum Thunb is to moisten the intestines and relieve constipation. The method is to grind Polygonum Multiflori Radix, Fructus Cannabis and Semen Sesami Niger into powder, and take 10g each time, three times a day. This is actually the main prescription of Maren Runchang Pill. Radix Polygoni Multiflori Preparata can blacken hair itself, and can increase the hematopoietic function-smooth blood flow, thus better caring for hair.
Gan Song: Dispelling wind and cold has an aromatic effect on hair dyeing. The taste of this traditional Chinese medicine hair dye is mainly its taste.
Bletilla striata: The roots of plants are rich in amino acids and protein, and the gum contained in them has certain viscosity, which can fix the color and make the hair dye more easily attached to the hair.
These medicinal materials for dyeing hair are easily available in pharmacies and can be selected according to the length of hair. For short hair, each of the five materials is 10g, and for long hair, 20g. Put the five materials (dry) together in a grinder to grind (fine), add a liter of water, then put them in an iron pot to boil (add iron and copper to the hair), and finally boil them until they are thick, and stir them every once in a while to avoid sticking to the pot. After that, apply hot compress to the hair for more than half an hour. After a long time, the effect will be better and the hair will be black and shiny. Calculated by 10 gram, the five Chinese herbal medicines add up to more than ten yuan. The price is not high, but the effect is good. After use, there will be no itching, allergies and other reactions.
