Take off your hairWhite hairThese are the “first things” that bother many. As a result, hair products such as black hair and hairproof hair are popular. During the previous period, many consumers in need of a solution to their hair problems had been moved by the announcement that “80-year-old white hair, no dyed hair, just a bottle of shampoo”, “3 days black, no recurrence”, “state file, health effectiveness”. In fact, there is a long-standing mystery about whether shampoo can be black, but one cannot resist the temptation of so-called technology。
So, is there really a shampoo that can be dark
The shampoo's mostly mild
It only helps improve the quality of the hair
A search by journalists using the key word “black shampoo” revealed a wide variety of related black shampoo products on the electrician platform. Some are marked with the word “root”, which says that it cures white hair and does not recur. There are those who say "black when washed" and "natural permanence". Some products are also known as “99 per cent of users successfully blacked out”, which applies to white hair generated by any cause。
So, what is the principle through which these shampoos, known as black and white, work? This is explained in the presentation of a number of products, since the active components contained in shampoo can be nourished by providing hair capsules, deep-activated restoration of damaged hair capsules and re-emergence of melanoid cells, so that black hair can come from the head of the hair. The product even claims to be pure plant extraction, free of hormones and without any side effects. So, how does it work? Looking at the product evaluation appearance is more favourable, but there are netizens who question that “blacking is impossible” “in two months, my hair is still white”。
Many members of the internet would ask if the product page clearly indicated that the dea had written it, and that was not a letter. Special investigations have been conducted by the media on such products, and four of the six businesses surveyed that claimed to have a nda file number were classified as non-specialMake-upScope; only one has provided a registration number for special national cosmetics, but in the column headed “remarks” it is clearly indicated: “this instalment is not intended as a product claimsEffectivenessThere is also one that does not have a registration number。
In the 2007 edition of our cosmetic health code, nine types of cosmetics with hair-bearing, dyeing, hair-burning and hair-dressing effects are referred to as special-purpose cosmetics. The state regulates them more closely than ordinary cosmetics, which are produced and sold only after strict approval and approval by the state regulatory authorities. In addition, the national drug supervisory authority has sent a reminder that the application of everyday chemical products, such as skin, hair, nails and lips, for the purpose of cleaning, protecting, beautifying and polishing the surfaces of the human body, is a mild and auxiliary function and that consumers should be rationally treated for propaganda that is exaggerated, explicitly or implicitly medically or inflammatory。
There is no effective way to improve it. White fire
Some netizens say that some shampoo products do have the effect of blackening hair. In response, chen sheik, chief of dermatology at beijing university's 1st hospitalCopeAccording to the article, shampoo, which says that it is possible to gradually black out white hair, also containing the key ingredient of the dye, is only used for a shorter period than traditional dyes, and for a shorter period of continuous dyeing. If the patient is allergic to the dye, it is also allergic to the shampoo and is not black。
In normal conditions, white hair begins to decline when humans grow older, and the tissue of the body becomes difficult to meet the need to produce black particles, leading to a gradual reduction and the emergence of white hair. Young people have white hair for a number of reasons
One is genetic。
Second, chronic diseases, such as tuberculosis, chronic colonitis, etc., are prone to undernourishment of the body and to malnutrition of the hair。
Third, excessive brain use, with young people in a chronic state of over-brain use, can make their brain highly nervous and stressful and accelerate hair from black to white。
Fourthly, malnutrition, the lack of proteins, vitamins and some trace elements make hair white。
In addition, drinking alcoholic beverages is also prone to long white hair。
So, is there any special effects that can make white hair black
In an interview with the media, u wenju, deputy director of dermatology, wahshan hospital, university of jordan, stated that blackening white hair was not possible if black cells did not exist or were small. Moreover, it was not to be expected that all white hair would turn black, and there was currently no clear way in the world to black it. It is also stated in the scientific literature of the chinese association of science and technology that so far there is no precise method of treating white hair, nor is there a special treatment for white hair。
Early hair should identify the cause and treat the symptoms
When hair grows, there is no good way to black out the white hair that has been generated, except for the dye. It is important to prevent and actively treat primary diseases with white hair, first by going to a doctor to determine the causes of their own white hair and then treating it as soon as possible。
With regard to the prevention of early birth, yang lili suggested that these should be done:
1. Pay attention to the regulation of diets, in preference to foods rich in vitamins such as groceries, beans, vegetables and fruits, and to the liver, tomatoes, tomatoes, potatoes, spinach, and high protein foods such as peanuts, eggs and so on。
2. Early and white hair does not mean that there is no need to be worried about it, but that peace and harmony should be maintained, spiritual well-being and harmony should be avoided, and emotional stimulation and stress should be avoided. In order to reduce the generation of white hair, it is first necessary to remain happy and relax。
3. To develop a healthy lifestyle, to develop a good habit of rational use of the brain, to sleep early and not drink alcohol and not stay up late. These also contribute to reducing white hair generation。
4. Actively treat chronic diseases and remove barriers to the formation of black particles。
In addition, there are three points to be taken into account in the use of dyes
First of all, learn to select dyes and, as far as possible, products that are least harmful to the human body。
Second, the skin sensitivity test must be performed before the hair is dyed, by putting a dye on the back of the ear or on the inside of the upper arm, observing for three days whether the skin is showing signs of redness, allergy, etc., and, in case of discomfort, immediately stopping the use of the product and visiting the hospital in a timely manner。
The third is that the frequency of hair ironing should not be frequent, preferably every three or six months。
