Having beautiful black hair is a symbol of youth and beauty in the eyes of many people. Qizhen Wufa has captured consumers' love for beauty and advertised that its products are pure Chinese medicine and harmless "one-wash black" shampoo. All its products are nominally refined from herbs, which will turn black after washing, which will not only do no harm to the human body, but also make the newly grown hair black. Is it really so amazing? Or a lie? To this end, our reporter conducted an investigation.
Black when washed?
In order to find out the effect of exotic black hair, the reporter went to the drugstore designated for sale in his advertisement and found exotic black hair at a very remote counter. According to the sales staff of the drugstore selling exotic black hair, the usage of exotic black hair is the same as that of ordinary shampoo. It can be washed directly, and the effect is very good. Once you wash your hair, it will turn black. The reporter said that he was very confused and asked how it would be black after washing. Isn't this the same as hair dye? The salesperson explained that the product is pure Chinese medicine and definitely not hair dye. What is the principle of hair turning black instantly? The salesperson can't answer this question, just telling the reporter that the product contains traditional Chinese medicine, which will not cause harm to the body, and now there is a discount, so the price is very high.
However, the leaflet page of the product reads: "After using 3-4 boxes, my head is full of bright black hair, but there is no white hair. The most wonderful thing is that the scalp that had lost hair before grew new hair, which was black and shiny, and bid farewell to white hair. " When the reporter asked if the long hair could be blackened, the salesperson expressed uncertainty that long-term use might make the long hair blackened.
Sell products in the name of the country
At present, many products that can be washed black have been detected to contain "p-phenylenediamine" (carcinogen) hair dye, and even "m-phenylenediamine" (carcinogen, mutagenic and teratogenic) substance. Qizhen Wufa claimed that "this product is a black hair product with moisturizing effect approved by the national health department, not a chemical hair dye, and has no harm to the human body." The reporter inquired from the State Food and Drug Administration of the United States through the approval number "Wei Zhuang Te Zi (2007) No.0171"on the box. When registering, the product name is not Qizhenwu Letter, but Gao Yu Hair Cream (natural black). The product category is hair dye, and the product belongs to cosmetics, not drugs.
And the Ministry of Health specifically stated: "The Ministry of Health has not organized an audit of the claimed functions of the product, and this approval document is not regarded as an approval of the claimed functions of the product." However, Qi Zhen Ufa promotes it with the Ufa efficacy approved by the national health department.
Chinese medicine won't make hair black instantly.
Can the traditional Chinese medicine contained in rare black hair make the hair black?
This also needs a scientific explanation. To this end, the reporter interviewed experts in the field of traditional Chinese medicine treatment in Jiangsu Province.
Experts say it is impossible for traditional Chinese medicine to blacken hair within 10 minutes. Polygonum multiflorum Thunb, ginseng, black sesame and other traditional Chinese medicines do have a certain effect on blackening hair in medicine, but it takes a long time to get a certain effect, and all of them are taken orally, and the external effect is not obvious.
In addition, experts tell the public that the reason why people's hair turns white has a lot to do with age, and the loss of melanin in hair is the root cause of hair turning white. If the hair really turns white, it is impossible to make it grow black again through Chinese medicine.
