Washing black is actually a kind of hair dye. It is usually not black. CCTV exposed five types of black washing containing carcinogens. The carcinogen p-phenylenediamine is marked in the ingredient list of many black washing products on the market. Some products are not labeled, but many brands of black shampoo actually contain p-phenylenediamine, and even carcinogenic, mutagenic and teratogenic substance "m-phenylenediamine" without labeling. This has been exposed by CCTV.
I still advise you to dye your hair less. However, for those who need work or are young and bald, they can choose to wear hats and wigs. If you must dye your hair, please try to choose plant hair dye. It is said that Uighurs in Xinjiang like to dye their hair with nail pollen. Nail powder is what we call henna, which was used to dye nails when I was a child. It takes six hours to color this pure plant dye. Don't trust products that claim to be pure plants and have a short coloring time.
In 2020, Tiggo ranked first in the list of top ten brands. But I looked it up online, and it was all spit. My own hair dye is the pollen protection of Impatiens balsamina. The ingredient list shows pure plants. It is very convenient to use. Make a paste with water, apply it to your hair and leave it for about three hours to wash it off. But there is also a disadvantage, white hair can be colored, black hair can not be colored, and the color is relatively red. I usually choose to go to a professional plant hair dye shop to dye my hair. This product is bought in the store I often go to, and sometimes I dye the newly grown hair roots myself. I hope I can help you.
Remove the white hair and wash it black. Be careful not to brag. Choose this one!
I really don't know. I haven't used it. But I don't recommend this method. Always feel bad about your scalp. You might as well buy a wig that suits you.
Washing black is not healthy. You can see the composition of the product. Basically, the two doses contain aniline chemicals. In fact, it is no different from chemical hair dye, but it is more convenient to use.

Thank you for inviting me! I'm sorry, my answer must have disappointed you. I am an old man with white hair in his early years. Before I retired, I dyed my hair several times a year and used a blackened hair dye, but I didn't find any good or bad impression. At this point, after retirement, I have lost all my hair and become a real white-haired old man [like] [covering my face]
My hair was a little yellow since I was a child, and now it turns white again, but I never thought of changing it by dyeing it. Let nature take its course [laugh].
