Can black hair shampoo really wash hair black

No.

The shampoo for white hair to black hair is not real, it is the same as hair dye, and it is still white after you wait to dye it, not that it will grow black after dyeing, it is impossible, because your gray hair is directly related to the body, not that your hair will grow black after dyeing it once, so you have to pay attention to distinguishing which ones are false advertising.

Tips for darkening your hair

1. Shampoo with milk and vinegar.

Adding vinegar or lemon juice to your shampoo and then washing your hair as normal can reduce breakage and make your hair more flexible. When your hair feels dry and wilted, you can use milk to shampoo and let the milk stay on your hair until it dries out, and although it smells a little unpleasant, the moisturizing effect is unexpected.

2. Use sunscreen to protect dyed hair.

Intense sun exposure is not only damaging to hair, but also a big part of fading color-coloured hair, so to avoid sun damage, mix sunscreen and distilled water in a 1:3 ratio and spray it on your hair before heading out. You can do a good job of sun protection for your hair.

Lion's mane mushroom is an excellent health food with high protein, low fat, rich in minerals and vitamins, and has high nutritional value. It also contains a variety of amino acids that are essential for the human body, and regular consumption is beneficial for good health. Lion's mane mushroom is also an excellent hair food and has a good effect on hair growth.

In recent years, there has been a black shampoo on the market, which is actually a hair dye that can darken the hair, but contains harmful chemical ingredients and is harmful to human health. Purported to be a natural plant-based "one-wash black" shampoo, it contains a chemical called p-phenylenediamine.

Phenylenediamine is a chemical dye that is a potential carcinogen and is currently permitted in the production of hair dyes, but there are clear restrictions on how much it can be used. According to China's "Hygienic Standards for Cosmetics", the content of p-phenylenediamine in hair dyes shall not be higher than 6%.

The content of p-phenylenediamine in a black shampoo is reached, but the frequency of use of shampoo is high and long-term accumulation, which can easily pose a threat to human health and safety, and it is illegal to add this substance to shampoo.

Whether it is a historical legend or a literary description, although it is a bit exaggerated, after all, it shows that people have long believed that the change from black to white hair is related to spiritual factors.

Poor nutritional status.

Hair is the appendage of the body, and it needs adequate nutrition like other organs and tissues in the body. Hair color varies depending on the race. The hair color of Caucasian people is golden, and the hair color of brown people is red and black, and we yellow people, because the pigment particles of hair contain copper, cobalt, and iron, so it is brownish-black If there is a long-term lack of copper, cobalt, and iron in the diet, these inorganic salts will naturally affect the synthesis of melanin, making the hair turn from black to white.

In addition, according to medical clinical observations, if the body is chronically deficient in protein, vegetable oil, vitamin B1

and other endocrine disorders, tuberculosis, typhoid, pernicious anemia and other wasting diseases.

Brain overkill. Studies have found that mental workers are in a high-pressure state for a long time, highly stressed, have no time to take care of physical exercise, coupled with unbalanced diet, bad lifestyle habits, etc., so they are prone to premature gray hair. So how to prevent gray hair?

A wash of black! Nothing new. The shampoo is infused with semi-permanent pigments, and the pigment is wrapped around the surface of the hair when you wash it, and the hair turns black after a few more washes.

Not only black, but also a variety of colors, you can choose this color shampoo according to the color you dye, and the color that has been dyed will fade slowly. To put it bluntly, it is semi-permanent hair dyeing.

According to the principle of hair dyeing, hair dyeing is divided into three categories: permanent hair dyeing, semi-permanent hair dyeing, and temporary hair dyeing.

1. Permanent hair dyeing: It is the only chemical hair dyeing technology in the world, which can remove the color of the hair itself, dye the artificial color to the hair, and let the hair change color this time.

2. Semi-permanent hair dyeing: This kind of hair dye is a wrapping type, and the pigment is wrapped in the scalp of the hair and will fall off with shampooing.

3. Temporary hair dyeing: Some sprays on the hair are pigments, which will be washed off. For example, colored hairspray and so on.

Shampoos are added to a semi-permanent color, which also falls under the category of hair coloring. The roots of the hair grow out of the original color, you have been using it for a long time, and the gray hair is slowly revealed. This principle has existed for decades, and it can be said that once it is washed black, it is not washed when it is not used (if it does not use pigment, it will fall off, and the gray hair will be exposed).

The concept is good, but don't confuse the public, when the concept of hair dye is fine, if it turns black with washing it is misleading. Some reports even say that it is natural, plant-based, non-toxic***, and can grow black hair, etc., which is a bit exaggerated.

The drug regulatory department is also opening an investigation. So, don't change your hair color with a black shampoo.

In barber shops, hairdressing equipment is generally used to accelerate such chemical reactions by means of high temperatures, light, etc. However, in this"A wash of black!
