01 First of all, we recommend that it is best to buy branded hair dye in regular stores, because there are too many fakes, and we need to buy them from regular channels to reduce the chance of buying inferior hair dyes.

02 Secondly, the outer packaging of ** hair dye should have an approval number for special-purpose cosmetics, and those without an approval number are inferior hair dyes.

03 Then there must be instructions and precautions in the packaging of hair dye, and it will prompt you to do ** test before use, if you don't have it, it is an inferior hair dye.

04 Finally, the hair dye must be labeled with the ingredients, and the content of p-phenylenediamine must be within 6% of the total content, otherwise it is an inferior hair dye.

1. Chinese stickers.

Schwarzkopf is a foreign imported brand, and China clearly stipulates that imported goods should be labeled in Chinese on the outer packaging. Similarly, genuine Schwarzkopf products have a Chinese label on the outer packaging, and the font size of the label is moderate, only the bottom net content font is larger, and the handwriting is clear. The country of origin, manufacturer and importer are also indicated on the label, and the address of the importer is also clear.

Counterfeit Schwarzkopf is generally labeled in German or English, and although some goods are labeled in Chinese, the handwriting on them is blurred, and the importer is not clear. Some even get the net content units below wrong.

2. Packaging. Schwarzkopf** does not have a box, but is protected by a professional wine-grade bubble bag. Imported Schwarzkopf is naked, without other boxes such as packaging boxes. The imitation one generally comes with a paper box.

3. Inkjet coding. We also have to look at the product coding of the bottle or the bottom of the bottle, in general, the 1st and 2nd represent the manufacturing concession area, the 3rd and 4th represent the day, the 5th represents the month, the 6th represents the year, and the 7th-10th represents the production batch. By comparing the consistency of the inkjet code and the Chinese label, we can distinguish the authenticity of Schwarzkopf.

As shown in the figure below, Schwarzkopf's production information is: Germany, production date June 21, 2012, production batch 6001.

4. Fragrance. The fragrance of Schwarzkopf** is mainly light and elegant, giving people a more comfortable feeling, and generally does not appear pungent or unpleasant smell. Now, although some high-quality imitations are close to the original Schwarzkopf in appearance, the smell is strong and a little pungent, giving people a feeling of discomfort, and some will feel dizzy after smelling for a long time.

5. Effect. Schwarzkopf products focus on the care effect of the hair, and the same is true for shampoos, which are generally more targeted, and the hair is smoother and shiny after use, which can effectively regulate damaged and dry hair. However, it is difficult to achieve the effect of genuine products due to the different raw materials of production.

We don't feel any noticeable changes in our hair after using it, and that's probably a Schwarzkopf imitation. Tan trailed.

In fact, for plant hair dye, I believe that many people are both happy and hesitant, pure natural and harmless plant hair dye really earns enough eyeballs, but for this kind of hair dye products, we will also be rational and skeptical. Although it is difficult to choose a truly natural and harmless plant-based hair dye, we still have to keep our eyes open when shopping.

1. Look at the ingredients. Since the crude plant hair dye is pure and natural, then we have to find out if there are any chemical ingredients on these hair dyes, and some hair dyes containing phenylenediamine, phenols, amino acids and peroxides such as hydrogen peroxide can be eliminated.

2. Meow plant ingredients. The plant hair dye contains ingredients such as schisandra, avocado fruit, and Polygonum multiflori, which proves to be more credible. However, if it contains henna vegetable dyes, angelica, coumarin and other ingredients, this kind of plant hair dye is actually not safe.

For example, Angelica dahurica is a strong photoallergen, which can easily cause photoallergies when eaten or applied externally, and it is forbidden to add coumarin to skin care products.

Natural Village Hair Dye does not contain benzene dyes, and it can make plant pigments dyeing quickly and fastening the color, and you will not lose color when you wipe it with a white towel just after dyeing, the product is really good.

1. Whether it is a regular manufacturer, whether the enterprise qualification of the factory manufacturer is complete, and whether the test report and national cosmetics of the product are available.

2. If there is a well-known large company supervision or technical support, it is better, after all, the products of large companies have been operating in the market for a long time, which is a guarantee of quality.

3. Looking at the time of hair dye, the longer the better, but it is definitely not that you can turn black by combing it casually.

4. Look at how long it has been on the market, and the time it has been circulating in the market is the most powerful test for a product.

To be honest with you, hair dyes are all harmful and bad. If you have to dye it, find a professional barbershop.

What to see? Look at the form! At present, basically all chemical hair dyes are in the form of pastes, while natural pure plant hair dyes are only in oil and powder form.

When you buy a hair dye and find that there are two tubes of toothpaste-like old deficiency paste inside, then it must be a chemical hair dye. 2.Smell chemical hair dyes have a pungent smell, while natural hair dyes have a light fragrance and calm.
