Consumers should pay attention to the following points when choosing black hair shampoo.

First, you should not dye your hair too many times, preferably no more than twice a year, and you only need to dye the newly grown areas. Rub some Vaseline on your scalp before dyeing your hair, and it's easy to wash off if it gets on it. 

Second, permanent hair color shampoo should be used sparingly. Consumers who use permanent black hair shampoo should consider switching to lighter-colored black hair shampoo. Generally speaking, those that fade when you wash your hair three or four days after dyeing are short-lived black hair shampoos, those that fade 1 to 2 weeks after dyeing are semi-permanent black hair shampoos, and those that do not fade for more than 2 weeks after dyeing are basically black hair shampoos. Permanent black hair shampoo. 

Third, do not dye your hair with different black hair shampoos at the same time. There is a possibility of a chemical reaction between black hair shampoo. Fourth, people who have sores, skin ulcers, and allergies to hair dye should not dye their hair. If you insist on dyeing your hair, you must do an allergy test, rub the black hair shampoo on the skin behind your ears, and if there is no abnormal reaction within two days, you can dye your hair. Fifth, after dyeing your hair, you should wash it several times, so as not to let black hair shampoo remain on your hair; when washing your hair, be careful not to scratch your scalp with your fingers.

It is necessary to check whether the production license number, sanitation license number, and approval number for special-purpose cosmetics are complete and whether the product implementation standard number is accurate. When purchasing imported products, you should check the hygiene approval number of imported cosmetics, the Chinese product name, the manufacturer's name, the address, and the name and address registered by the distribution unit.

What should I pay attention to when using black hair shampoo?

In the use of black hair shampoo, we should pay attention to the following points: 

First of all, before we use black hair shampoo, we still recommend doing an allergy trial experiment, that is, apply the cosmetics we are going to use on the flexed side of our forearm, that is, stay close to the elbow joint for some time. The specific stay time is based on the specific needs of our hair dyeing. 

For example, if it is dyed for half an hour, then stay for half an hour, and then gently rinse it off. Then observe for 2 to 3 days to see if there is any skin discomfort. If the skin is normal, then this black hair shampoo may be more suitable. If there is some redness, rash, itching, Tingling, and so on, then try not to choose such black hair shampoo. 

Secondly, when we use 5 mins speedy black shampoo to dye our hair, we should also pay attention that when we dye our hair, try not to apply this black hair shampoo to the scalp, because the adverse skin reaction of this cosmetic caused by black hair shampoo is contact dermatitis, which is a reaction after black hair shampoo touches the scalp, so when we dye our hair, try to keep a certain distance from our scalp. 

The third point, we can also take some protective measures. For example, when we dye our hair, we can apply some Vaseline or some cream to the hairline, which can play a role of isolation and prevent this black hair shampoo, when it touches the skin of our face, some adverse reactions occur. Last but not least, when we dye our hair, we should also pay attention to the residence time of the black hair shampoo. To achieve better results, some consumers just extend the dyeing time, which will increase the amount of black hair. The shampoo has the risk of causing this adverse reaction, so we recommend strictly following its instructions and properly controlling the stay time of theblack hair shampoo. Then, after dyeing your hair, you must also pay attention to the changes in the scalp. Once any scalp discomfort or rash occurs, you should go to the hospital for treatment in time.
