How to choose hair dye is safer?
The harm of hair dye, I believe many people will hear, but they are not too clear. They do not have a correct understanding of the real harm of hair dye.Pimples, pimples, blisters, blisters, exudation, erosion, crusting, crusting, thick, rough, capillary dilatation, skin atrophy, pigmentation, etc.Today, the quality of hair dye in the market is uneven.So, how to scientifically choose hair dyeing agents is safer?
There must be a regular production batch number
The regular hair dye has a production batch number. The safety of the Ministry of Health has been evaluated by the Ministry of Health and obtained the approval number of the special use cosmetics of the Ministry of Health of the Ministry of Health of the Peoples Republic of China.And with a sanitary license approval number, products without the above batch number are illegal products, and consumers should not buy it.
Try to buy well -known brands
At present, there are many manufacturers of hair dyes and a variety of brands. Some small -scale manufacturers may have some problems in terms of quality control.Try to buy hair dyeing supplies for well -known brands of large manufacturers.
Requesting relevant documents
The Ministry of Health of my country has formulated the "List of Hair Dyeing Earnoma (Trial)" to standardize the quality of raw materials for hair dye products and ensure the safety of dyes to the greatest extent. Regular manufacturers will strictly use phenyleneramine in accordance with this regulation.The formal manufacturer should have the number of cosmetics approval texts of the Ministry of Health. It is recommended that consumers ask for a copy of the approval when purchasing products.
The identifier is clear and complete
To buy hair dye, you should go to a regular large shopping mall or supermarket. It depends on whether its packaging is complete when purchasing. Do not buy incomplete.The product logo should be clear. In addition to the production batch number and hygiene licensing certificate number, the manufacturer, production address, product name, production date, safety warning, use guidelines, storage conditions meet the shelf life and safety requirements of the productclear.
Differentiated hair dyes of different properties
At present, there are hair dyes extracted from natural plants in the market. These hair dyes are relatively low toxic, and the incidence of allergies is relatively low.The chemical hair dye contains phenyline, the effect is relatively good, but it is easy to cause allergies, and long -term use is harmful to the liver.Therefore, consumers should pay attention to the advantages and disadvantages when buying.
In addition, when using hair dye, we must pay attention to doing experiments before use, apply a small amount of hair dye behind the ears to see if there is a stimulating response, if so, we should avoid using it.Too much, you should minimize the number of uses or extend the interval time, which can also reduce the occurrence of skin inflammation.
The above is a little trick when buying hair dye. As a hairdressing person, I think these should be important, so you must pay attention to it.
