The principle of hair dyeing is to open the hair scales that protect the hair, remove the original color of the hair, and add the color of the hair dye. Therefore, when choosing the color of hair dye, Tian Hongyu's suggestion is that the target color can only be 3 degrees lighter than its original hair color at most, otherwise it will cause great damage to the hair. If you want to pursue a lighter color, it is best to dye it several times, and the interval between each dyeing is more than 1 month and a half.

Make sure that the hair is clean before dyeing, and there can be no styling products such as mousse and hair gel. And perm must be a week apart before dyeing your hair. Allergic skin should be tested for allergies.

When washed with too cold water, impurities in shampoo and conditioner will be locked in hair scales, and the hair will become hard over time.
13, when choosing shampoo, try to choose gender, otherwise alkaline shampoo will easily make hair fade. In hair dyeing products, the brighter the color, the easier it is to decompose. Alkaline shampoo will make the unstable red color fade more seriously. Hair conditioner is acidic, and it is easy to fade when used too much, so you should also buy a hair conditioner specially designed for dyeing hair.
