Middle-aged and elderly friends who have been doing chemical hair dyeing for a long time should remember that these points should be known and benefited early.
First of all, don't dye your hair in an environment where the temperature is too high, there are many people who like to do chemical hair dyeing when taking a bath, because chemical hair dyeing is fast to color, and they want to use the bath time to dye their hair.
Second, if there is damage to the scalp, it is best not to dye your hair if you have a small pustule or a disease, and you need to wait for ** to dye it later.
Third, it is necessary to control the frequency of hair dyeing when doing chemical hair dyeing, which will damage the hair quality and easily cause problems such as hair loss. Even if you are healthy now, you should also pay attention to controlling the frequency of hair coloring.
Fourth, the preparation before dyeing hair, three days before dyeing, it is best not to wash your hair, so that the oil and dandruff secreted by the scalp can form a natural protective film on the scalp and hair follicles, reducing the damage to the scalp.
Fifth, the ingredients and formulas of each hair dye product may be different, so it is not recommended to mix different brands to avoid allergies.
Sixth, when doing chemical hair dyeing, try not to apply a large amount of dye paste and accumulate it on the scalp.
Seventh, when doing chemical hair coloring, remember that the dye paste stays on the hair for too long, usually not more than 45 minutes.
Eighth, when washing the scalp after dyeing, try to wash it several times repeatedly to remove the remaining chemical components from the scalp and hair follicles. Finally, it is recommended to prepare a bottle of post-dye detox cream to detoxify the hair, especially the scalp, after each dyeing. Next month or later, we can use the re-dyeing method to only dye the areas of gray hair and avoid repeating the whole hair every time.
