Speaking of hair coloring first of all let's understand its composition, generally speaking, hair dye can be divided into three categories: plant hair dye, semi-persistent hair dye and persistent hair dye. When it comes to this, I believe you should be able to see which one is more effective, but the more effective it is, the more harmful it is. The best thing about the so-called long-lasting hair dyes is that they can be dyed in a variety of colors, and they can also completely cover up the original color of the hair, so this type of hair dye does make the hair color stay longer. However, the process of dyeing this type of hair is very complicated, first of all, you have to bleach the original hair color into white, since bleaching into white, it proves that your hair is completely "dead". And the customer dyed this must be regular hair color, and persistent hair dye contains PPD, this ingredient is extremely easy to cause skin allergies, so we still need to be careful to choose.
There is also a semi-permanent, the advantage of this is that it can increase the brightness and luster of the hair, but the time is not long, generally speaking, wash the hair 6-8 times the color will be washed off. The best of these three is the plant hair dye, because the plant hair dye is a natural product extracted from plants, it only dye surface layer, will not enter the hair, but the bad side is that for people with gray hair, this can not play a role. Hair coloring is generally best not to be done more than four times at a time, and too much of it can make your hair dry and lack luster, and it can also make hair loss worse. The most important thing is that hair dye contains carcinogens that are harmful to the human body and are likely to harm the body.
