How long does it usually take to dye your hair?

Hair dyeing has become a very common thing in human life now, because hair dyeing can help our hair achieve the desired effect and at the same time improve our image. Hair dyeing is very good, but the dyeing time is best to be about 40 minutes, because this can keep the hair color longer.

How long does it take to dye hair normally? Does heating or not have anything to do with the color and hair quality?

The principle of hair dyeing is the same as hair care. In the early days, barbershops had to heat the hair when dyeing it. As time went by, consumers had forgotten why it was necessary to heat it. In fact, there is no need to do this. After being heated, the hair cuticles are opened. If you wash your hair at this time, the dye or conditioner will be lost all at once.

Therefore, to have a good effect, just let it sit. Inside the salon, there are more weird ideas. Some people say that hair needs to be wrapped in plastic wrap after dyeing to maintain the color; others say that hair needs to be loosened for customers, believing that the more contact with air the hair has, the better it can be dyed. Basically, these have no scientific basis. Because the plastic wrap will concentrate the temperature of the scalp, the color at the roots will tend to be too bright.

However, the method of picking loose pieces does not actually help the process of oxidation and discoloration. The best way is to let it sit, so just let it sit. As long as you grasp the staying time accurately, 40 minutes is 40 minutes. Don't discount it or increase it smartly. Then the dyed color should be what you originally envisioned. If not, you should recall the color adjustment process or the color mixing technique. It is best to avoid adjusting the standing time arbitrarily without knowing the reason, as this may not necessarily improve the results.
