There are many reasons why dyed hair does not get colored. It may be that the hair is dyed before it is completely dry. In addition, if the coloring time is not enough when dyeing the hair, the artificial pigment is not fully oxidized, which will also cause the hair to not be dyed. In addition, it may be that the hair quality itself is of good quality, which makes it difficult for the cuticles to open during hair dyeing, and the hair dye is not easy to be absorbed. If the hair is waxed before dyeing, it will also affect the color effect.
