What color is the best for a few degrees of hair?

Many people may not know what color is suitable for hair, and the effect is the best. Today, I will talk about my experience: it is the most suitable and best to dye my hair purple between 4 and 5 degrees. Purple beyond 5 degrees is not straight, because the blue pigment contained in the hair itself has been withdrawn after 5 degrees. But purple is blue+red = purple, so the purple beyond 5 degrees should be adjusted, not very straight! Hair is most suitable for 6 degrees red, because the blue pigment has been removed, and the coverage of red pigment is stronger than that of yellow, so red is the most positive at that time. If the red color is below 6 degrees, it will be dark or purple, while the red color above 6 degrees is orange, because if the red pigment is removed and mixed with yellow, it will form red+yellow = orange. It is recommended that the red color above 6 degrees should be red! The reason why the hair is most suitable for 7 degrees orange is not mentioned above. The reason why the hair is most suitable for 9 degrees yellow is because the red pigment has been removed, so there is only yellow pigment in the hair. At this time, the most suitable colors are yellow and cool series, such as dark blue linen. Generally, those colors that are difficult to be purple and gray should be faded first, because the effect of covering red and blue with gray series is not obvious, so it is generally recommended to let those colors fade first!
