How long does it take for dyed hair to fade, and how long does it take for dyed black hair to fade

It depends on how long you've been dyed, what color you're going to have, and what kind of perm you're going to use, as these all determine whether or not the dyed color will fade.

Before we know how to protect color, let's take a look at why hair fades. <>

Because color is dyed on the hair, not on the surface, which is a complex chemical process, we should start with the principle of dyeing hair。The process of dyeing hair is to make use of oxidation.

Hair dye is used to remove natural pigments from the hair, after which artificial colors are added to the hair to give the hair the color it receives. How much natural pigment is removed determines the shade of hair color. After the natural pigment is removed, holes form in the hair.

When dyeing hair, artificial colors fill these cavities, but artificial colors are less stable. When the hair is exposed to heat or some chemical components, the structure of the hair is temporarily altered, which will lead to the loss of artificial colors. For example, using high-temperature hairdressing tools, or washing your hair with high water temperatures can cause color loss.

That's why hair fades. <>

If you dye your hair for more than a month, it won't matter when you have a permanent wave because the color has stabilized and the floating color has been washed away. If you just dye and then perm your hair, it will have an effect regardless of the color.

However, fading is mainly floating, and the color that enters the hair is difficult to come off. When softening or applying No. 1 agent, you will see the color oozing, but you will not see it after washing it off, and the maximum effect will not exceed the color of the degree.
