Semi-Permanent Dyes: what Are They and How They work

Semi-permanent hair dyes are dyes that last only 4 to 6 weeks, so the color usually fades much sooner than permanent dyes.

The reason behind the short life spam of permanent hair dyes is because they are made without ammonia and peroxide which are two key chemicals for color longevity.

Do I have to Bleach my Hair to use a Semi-Permanent hair color?

Dark hair:

Light to Medium Hair ( light brown or blonde):

What Happens When the Dye Color Fades?

You might be wondering if your original hair color will pop back when the dye fades out, it might but it will take a long time and the reason behind that is as follows:

The second reason is that before your original color comes back there is a long period of fading that will take place. The color you chose will fade into lighter and lighter colors leaving a tint behind it.

Its important to note here that if your original hair color is bright then the tine will take longer to get washed away completely.
