* Permanent hair dye alters the structure of your hair. It uses chemicals like ammonia and peroxide to open the hair cuticle, allowing the dye molecules to penetrate and react with the natural pigment (melanin). This permanently changes the color of your hair shaft.
* The dyed hair will remain that color until:
* It grows out: The only way to get your original hair color back naturally is to let the dyed hair grow out completely and cut it off.
* It's chemically altered again: You can use other dyes or chemical processes to change the color again.
What you will see:
* Root regrowth: As your hair grows, you'll see your natural hair color at the roots. This is why people need to touch up their roots regularly when using permanent hair dye.
* Fading: While permanent dye is designed to last, it can fade over time due to washing, sun exposure, and other factors. This might reveal some of the underlying color tones, but it won't be your original hair color.
In summary: Permanent dye is a permanent change to the hair that has been dyed. The only way to get back your original color is to grow out the dyed hair.
