* Hair grows from the root: The dye only affects the hair shaft that's already grown out of your scalp. Your natural hair color is determined by the pigment-producing cells (melanocytes) in your hair follicles, located beneath your skin.
* New growth: As your hair grows, the new hair emerging from your scalp will be your natural color.
* Time: The amount of time it takes for your natural hair color to fully return depends on:
* Hair growth rate: On average, hair grows about half an inch per month.
* Hair length: The longer your hair, the longer it will take for the dyed portion to be completely replaced by natural hair.
* Dye type: Permanent dyes will take longer to grow out completely compared to semi-permanent or temporary dyes.
* Cut Dyed Portions: The easiest way to get rid of dyed hair is to cut it off as it grows out.
In summary: Dyed hair doesn't change the color of your future hair growth. Your natural hair color will always return as your hair grows, eventually replacing the dyed hair.
