As you can see, if you want to dye your hair a week after getting a perm, it’s essential you choose correctly the type of dye you will use.
Because if you dye your hair a week after a perm using a permanent hair dye, you will ruin the process you applied. In other words, you can kiss the perm goodbye and, with it, your glorious curls.
And I’m guessing that’s not what you’re looking for after paying a small fortune at the salon for your perm.
Why can’t you use permanent dye a week after a perm?
Because the permanent dye contains ammonia, and you apply it with developer. That’s how it can penetrate the inside of the hair to change its color.
And by penetrating the inside of the hair, would remove some of the perm liquid still working on the inner layer of the hair.
So when you apply treatments such as a perm to your hair, the first few days of care are essential for the perm to last.

If you color your hair with permanent hair dye a week after a perm, two things could happen:
- If you have very pronounced curls like ringlets, they will lose their shape, stretching and transforming into waves.
- If you have chosen a softer wave for your perm, there will be nothing left of the waves.
Therefore, if you want to dye your hair with a permanent dye after your perm, you should wait at least two weeks. That’s the only way the dye won’t ruin the shape of your curls.
Now let’s say you can’t wait two weeks to dye your hair after perming it. Maybe you can’t stand your gray hair. Or perhaps you don’t like the color difference between your roots and the rest of your hair.
Is there an alternative to dyeing your hair a week after your perm without damaging your curls? Yes, and that’s what I’ll talk about now.
One week after your perm, you can color your hair using semi-permanent hair dye
Why? Semi-permanent hair dye doesn’t contain ammonia, and you don’t apply it with developer. So it won’t penetrate the inside of the hair, which is where the perm liquid sits.
This type of dye forms a color film on the outer layer of the hair. That means you can use it on your permed hair without any risk.
So, to be clear, you can use a semi-permanent hair dye a week after your perm. You can even apply it just 48 hours afterward if you like. It won’t alter the shape of your curls, and you will still get the color you want.
One week after your perm, you can only use a semi-permanent hair dye to color your hair. Because if you apply a permanent dye one week after a perm, you will ruin the shape of your curls, or they will disappear.
