- Applying a semi-permanent hair color after keratin treatment is a very good idea.
- Semi-permanent hair color doesn’t contain ammonia and isn’t applied with a developer, and it won’t remove the effects of the keratin and your hair will have an even color.
- Ideally, you should wash your hair three days after keratin. Then, apply the semi-permanent hair color. This way, your hair will finish absorbing the keratin, and you’ll have frizz-free and healthy hair with vibrant color for longer.

You don’t know if you can apply semi-permanent hair color to your hair after the keratin treatment.

Considering that list, you look at your hair in the mirror. Even though you feel happy because it’s frizz-free, smooth, and shiny, your gray hair or roots ruin the look.
Or maybe you had an appointment where you wanted to surprise everyone by wearing your hair straight in a special color, like blue for example.
You can leave the grumpiness and impatience aside.
It’s a great idea to dye your hair with a semi-permanent hair color after your keratin treatment!
Yes. I’m not crazy. And now that you’ve got your smile back, I’ll tell you why you can dye your hair with a semi-permanent dye after keratin.
What’s the advantage of dyeing keratin-treated hair with semi-permanent dye instead of permanent dye?
The advantage is almost obvious.
Semi-permanent hair dye doesn’t contain ammonia and isn’t applied with a developer. Therefore, it doesn’t penetrate the hair core.
It’s simply a film of color, which is deposited on the outer layer of the hair. As it doesn’t penetrate the hair core, it can’t interfere with the keratin treatment, which acts on the innermost layer of the hair.
However, things change radically if you want to apply a permanent dye after keratin.
In that case, you should wait at least fifteen days to do it. The permanent dye penetrates the hair shaft and opens the cuticles. Therefore, part of the keratin would be lost due to the permanent dye chemicals.
That being said, I know that one question dominates your impatient mind.
How long to wait to dye hair with semi-permanent hair dye after keratin?
As a professional colorist, I recommend you wait three days to color your hair with a semi-permanent hair color after the keratin treatment.

Semi-permanent hair dye may last longer on keratin-treated hair
Keratin repairs both the outer and inner layers of the hair. When manufacturers of semi-permanent hair dyes talk about color durability, they refer to healthy hair, and your hair is healthy because you applied the keratin treatment!
Now, let’s not fool ourselves.
Aftercare is also important. If you flat iron your hair every day or wash it four times a week, the color won’t last long.
Remember that semi-permanent hair color gradually fades with washes.
So, ideally you should wash your hair up to three times a week. This way, you’ll extend the color’s duration and the keratin treatment’s effects.

You can apply a semi-permanent hair color three days after the keratin treatment. At that time, you can wash your hair to remove any dirt and leave your hair clean for semi-permanent coloring.
