- Semi-permanent dye will wash out completely after at most 16 weeks because it doesn’t get into the deepest part of your hair cuticle like permanent dye does.
- Of course, you can always speed up the washing out process by using dish detergent for example.
- And if you want to make the color last longer, all you’ll have to do is use a sulfate-free shampoo with cool or even cold water.
I have a question: Why do you want to know if semi-permanent dye will wash out completely?
- Are you bored of your natural color?
- Did your dye not completely cover your hair the way you hoped it would?
- Are you itching to try another kind of dye?
- Did you dye your hair and you’re not happy with the color?
If you answered “yes” to any of those questions, then semi-permanent dye is right for you because it doesn’t change your hair’s natural pigment and it will fade as you wash your hair.
That means it will completely wash out eventually, but not immediately or even one day to the next. Depending on the brand of dye you use, semi-permanent dye can last 10-16 weeks.
If you dyed your hair using this kind of dye and you want the color to wash out quicker, there are a few tricks for making that happen, which I’ll tell you about in a minute.
But, I think it’s important that you know how semi-permanent dye works on your hair. These kinds of dyes are designed for people that don’t want to damage their hair with chemicals. They’re also the best choice if you decide to change your hair color for a short period of time.
Why do they wash out completely?
Because semi-permanent contain color molecules that get into the external layer of your hair and give it color. Since these dyes don’t contain either peroxide or bleach, the color is only able to penetrate the outermost layer.
That’s why they don’t affect your hair’s natural color and after many washes, none of the dye will remain. It will be like you never even dyed your hair in the first place.
Are you happy with the color you’ve ended up with thanks to your semi-permanent dye?
If so, then I imagine that you’ll want to make it last as long as possible and to do that, you must make some changes to your hair care routine.

How to get rid of semi-permanent dye faster
When you decided to dye your hair, many things might have gone wrong and maybe you ended up with a color you don’t like. Perhaps because it wasn’t the best color for your style or maybe you didn’t leave the dye in for long enough so the color ended up uneven.
The good news is that if you used a semi-permanent dye, then now you know that it will end up completely washing out. But, I have even better news for you: You can speed up the process to get rid of it even quicker.
- The least aggressive solution for your hair is to wait for the color to fade as you wash your hair. The more you wash it, the quicker the dye will fade.
Because the sulfates in the dish soap will strip the dye molecules and get rid of the color you don’t like.
You should use it just as you would your normal shampoo. And, if you want to get rid of the dye faster, wash your hair twice a day.
- Of course, the soap will take away the pigments in your hair but will take with it your hair’s moisture. So, I recommend that you do a moisturizing treatment at least once a week.
If your ends are what is very dry, use a few drops of coconut oil or micellar water on your hair. That will help reduce the damage.
- And don’t even think of bleaching your hair!
Because not only will you get rid of the dye, but you’ll also lighten your hair too, and if you don’t do it perfectly, your hair might end up with uneven color in certain areas or even worse, you might burn your scalp.
Now, let’s think about the flip side. Do you want to make your semi-permanent color last longer? If so, keep reading.
How to take care of your hair to make semi-permanent dye last longer
- If you like the color in your hair, and you want to avoid it washing out quickly, then the first thing you should do is watch how often you wash your hair.
Is your hair greasy and you’re not able to only wash it every two or three days? Well, what about dry shampoo?
It’s ideal for these kinds of situations because it will help make your hair bright and soft again, and it’ll make your hair smell clean, too.
- It’s also very important to pay attention to the temperature of the water when you wash your hair.
Try to always use cold water, or cool if you can’t handle cold, and sulfate-free shampoo.
- Remember how sulfates get rid of color quicker?
For that reason, if you want your color to last longer, you need to avoid them. Use a shampoo that does not contain sulfates. And, if possible, use a conditioner made for dyed hair.
- I’m someone that loves summer and when my skin starts to tan, but I still protect it with sunblock.
It’s the same with your hair. Try to avoid overexposing it to the sun, and if you need to be out in the sun for a long time, cover up with a hat.
And lastly, keep your hair well moisturized and nurtured because healthy hair always holds pigments for longer.
