If you enjoy hair coloring as much as I do, you probably know the different ways of altering hair color.
Of course, semi-permanent hair dye is one!
This type of dye is ideal for people who wish to change their hair without devoting much effort and time to the process. It requires less commitment and is low-maintenance.
The question is, how long does semi-permanent hair dye last on the hair?
Well, this article is here to answer that!
So read along as we learn more about semi-permanent hair dyes — how long they last, as well as some tips to make them last longer.
So without further ado, let’s begin!
How many washes does semi-permanent hair color last?
Semi-permanent hair dye can last around 8 to 10 washes.
Make sure you use shampoo and conditioner suited for colored hair to maximize the color’s longevity.
Washing your hair less frequently also makes the color last longer.
Is semi-permanent hair dye damaging?
Nope! These hair dyes are safe to use as they do not contain ammonia and peroxide.
And unlike permanent hair dyes, they do not open the hair shaft and lift the hair’s natural color pigment. They also have little to zero peroxide percentage.
Semi-permanent dyes do not cause chemical processing. It does not penetrate the hair and merely deposits color onto your tresses.
However, improper use of hair dye may cause damage. If you’re not careful, you may over-process your tresses, making them brittle and more prone to breakage.
So be sure to read and follow the instructions stated on the packaging.
Also, you have to be careful if you have psoriasis or seborrheic dermatitis. Although it doesn’t damage your hair, it may cause scalp inflammation. So it’s best to consult with your dermatologist first.
How long does semi-permanent hair dye last vs permanent?
Again, semi-permanent hair dye only colors the surface layer of the hair. It does not open the hair shaft, and it lacks ammonia and hydrogen peroxide, which are the main ingredients in permanent dyes.
Semi-permanent dye fades in approximately 3 weeks. Chemical processing or oxidation cannot take place without ammonia and hydrogen peroxide. Hence, hair color cannot penetrate the cuticle and modify its structure.
On the contrary, permanent dyes undergo oxidation. Ammonia and hydrogen peroxide opens up the cuticle and interacts with keratin and melanin, altering the structure and depositing pigment.
So permanent hair dye can last for 6-8 weeks. It may require a root touch-up every 4 weeks as dark roots become visible once the hair grows out.

How long does semi-permanent hair dye last on bleached hair?

But how long does it last on bleached hair?

How do you make semi-permanent hair dye last longer?
We already know that this type of hair dye fades away over time. But is there any way to make them last longer?
Here are some techniques you can follow for a longer-lasting color:
Use cold water
When it comes to hair coloring, warm water is your #1 enemy!
Hence, only wash with cold water. Cold water keeps the cuticle closed, thereby maintaining color vibrancy and vividness. It also delays color fading.
As mentioned earlier, semi-permanent hair dye fades every time you wash your hair.
Washing your tresses every day strips away sebum that protects your hair color. Hence, minimize washing every week for longer-lasting color.
Also, when washing, use gentle shampoos that maintain color vibrancy.
Use sulfate-free conditioner
Aside from color-safe shampoos, use sulfate-free conditioners too!
Sulfate-free conditioner strengthens colored tresses, making them healthy and moisturized.
Avoid sun exposure
Too much sun exposure removes color from your hair, causing it to fade.
So avoid direct sunlight as much as possible!
Avoid swimming pools
We all know pools have chlorine. And chlorine doesn’t mix very well with hair dyes because it strips the color from your tresses.
So say goodbye to swimming pools for now!
Avoid heat-styling tools
Heat-styling tools also do not go well with semi-permanent hair dyes. So avoid using them if possible.
But if you must, apply a heat protectant beforehand and put the heat-styling tool at a low temperature.

Semi-permanent hair dye is not washing out!
From the name itself, they’re not permanent. Typically, they wash out after 8-10 shampoo sessions.
Although it washes off on its own, it can be a little tricky at times. Hmm… What?
In some instances, the dye does not wash out even after 10 washes.
Don’t worry, though! You can combat this hair dilemma by simply following the methods listed below. Note that these methods may require 2-3 washes before completely stripping the color.
A deep-cleaning shampoo is the least damaging alternative for removing semi-permanent hair dye. The best option is a deep cleaning shampoo formulated to combat heavy dandruff and dry scalp.
Its cleaning ingredients help remove color while keeping your hair and scalp rehydrated.
Anti-dandruff shampoo + baking soda
The next option is using an anti-dandruff shampoo and baking soda.
Baking soda? Isn’t that what they use in baking?
Yes! Baking soda is also a gentle and powerful stripping agent that removes oils, hair products, and even semi-permanent hair dye from your tresses. It leaves the hair extremely clean and pristine.
In doing this method, simply mix a tablespoon of baking soda with a few ounces of water. Next, put the mixture on a spray bottle and sprinkle it on the hair. Make sure you fully coat all the hair. Leave it on for 5 minutes and rinse after.
Finally, apply an anti-dandruff shampoo and gently massage your hair. Rinse afterward. Repeat this method until the color is thoroughly washed out.
If you’re looking for a cheaper alternative, consider using dish soap.
Similar to baking soda, dish soap is also a strong stripping agent that removes oils and hair dyes from the hair.
Simply apply the dish soap like any other shampoo. Make sure you follow up with a nourishing treatment as it can dry out the hair and scalp.
A color-removing product is, by far, the fastest technique for eliminating semi-permanent hair dye. The color remover is a potent mixture that breaks down the links between color molecules.
And once these molecules are broken down, you can easily wash out the color with water.
Also, remember to follow all the instructions stated on the packaging. Improper use of the product may damage your tresses and worsen the dilemma.
Does semi-permanent dye wash out of bleached hair?
Yes, but it would not wash out after 8-10 washes. Simply put, these dyes are harder to remove on bleached hair.
This is because bleaching causes high porosity and damage. As a result, your tresses fully absorb your new hair color.
If this happens, what should you do?
Fortunately, some remedies can help remove semi-permanent dye from bleached hair.
Let’s have a look at these methods!
Vitamin C and Anti-Dandruff Shampoo
This is a good choice if you prefer a natural remedy.
Simply crush the Vitamin C in a bowl until it turns into powder form. Next, add a generous amount of anti-dandruff shampoo and mix the two ingredients.
Once done, gently apply to your damp hair. Massage your hair for a few minutes and put on a shower cap afterward. Wait for 45 minutes and then rinse. And lastly, don’t forget to condition your tresses!
Homemade vinegar rinse
We all know that vinegar is acidic. Its acidity helps remove semi-permanent dye from bleached hair.
To begin, use plain vinegar and apply it to your tresses. Make sure every part is coated.
Next, let it sit for about 2-3 minutes, and then rinse with warm water.
Repeat as needed but never do this method more than 3 times a week as the vinegar’s acidity level may damage the hair.
And similar to the “semi-permanent hair dye not washing out” dilemma, you can also use dish soap, color-removing products, anti-dandruff shampoo, and baking soda to remove the dye from bleached hair.
Also, don’t forget to treat your hair with caution. Keep in mind that bleached hair is more susceptible to breakage. So be extra careful when doing any of these methods.
So there you have it!
Semi-permanent hair dyes are safe to use. They are gentle on the hair since they lack ammonia and hydrogen peroxide. So no need to worry about dryness and damage!
The colors also last up to 10 washes, making it the best choice for people who cannot commit to permanent hair color.
So, are you ready to try on semi-permanent hair dyes? The choice is yours!
