What is the difference with other types of colors

In the world of coloring there are many color options. This gives us a wide range of possibilities so that we can choose the color that is best for our needs.

Depending on the type of dye you apply will be its duration. There are dyes that penetrate our cuticle more, and others simply pigment our hair superficially.

The main types of dye are:

  • Permanent dyes.
  • Demi-permanent dyes.
  • Semi-permanent dyes.

Let’s see one by one in detail so you can know their differences:


Permanent dyes are the ones that wash out the least in the hair. These types of dyes are recommended for drastic color changes, situations where you want to pigment the hair a lot or to lighten the hair. If you want to change your hair color in a lasting way, this is your best option because the color is deposited inside your cuticle. This type of dye is the most recommended one for covering greys.


These types of dyes are a middle ground. Dye pigments slightly penetrate the cuticle, allowing the color to last for at least 20 washes on average. These types of dyes do not usually have much power to lighten the hair, so it is recommended that they be used only to deposit color. With this dye you will hide the gray hair but you will not cover it completely.


These types of dyes are like a kind of hair toners. They only have the power to deposit the color on the outside of your cuticle, which is why they are the ones that last the least. Its use is recommended for cases where you would like to tone your hair or paint your hair with a fancy color. These dyes do not have any gray coverage power.

How long does permanent dye should last?

In how long Does permanent hair dye wash out

Permanent dyes should last you at least 40 washes under normal conditions. I will now show you the most common examples of situations in which you dye your hair. So you can know how long the permanent dye will last in each one:

  • If you dye your hair a similar or slightly darker color, the dye will stay in your hair for a long time. With the washes, the color will not wash out, but what will happen is that it will lose its shine.
  • On the other hand, if you are lightening your hair to achieve a blonde or copper tone, the lightening effect will be permanent in the areas where you have applied it. What would change is the color since it will fade to brassy over time.
  • If you have light hair and want to darken it for a change, you should know that this is the case where the permanent dye will wash out faster. If you do not do a pre-pigmentation, most likely the dye after a couple of washes will have faded 50%.

Permanent dye is not removed from your cuticle, that’s the “permanent” effect. What changes is that both the color fades when you wash your hair.

How to prevent permanent dye from washing out?

How to prevent permanent hair dye wash out

The best way to prevent permanent dye from fading too quickly is to improve your hair care. If you don’t take care of the color of your hair, after a few washes you will have lost the beautiful effect of freshly dyed hair.

There are four tricks to getting the most out of your permanent hair color:

  1. Do not wash your hair for at least 5 days after dyeing it: This is essential to seal the dye into the cuticle of your hair. The more days you wait to wash your hair after dyeing, the better!
  2. Wash your hair a maximum of three times a week: Dyed hair should not be washed very often because this makes it fade faster. Ideally you should wash your hair only twice a week.
  3. Avoid very hot water: If you use very hot water when you shower, you will open the cuticles of your hair and this will cause the color to wash out faster. You don’t have to suffer either, but at least wash your hair at lukewarm temperature.
  4. Use a special shampoo and conditioner for color care: If you use a supermarket shampoo, it will easily wash out your hair even if you buy it for colored hair. If you really want your color to last longer, you need a shampoo with a specific pH and antioxidants like this one.

If you take care of your hair following these tips, you will see that you will make the permanent dye last much longer and you will avoid dyeing your hair so often.
