Semi-permanent vs. Permanent silver dyes, Which one should you choose for your hair?


Here, we should choose between permanent and semi-permanent dyes.

What is the difference between them?

I’ll tell you.


Permanent Dyes

Permanent dyes use 20 or 30-volume developer (depending on the tone), which breaks the hair cuticles to absorb the pigment.

They last 3 to 5 weeks and require monthly maintenance, depending on how your hair grows.


If you are looking for a silvery tone, L’Óreal age perfect has a large range of silvers that go from pearl gray to lead-gray.

Semi-permanent dyes

Semi-permanent dyes don’t contain peroxide. Generally they are gels or creams that are applied to wet hair. They are an excellent option if you don’t want to damage your hair or if you are vegan.

They last between 3 and 8 washes, and they have a wide range of colors that are very diverse and original to choose from.


If this is your option, you can choose between Maniac Panic where each tone has a different name or Arctic Fox which has colors with unconventional numbers, meaning, not those that we see or buy normally.

Once we define what dye we need to use, we go to the hair salon store or pharmacy to buy everything we need.


Now you know the difference between permanent and semi-permanent dyes.

For an example for this article, let’s suppose that you choose to dye your hair with a permanent dye.

 It could be  L’Oreal Perfect Age Pearl Gray, that is a light and very shiny silver.  


Very well, let’s see what other materials we will need in addition to the dye.


What materials to buy to dye the hair silver

Let’s suppose that you have hair dyed a deep blue.

To get to any silver or gray tone, you will need to bleach your hair. So, we will also need to buy all the materials necessary to do the bleaching.


  • 30-volume developer
  • Bleaching powder
  • Protective serum
  • Gloves
  • The silver dye you chose
  • Silver Gray toning shampoo
  • Gray Keratin bath


Now that we have all the materials, we can get to work.


First step: how to remove the blue dye from the hair

We said that we will use the example of hair dyed a deep blue, so it will be necessary to bleach to get rid of the color.

Let’s start with bleaching.


In a plastic bowl, mix the 30-volume developer with bleaching powder and protective serum. It’s an oil that protects the hair from the temperature of the process to break. When we have a homogenous mixture, we can start.


  • Apply it to the lengths and ends without touching the roots since the lengths have more pigmentation and take longer to lose it.
  • When you finish, apply to the roots.
  • You can use a thermal cap so that the process is even.
  • Let it sit between 30 and 40 minutes, checking the color every 10 minutes.
  • Once this time has passed, rinse with abundant warm water to get rid of all signs of the mixture.


And now what?

At this point, two things can happen.

If your hair got to a buttery tone, great. This is the tone we are looking for to be able to apply the silver dye.


 On the other hand, if you hair doesn’t get to that buttery tone, it will be necessary to do a second bleach, which I recommend you wait at least a week to do.  

During the first and second bleaching, you should really care for you hair and nourish it with serums or oils.


What happens is silver and gray are lighter colors, so if after bleaching, your hair isn’t sufficiently light, the new color isn’t going to take.


Step 2: apply the silver dye

Once we have bleached the hair to a light blonde, we can apply the silver color.

Before doing anything, I recommend that you read the instructions very closely for the chosen dye.


This is the point where many women make mistakes because of rushing. It’s better to take a bit longer but be sure of what you are doing.


 That’s why, I repeat, be sure to read the instructions carefully that come with the dye you bought.  


Very well, now I want to explain the general steps for a permanent dye like L’Óreal, which we mentioned before. But I insist, it’s just a generic explanation. READ THE INSTRUCTIONS ON YOUR BOX OF DYE.


  • Mix the tube of color with the developer cream until you get a homogenous mixture.
  • Apply from the roots to the ends, being careful to cover your whole hair with the dye.
  • Wait 40 to 60 minutes.
  • Rinse with your normal shampoo and apply a rinse cream.
  • Dry your hair with a hairdryer, and you will have brilliant, silvery hair and a renewed look.


How to maintain the new silver color so that it looks vibrant for longer

To maintain your silvery tone, you should follow these simple steps during your beauty routine.


  • Wash your hair with a gray toner shampoo. This will help you maintain your silver tone. Revlon 45-day gives great results. Apply it and let it sit for between 5 and 10 minutes, rinse, and ready to go.
  • Doing keratin baths with gray dye is also good for maintaining the color and restructure the hair fiber after bleaching.
  • If you chose a semi-permanent dye, remember that you should retouch the color after 4 or 5 washes.
  • If you chose a permanent dye, you should retouch the color monthly.
  • Coconut oil gives shine and softness to the hair. Apply it at night and in the morning, rinse it out.
  • Remember the tone and brand of dye that you used for the next time. Confusing the tone could make your hair look bad.



Going from blue to gray at home is completely possible if you keep in mind all the things we’ve been talking about.


 If you have any doubts, no matter how small they are, it would be best if you go to a professional colorist.  

There’s no one better to advise you about the best gray tones for your hair and help you determine the best process after evaluating your hair health.

And you, do you know what silver tone you are going to dye your hair?
