Can you bleach dyed or colored hair?
If you have hair that has already been colored and you want to lift it or color it, it's not a question of "can you bleach dyed hair?"
The answer is you have to. There is no other way. Color does not work on color.
Nor does developer on its own, incidentally!
How do you bleach dyed hair?
The good news is done correctly, it is possible to lift and lighten previously colored hair.
Hairdressers do it all the time.
In this blog we will show you how.
Step One - Assessing The Hair
Previously dyed hair
The first step is to examine your client's hair and check its condition.
Very often hair will look like in the above picture.
This hair has been colored in the past (and bleached) and now it's looking faded and orange.
Check the health of the hair.
In this case, even by looking at it you can see that it is still in good condition.
Porosity is also OK.
Step Two - Choose the Right Bleach
Brilliant Blondexx Bleach - with Bond Protect for safe, effective lifting.
It's always a good idea to work with a quality bleach.
You will get better lifting of the hair and better hair condition afterwards.
We recommend that you use Brilliant Blondexx with Bond Protect.
It contains Plex technology, which helps build bonds in the hair.
The other reason why you should use Brilliant Blondexx is that its lifting power is quite unique - up to 7 levels, in fact.
Step Three - Choose the right developer strength
On previously bleached and colored (lightened) hair, as in the picture above, 20 Vol is generally enough.
You will get sufficient lift.
Especially with Ugly Duckling bleaches, which are quite powerful.
Using 20 Vol developer is also better for the hair.
Step Four - Mix & apply
he best mix for a full head application is 1 part bleach to 2 parts developer.
That way you get a nice wet mix which will really saturate the hair properly and process fast.
The picture below shows the mix you will get using Brilliant Blondexx. It will be white and quite creamy.

Step Five - Applying your bleach mix
Start applying your mix at the back, where the hair is thickest.
Work fast, because bleach continues to process as long as it is still wet and in contact with the hair.
In this case, we used foils.
Foils help you process faster, because you get extra heat wrapped in.
Plus we wanted to achieve a dimensional color look.
Once you have done the back, come round to the sides and the front later.
The hair here is typically finer here and will process faster.
Step Six - Rinse when you see yellow (no orange)
Once the first application is done, 15 minutes to 20 minutes will have elapsed.
Now is the time to start checking at the back - where you started to bleach.
Are there parts which are lifting less well than others?
If so, you will need to make and apply a second mix on those parts only.
Since in this case, we want to tone the hair ash blonde, we are going to target a level 9 bright yellow color as in the picture above.
If you see any orange or orange-yellow, that means it has not been bleached enough.
Rinse the hair well and towel dry it.
Step Six - Toning After Bleaching
All bleached hair needs to be toned.
If you have been successful at getting the hair to a true level 10 very pale yellow, we would suggest you use on of Ugly Duckling's demi-permanent toners Blondify.
They have been formulated to complement Brilliant Blondex bleach.
Like all Ugly Duckling toner, they are very intensely pigmented with ash and purple pigments.
And they are ammonia-free.
And they contain Bond Protect Plex Technology.
Blondify Natural Violet Blonde 010V Toner
So in this case we used Blondify Liquid toners - Natural Violet Blonde 010V.
These toners are ammonia free. Because they are liquid, they can be mixed in an applicator bottle.
The mix is 1 part color to 1 part developer - either 10 or 20 Vol developer is good.
These toners don't lift much, but they are very intensely pigmented.
They are excellent at getting rid of yellow after bleaching colored hair.
Here you can see Blondify toner processing on the hair.
