Toning after bleaching: why blonde hair needs it
Why is toning needed after lightening, and how does it work?
Toning after bleaching gives blonde hair its final shade. Lightener only removes part of the pigment, and what it leaves behind is a yellow or orange undertone, while the hair itself becomes porous. Toner neutralises the unwanted warmth, adds the shade you are after and evens out the colour along the whole length. Without toning, even well-lightened hair usually looks yellowish and unfinished.
What is left on the hair after lightening
Lightener works in an alkaline environment: it opens the cuticle and oxidises melanin. Dark pigment breaks down faster, while warm pigment hangs on longer. That is why hair lightens in stages, through red, orange and yellow. Even very light hair has a slight yellow cast after lightening, because that is the natural residue of pigment. It is also why the result is not judged before toning: straight after the powder is rinsed off, the hair can still look yellow, and that is a normal in-between stage.
The second thing that changes is the structure. After lightening the cuticle no longer lies as flat, and the hair becomes porous: it absorbs water and pigment faster and loses them just as fast. As a result, lightened hair can look dull and tangle easily.
Toning handles the colour side of this. The reconstruction I do at every visit alongside toning deals with the structure.
How toner neutralises yellow
This is where the colour wheel comes in. Opposite colours cancel each other out: violet neutralises yellow, blue neutralises orange and green neutralises red. A colourist looks at the undertone left after lightening and chooses a toner with the right amount of the opposite pigment.
The aim is not always to remove all the warmth. For a beige or honey blonde part of the warm undertone is kept, because it is the foundation of the shade. For a cool pearl blonde it is neutralised more strongly.
Toner cannot remove an undertone the hair has not yet lifted past. If the strands are orange after lightening, a violet toner will not turn them pearl: the opposite pigment can only soften the warmth at the level already reached. So the level of lift and the toning are planned together, before the powder goes on. If yellow tones are bothering you at home, I go into the causes in the article on yellow tones after bleaching.
Toning after Airtouch and other techniques
After Airtouch, relief or contouring, toning does one more important job: it ties the light strands into your base. The lightened hair is brought to the right shade, and the transition from root to ends looks soft, without yellow patches. At a correction the lengths are often toned without being lightened again, and that is enough to make the blonde look fresh.
That is why toning is part of every service I offer: Airtouch, relief and contouring. On its own, without lightening, there is a separate toning and reconstruction service.
Toner does not last forever. It gradually washes out, fastest from the porous ends, and the blonde turns warm again. This does not mean the lightening has "faded": the toner pigment has simply left the hair, and the undertone beneath it is still there. How often to refresh it and what speeds up the fading is covered in the article on how often to tone blonde hair.
Why toner does not lighten and how it differs from dye
Toning uses semi-permanent colours with a low-strength developer, or acidic toners. Their job is to deposit pigment rather than lift the level. In other words, toner does not make hair lighter. It only changes the shade of what is already there.
Acidic toning has a lower pH than alkaline toning, so it opens the cuticle less and is gentler on hair that is already lightened. Hair often looks glossier afterwards. Alkaline toners last longer but have a stronger effect on the structure. Which one to choose depends on the condition of the hair and how long you want it to last.
Porosity and why the ends can go darker
The ends are usually the oldest and most porous part of the hair, especially if they have been lightened more than once. Porous hair soaks up pigment more greedily, so the same toner can come out darker or cooler on the ends than near the root. That is where complaints like "my ends went darker after toning" or "they turned greyish" come from.
To avoid this, porosity is taken into account before anything is applied. Porous areas call for a softer formula or a shorter time, and before toning the structure is evened out with treatment. The chelation at the start of the service helps as well, because hair free of metals and mineral build-up takes pigment more evenly. If the hair is badly damaged, toner will also wash out of it faster, and honestly the condition has to be addressed first and the shade second.
Toning with reconstruction with me
With me, toning is part of every lightening service, together with chelation and reconstruction. If you already have blonde hair and want to refresh the shade without lightening, there is a separate toning and reconstruction service from 700 UAH. It includes chelation too.
