The bleach is rinsed. You have towel-dried it and walked it to the window, and there it is: yellow. Warmer than the swatch, leaning orange at the roots and nearly white at the ends. And then, while she is still looking at you in the mirror, the question: now what?
What level is it, really?
Hair looks a level lighter wet and a level lighter again under a warm bulb, which is why every head goes to the window by the back door before I mix, even in January, when the light out there is gray and the client is shivering in a towel. Dry a section and hold it against the level chart in daylight. If you are between two numbers, choose the darker one. A toner picked for a 9 and applied to an 8 goes quietly muddy, and the client spends the week wondering why her "silver" looks like wet cement (clients photograph results in bathrooms, under the worst bulb in the house).
The slider runs from 5 to 10 because below 5 there is too much red for deposit alone to cancel.
What color is fighting you?
Every level has a pigment underneath that the bleach uncovers, and the tone you see is that pigment. Level 6 is orange, 7 yellow-orange, 8 yellow, 9 pale yellow, and 10 the palest yellow, close to cream.
If what you see does not match the level you set, believe your eyes. Orange on a supposed 8 means the lift is lower or uneven, and the tool will say so. What it cannot see is a head that is two levels at once, a 9 on the ends and a 7 at the scalp; there I strand test both and go by feel.
Which toner cancels it?
Opposites cancel: blue sits across from orange, violet across from yellow, and the in-between tones want an in-between mix. On the tube, .1 or A is blue-based ash, .2 or V is violet, and .12 or .21 is the blend.
| Level | Underlying pigment | Neutralizer | Example toner |
|---|---|---|---|
| 5 | Red-orange | Blue-green | 5.1 / 5A (reads as a cool brown) |
| 6 | Orange | Blue | 6.1 / 6A (cool dark blonde) |
| 7 | Yellow-orange | Blue-violet | 7.12, or 7.1 with a touch of 7.2 |
| 8 | Yellow | Violet-blue | 8.1 with 8.2 for ash, 8.13 for beige, 8.3 for honey |
| 9 | Pale yellow | Violet | 9.2 / 9V, 9.21 for pearl, 9.13 for beige |
| 10 | Palest yellow | Violet or pearl | 10.21 / 10V, or clear with a drop of violet |
Straight blue on pale yellow drifts green, and straight violet on orange does almost nothing.
How light can the result be?
A toner deposits and cannot lift. The result can never be lighter than the hair you are toning, and some results need a lighter base than others. Silver, pearl and platinum need a 9 or a 10 underneath. Beige wants 8 or 9. Cool ash starts working at 7 and looks its best at 8 or 9. Neutral, honey and rose gold are forgiving, though at 5 and 6 they read as brown.
I had a client last spring who wanted silver on a solid 7, yellow-orange root to tip, with the photo as her lock screen, lighting up on the cart every few minutes. What I actually said was that the hair could take a cool ash today and come out a dark ash blonde, and that silver was two visits away. She was disappointed for about a minute. She saw the yellow-orange for herself against the chart, we did the 7.12, and three weeks later we lifted to a 9, toned with a 9.21, and got a soft pearl close enough that she stopped showing me the photo. If the level cannot carry the result you want, lift again once the hair has rested a day or two, or choose a result the level can support. Toning anyway is how a 7 ends up khaki. Pick the toner at the hair's own level or one lighter. Two levels lighter is mostly developer and will not hold, and darker drags the hair down more than you expect.
Developer and timing
Ten volume, almost every time. A demi-permanent cream goes on 10 vol or the brand's own toning developer, mixed by weight at the tube's ratio. A liquid or gel toner goes 1:2 with 10 vol. Twenty volume is only for a permanent color at level 9 or 10 when you want a nudge of lift with the tone. But I have never liked it even there; in my chair it is 10 vol and a second visit. The developer mix calculator turns the ratio into grams.
Then watch the clock. Liquid toners work in 5 to 15 minutes and want a look every 2 to 3. Demi creams take 10 to 20. On high-porosity hair, start checking at 5 minutes, put the toner on the ends last, and dilute the ends portion 1:1 with clear. I say dilute because I once forgot, on a woman bleached twice that month, and by the time I had finished the roots the last three inches were lilac. Properly lilac. It cost me two clarifying washes and forty minutes promised to the next client. Porous ends drink color and go ashy before the roots have moved. The processing time calculator covers unusually fine or coarse hair.
When toner is the wrong tool
A toner cancels unwanted tone, and that is all it does. It is the wrong tool when:
- The hair is not light enough for the result. That calls for more lift.
- The lift is patchy. Toner cancels the yellow on light bands and ignores the orange ones; even the lift first.
- You want the hair darker. That is a demi or permanent color at the target level.
- The warmth is old dye. Toner cannot cancel artificial pigment; that is a remover's job.
Permanent color is the borderline case: on a 9 or 10 with 10 vol it tones with a whisper of lift; on an 8 or below it lifts warmth while trying to cover it, and you end up warmer, and more permanently so, than you wanted.
A toner is a sheer, deposit-only color that sits near the surface and fades over four to six weeks. If it came out too cool, a clarifying wash pulls some of it back. If it came out warm, another round in a week, a little deeper, sets it right.
