Steps

  1. Dry swatch at the window first. Clear yellow with no orange in it is an 8 and the formula fits. Any orange, even at the roots only, means the hair is a 7 in places and this bowl will read muddy there.
  2. Cut a small test piece from the nape, mix a teaspoon of the formula and leave it the full 30 minutes while you consult. It tells you whether the hair will move and whether the ends will grab.
  3. Mix 9.2 with 20 vol at 1:1.5 by weight; 9.21 in place of 9.2 for a pearl finish on hair that is already a pale 8.
  4. Apply to dry hair, roots first this time (on an 8 the roots are usually the warmest part and need the most time), then the mid-lengths, then the ends last, diluted 1:1 with clear if they feel rough.
  5. Look at 15: the yellow should be dulling to a flat beige. Look at 25: cool, a step lighter at the root. Rinse at 30, or 35 if the mids still read warm, never later.
  6. Rinse cool, one shampoo, condition, rough-dry, and look at it in daylight before she does.
From the chair
  • On an 8 the roots are the warm part, so unlike most toning jobs they go on first. The heat off the scalp does the last of the lift.
  • Porous ends grab violet in four minutes. Clear 1:1 in the ends portion, or you rinse a lilac tip on a cool 9 and spend the afternoon washing it out.
  • If the swatch came back muddy or greenish, the hair was a 7. Stop, and use the level 7 to 8 formula or bleach again before you tone.
The quick version

Mix permanent 9.2 (or 9.21 for pearl) with 20 vol at 1:1.5 and leave it 30 to 35 minutes on dry hair. It cancels the yellow and, on healthy hair, lifts about half a level, so an even 8 rinses as a cool 8.5 to 9. On porous hair it tones and stays an 8, and on hair that was really a 7 it goes muddy.

Tuesday, a regular, an even level 8 from a bleach three weeks ago that has gone lemon in the sun. She wants it paler and cooler and has 50 minutes. This is that appointment, hour by hour, with a permanent 9.2 on 20 vol.

10:00, the consult and the swatch

I hold a dry section against a strip of white card I keep taped inside the cart drawer, because the cart top is beige and makes everything beside it look cooler than it is. Hers is clear yellow root to tip, no orange anywhere. An 8. Under an 8 the pigment is yellow, violet cancels it, and the 9 in the code is where the 20 vol should take it. I cut a piece from the nape, mix a teaspoon and leave it in foil while we talk (she says “just a bit lighter” with her fingers an inch apart, and an inch is two levels, so we agree on half of one). The ends feel smooth when dry. One visit, then, and the swatch comes out at 10:30 to prove it.

10:15, the bowl

Forty grams of 9.2 and 60 of 20 vol, by weight, 1:1.5 on this line. In my chair I prefer 9.21 for this job; pearl reads expensive and straight violet a little clinical. Today it is 9.2 because her yellow is bright and wants canceling. A second bowl gets 10 g of the mix and 10 g of clear for the ends; the developer mix calculator scales the grams.

10:20, application, roots first

On an 8 the roots are the warmest part, so this is the one toning job where they go on first, on dry hair, the scalp heat doing the last of the lift. Mid-lengths next. Ends last, from the clear bowl; bleached ends drink violet in four minutes and go lavender while the roots are still yellow. Covered by 10:26. Under the cream it looks purple-gray, which is normal.

10:35, the check

Wipe a piece at the crown and one at the ends. Crown: the lemon has gone to a flat pale beige, and the root, held against the card, is a step lighter. Ends: cool, pale, no lilac. What I cannot see is the lift under the violet; the cream hides it, so the check is a wipe and a look, and I have been wrong by half a level both ways. At 10:45 a second wipe reads cool and pale through the mids and the roots have caught up.

10:50, the rinse

Thirty minutes. Cool water, one shampoo, condition, rough-dry. Against the card it is a cool 8.5 leaning 9, the yellow gone and a faint pearl where the light hits. Fine virgin hair can reach a clean 9 in the same 30 minutes; hair bleached twice sits at 8 and only cools.

Thirty-five is the most I would give it; past that the violet keeps depositing after the lift has stalled, and the ends go lilac and the root gray.

The 8 that was really a 7

Last winter I swatched an 8 under the cart lamp because it was raining and the window was fogged, and lamp light hides orange. It was a 7 at the crown, and 30 minutes later that crown was the color of wet cardboard, violet over yellow-orange, the developer lifting more orange under it. Thirty-five minutes and a bowl of bleach later she went home a real 8. Any orange at all and you want the level 7 to 8 formula; the toner selector will say the same.

Wet hair reads a level darker Judge the swatch and the result dry, by the window. A 9 that looks like an 8 at the basin is still a 9, and a warm bathroom bulb pushes it the other way.

Three weeks on

The violet fades first, at four to six weeks, and the hair drifts to a warm 8.5. The half level of lift stays. A purple shampoo once a week and cool rinses hold the pearl a fortnight longer. But heat tools pull the violet faster than anything, and her flat iron is why she is back at six weeks rather than eight. From then on it is a level 9 refreshed with a demi 9.2 or 9.21 on 10 vol, no more 20 vol.

What people ask at the basin

Is this a toner or a color?

A permanent color doing a toner's job with a small lift on the side. A demi 9.2 on 10 vol would cool the yellow and hold the hair at an 8; this one cools it and pushes toward a 9 on healthy hair. The push is the only reason to choose it over the demi.

How much lift will I really get?

Half a level on healthy, even hair, a full level on fine virgin hair that has only been bleached once. Nothing on porous hair. If you need a guaranteed level 9, that is bleach, a rest, and a demi 9.2 on the next visit.

Mine came out gray-beige. What happened?

Honestly, the hair was a 7 somewhere. Violet over yellow-orange makes a khaki beige, and 20 vol lifting more orange up under the violet makes it worse by the minute. A clarifying wash pulls some of it back, then bleach the warm sections to a real 8 before you tone again.

Can I leave it 45 minutes to get more lift?

No. Past 35 the violet keeps depositing after the lift has stalled, and the hair goes lilac at the ends and gray at the root. Take the lift you got and come back in two weeks if you want more.

Will it work on my highlighted ends?

Depends how porous they are. Old highlights drink violet and turn lavender before the roots have cooled, so the ends portion gets clear 1:1 and goes on last. If the ends feel like straw when dry, skip the 20 vol on them altogether and use a demi 9.2 there.
