The more yellow left in the hair, the less silver the toner comes out. That one line explains most silver complaints, including the good bowl that went on a 9 and sent the client home the color of wet sand. A toner deposits and cannot lift; silver is a cool tone laid over a 10 pale enough to carry it.
How much yellow is left
Judge it after the rinse, dry. In the foil, with lightener on, the hair looks white, and that white is the bleach; the rinse is always yellower. The target is the palest yellow, one you cannot quite point to, at the nape, the crown, the hairline and the ends, because they never lift the same.
Silver on a 9 reads beige. The 10.21 spends itself canceling the pale yellow and has nothing left to make the cool. On an 8 it reads muddy and dingy, and on a 7 the bowl does nearly nothing. The liquid toners sold as T18 are built for this canvas and no other, a pale yellow 10. The level 10 page has the swatch.
| What is underneath | What this bowl reads as | What to do instead |
|---|---|---|
| True, even, healthy 10 | Silver, a cool pale gray | Mix it |
| 10 at the roots, 9 through the ends | Silver at the scalp, beige below | Tone as a 9, lift the ends later |
| 9 at the roots, 10 through the lengths | Beige at the root, silver below | Shadow the root; see below |
| Even 9 | Beige, a pale sand | 9.21 (9P) now, or the 9 to 10 nudge |
| Porous, stretching ends | Silver for a week, then beige | Ends diluted 1:1 with clear, on last, two minutes |
Even from scalp to ends, or shadow it
Pearl hides a half-level band. Silver shows it. A toner cancels whatever sits under it at each spot, so on a head lifted unevenly the darker strip goes violet-brown and the paler hair beside it goes gray, and the band reads louder after the toner than before. A missed strip from a kitchen bleach comes out as a dingy stripe an inch wide, and the fix is a second lift on that strip and another toner.
The one uneven head silver forgives has the darkness at the root. A 9 at the scalp under a 10 through the lengths does not need a third bleach. Shadow it: a cool demi a level or two down, an 8 or a 9 (8V, 9P), an inch down from the scalp, blurred into the 10.21 through the lengths, so the root reads as a design and the silver reads brighter against it. It is routine work in any salon that does blondes, and some colorists build the whole silver this way, a level 8 gray-violet demi over hair lifted to 10 or 11 with clear on the tips, blended into natural salt-and-pepper so the grow-out disappears.
The bowl
The 10.21, a 10P in the letter lines, is violet with ash behind it. The violet cancels the last of the yellow and the ash pushes past neutral into cool. The touch of 10.1, the 10A, turns pearl into silver, a few grams of blue-based ash to gray the shine. More than a touch drifts green, because blue on the palest yellow makes green, and green on cool hair reads dingy. Five to one is the stopping point, and it moves by line, since ash is blue in one line and gray-green in another.
Twenty-five grams of 10.21 and 5 g of 10.1 into 60 g of 10 vol, an ounce of toner to two of developer in US terms, or the line’s toning developer at the ratio in its directions. Ten vol or lower is what makes a demi a toner. Twenty vol turns the same tube into a permanent that holds longer, and on a fresh 10 the price is too high. The developer mix calculator has the grams.
Fifteen minutes
Shampoo, condition, towel-dry until it stops dripping, and section before you mix. Roots first: the root is the least porous hair on the head and takes longest. Ends last, and the marked ends get the bowl diluted 1:1 with clear, because ends that have been through three bleaches grab the pigment while the roots are still deciding. Whole head on inside five minutes, and I start the clock when the first section goes on.
On the head it goes purple, and that is the toner oxidizing, nothing more yet. At five minutes the yellow is gone and a wiped strand is pearl. At ten there is gray in the pearl. At fifteen it is silver. Past fifteen the head goes a flat gray-violet that does not reflect light, the one over-toning at 10 a clarifying wash does not fully take back. Dry it fully before anyone decides anything; wet, it reads a level darker, and a faint violet in the first dry leaves in a shampoo or two.
Four weeks
The ash goes first. By week two the silver is pearl, by week three a cool blonde, by week four a plain 10 again, which is why silver clients are booked monthly. Purple shampoo once a week holds the pearl stage longer; it is maintenance, a little each wash, and it will not make silver out of a head that was never toned. Hard water takes silver faster than any tone.
Some colorists check the finished silver under the warmest, most orange bulb in the building on purpose, because a silver that holds there holds anywhere.
