Balayage formula

Balayage formula: level 5 to 8

The test piece at 10 and 20 minutes, the foil and the 30 vol it calls for, what every check should show, and the two-bowl toner that turns a warm 8 into light blonde.

Published 2026-10-23. Written by the Easy Hair Edit team and checked against the rules the rest of the site follows.

Before and after: light brown hair at level 5, then hand-painted balayage reaching level 8 on the ends
Left: light brown hair at level 5, before. Right: a warm level 8 through the painted pieces, yellow with some orange near the top, toned to a soft light blonde over the natural 5, after powder lightener with a bond builder in the bowl or built in on 30 vol, 30 to 45 minutes in the foils.

The formula
In the chair: 90 to 150 min, toner included Hard Lasts 3 to 8 months between lightenings; the toner 4 to 8 weeks
Product
Powder lightener with a bond builder in the bowl or built in, in foils; then a demi 8.2 (8V) with a little 8.1 (8A) through the lengths and a 6N or 7N tapped at the root
Developer
30 vol (9%) off the scalp in the foils; 10 vol (3%) or the line's toning developer under the toner
Ratio
1:1 to 1:1.5 for the lightener, thick enough to hold its edge; the toner at the ratio on its tube
Amount
30 g of powder, about an ounce, to 30 to 45 g of 30 vol per bowl; mix what goes on in the next 15 minutes, then mix again
Processing
30 to 45 minutes in the foils; open the first foil at 10, then every 5 to 10; rinse in painting order
Result
A warm level 8 through the painted pieces, yellow with some orange near the top, toned to a soft light blonde over the natural 5

Steps

  1. Ask the history before you read the level. Box color, henna, an old balayage on the ends: any of it changes the day, and the lightener leaflet says not to use it on hair treated with henna or metallic dye. Then paint one piece at the nape, foil it, and open it at 10 and at 20. Orange-red at 10 and orange going yellow-orange at 20 is a virgin 5 lifting on schedule.
  2. Patch test 48 hours ahead, a dab behind the ear or in the crease of the elbow, every time the product changes.
  3. Weigh 30 g of powder into 30 to 45 g of 30 vol with the bond builder at its own dose, non-metal bowl, whisked until there are no lumps. A second small bowl of 10 vol for any ends that were lightened before.
  4. Four quadrants off her natural part, nape first. Diagonal-back subsections, each one teased from mid-shaft up, then painted from the mids down: opaque through the ends, feathered up into the tease with less product and less pressure, never pressed through. Foil folded over it.
  5. Hairline and baby hairs last, the finest sections and the least product. Some colorists step the front bowl up to 35 so it catches the back; most stay on 30 throughout.
  6. One timer once the last foil is in. Open the first foil at 10 and every 5 to 10 after; rinse foils in painting order between 30 and 45, when the wiped piece reads yellow dry.
  7. Shampoo, condition, towel-dry. Tap a 6N or 7N at the root of the lifted pieces, then an 8V with a little 8A through the lengths, both on 10 vol, 5 to 10 minutes, watched. Bond step 10 minutes, then dry it fully before anyone judges it.
From the chair
  • Wet hair reads a level darker and a warm bulb reads it lighter and more golden. Wipe the piece, dry it between two fingers, and read the level before you decide anything.
  • Fresh 30 vol never goes back over hair that was lightened before. Leave those pieces out of the foil or give them the 10 vol bowl.
  • Pick the toner after the rinse. The same 8V reads different on a piece that lifted gold and one that lifted ashy, and a toner bought before the lift is a guess.
Before the first foil

Powder lightener with a bond builder, mixed thick at 1:1 to 1:1.5 with 30 vol (9%), painted from the mids down on teased diagonal-back sections and folded into foils for 30 to 45 minutes takes a level 5, light brown, to a warm level 8. Rinse in painting order, then two demi toners on 10 vol: a 6N or 7N tapped at the root and an 8V with a little 8A through the lengths, 5 to 10 minutes. Open air stops a level or two short.

Ten minutes in, the nape piece wiped back to orange-red, the pigment under a level 5, light brown. At 20 it was plain orange, the last inch going yellow-orange. Two stages in twenty minutes inside a foil is a virgin 5 lifting on schedule, and it settled the day: foils, 30 vol (9%), 30 to 45 minutes, a toner picked after the rinse.

Still orange-red at 20 would have meant old color the history missed, or a coarse head whose day ends at a warm 7, a 7.12, and a second visit for the 8.

How many levels can balayage lift a light brown?

Three, in foils: a virgin 5 on 30 vol comes out a warm 7 to 8, sometimes 8 to 9. Open air on the same powder gives a couple of levels, maybe a few, so an 8 through the ends in one visit is a foil job. Thirty vol is the everyday balayage developer because the paste never touches the scalp.

Is foilyage the same thing as balayage?

It is the same painting with a foil folded over each piece. The foil holds the warmth of the head and keeps the paste moist, so the piece lifts faster and lighter than in open air, which is why a light brown that wants a real level 8 in one visit goes into foils. Painted pieces often go into foils and are still called balayage. The root is teased first so the top has no hard line.

Thick mix, teased root, foil on top

A bowl of 30 g powder, roughly an ounce, with 30 to 45 g of 30 vol and a bond builder at its own dose, whisked thick enough to hold its edge, since a runny mix bleeds. Sections run diagonal-back so each painted piece falls over an unpainted one, nape first. Every section is teased from mid-shaft up before any paste goes on. Paint starts at the mids: opaque icing through the ends, feathered up into the tease with less product and less pressure, never pressed through. Hairline and baby hairs go last, finest sections, least product, since they lift fastest and snap first. Then the foil, folded over.

From the first look to the rinse

One timer, set when the last foil is in, and the foil you open is the first one you painted.

MinuteThe wiped pieceWhat to do
10Orange-red, the pigment beneath a 5Fold it back
20Orange, ends turning yellow-orangeSome step the front bowl to 35 if the nape leads
30Yellow-orange mids, yellow endsEarliest rinse for the first foils. Wipe, dry, read
40Yellow, orange still near the top of each pieceRinse in painting order
45Whatever it readsThe ceiling. Longer only damages

Under the paste a piece reads whiter than it rinses, and wet it reads a level darker, so read a wiped piece dried between two fingers, then check how many foil minutes this texture wants.

A strand that stretches comes out now Pull a wet piece at every check. If it stretches and stays stretched, or feels gummy, rinse that foil that minute, whatever the timer says.

Why does balayage on light brown hair go orange?

Because orange-red sits under a level 5, and any piece rinsed before it reaches yellow is rinsed on orange. Open air stops a level or two short of an 8, and a foil rinsed early comes out more orange than it looked under the paste. A toner cancels warmth at the level the hair reached and does nothing for orange at a 6, so orange at the rinse means a 7.12 today or the foils again another day.

Toned where it landed, and the months after

Shampoo, condition, towel-dry, then two formulas at the bowl: a 6N or a 7N tapped where each lifted piece begins, an inch down, and an 8.2 (8V) with a little 8.1 (8A) through the lengths, violet-blue for the yellow and trace of orange an 8 shows. Ten vol or the line’s toning developer, 5 to 10 minutes, ends last because they grab. The demi that finishes a lifted 8 is that bowl. Most tap a root shadow so the grow-out has no line, and a few leave it out because the next lightener has to lift through that deposit and bands there. Better to send a first visit home a clean warm 8 than chase a 9, which is usually a second round and the 5 to 9 version. The next lightener is 3 to 8 months out, on the regrowth and the dark pieces only.

Four things people ask before the foils

How long does balayage take to process?

In foils on 30 vol, 30 to 45 minutes, and in open air 40 to 50. The first foil painted is the one you open, at about 10 minutes and every 5 to 10 after, because the timer is only a reminder to look. Painting a full head takes another 30 to 45 minutes, so with the toner the appointment runs 90 to 150 minutes.

Can I skip the toner if I like it warm?

Some colorists let a sun-kissed balayage go home untoned when the lift is even and the client likes gold. Most tone every head, because a level 8 rinses yellow with orange near the top of each piece, and the demi is what turns that into a light blonde. Hair that rinses orange rather than yellow stalled at a 7 and wants a 7.12 toner, or more time in foils another day.

Some of my ends are still blonde from an old balayage. What happens to them?

They stay out of the fresh 30 vol. Lightener laid over hair that was lightened before is how balayage ends snap, so those pieces are left out of the foil or painted with the 10 vol bowl, which lifts almost nothing and keeps them from sitting bare beside a working foil. Their toner is the same two bowls, ends last, with clear mixed in if they grab.

Will balayage damage my hair?

It is lightener, so some, and this page keeps it small: a bond builder in every bowl, 30 vol that never touches the scalp, 45 minutes as the ceiling, and a pull on a wet piece at every check, because a strand that stretches comes out of the foil that minute. Afterward a bond step for 10 minutes, and the next lightener is 3 to 8 months away, on the regrowth only.
