Hair toner

A hair toner shifts your existing shade a few tones warmer, cooler, or brighter without touching the hair's structure the way a permanent dye does. Our professional hair toner service suits anyone whose colour has drifted brassy between full appointments, whose blonde needs the yellow taken back out, or who wants a subtle shift without committing to a full change, and it's booked in at PIED-DE-POULE at South Kensington and Oxford Circus daily.

What Is a Hair Toner?

Toning hair works on a different principle to colouring it. A toner deposits pigment onto the surface of the strand rather than opening the cuticle to lift or replace the natural shade underneath, which is why the result reads as a correction or refresh rather than a new colour. A hair toner service at PIED-DE-POULE starts with a check of your current shade, undertone, and how much previous colour work the hair has been through, since that history decides which formula and strength actually apply. For hair that’s gone dry from repeated lightening, a bonding treatment such as K18 is sometimes recommended before the toner goes on.

Types of Toners for Every Level of Change

Two strengths cover most requests. A surface-level wash — applied as a tinted shampoo or mousse — sits on top of the hair and fades out within a handful of shampoos, useful for a quick correction you don’t want to keep reapplying. A semi-permanent formula goes further, with the pigment settling just under the cuticle surface so the shift holds for several weeks before it fades gradually, without a sharp regrowth line. Neither formula lightens hair or covers grey outright; both work by adjusting the tone that’s already there.

How a Toning Appointment Runs

A surface toner and blow dry takes around 30 to 45 minutes. A semi-permanent toning service, which needs a slightly longer processing window, runs closer to 45 to 60 minutes including the finish. Most clients rebook every 4 weeks to keep the tone consistent, and that interval is worth setting at your first visit so it’s not something you have to work out later.

Who Reaches for a Toner

Some clients book a toner as a stand-alone refresh between cuts. Others use it as maintenance for a lightening technique that’s already been done — clients keeping a balayage placement looking clean often come in for a toner top-up rather than a full reapplication. If the shift you want goes beyond a tone or two, a full head colour service is the better starting point, with toning folded in afterwards to finish the result.

How Hair Toner Salon Services Are Done at PIED-DE-POULE

Consultation

Your colourist checks your current shade, undertone, and hair condition, then confirms whether a surface wash or a semi-permanent formula fits what you're after. This is also where a repeat schedule gets set, since most toners hold their result for around 4 weeks.

Toner Application

The formula is applied evenly through the lengths or targeted at specific sections, depending on whether the whole head needs adjusting or just a part of it.

Processing Time

The pigment sits for a set number of minutes so it settles into the cuticle surface without overprocessing the strand.

Rinse and Finish

Hair is rinsed, the excess pigment washes out, and a blow dry seals the look so you leave with the corrected tone visible in daylight, not just under salon lighting.

Treatment Benefits

UNDERTONE CORRECTION
Pigment cancels unwanted warmth or brassiness, so the shade reads clean rather than yellow or orange.
SURFACE SHINE
The toner coats the cuticle rather than roughening it, so hair reflects light and looks glossier straight after.
COLOUR UNIFORMITY
Uneven patches from grown-out colour or sun exposure get pulled back into one consistent tone.
MINIMAL STRUCTURAL CHANGE
Low alkali content means the hair shaft stays largely untouched, so strength and texture carry on as before.

FAQ

What does a toner do to hair?

It shifts the existing shade a few tones warmer, cooler, or clearer by depositing pigment on the surface, without lightening or replacing the base colour underneath. It’s a correction to what’s already there, not a new colour.
What are hair toners made from, and are they harsh on hair?

Toners use a much lower concentration of alkalis than permanent dye, so the cuticle barely opens compared to a full colour service. That’s why the treatment is considered gentle enough to repeat regularly.
How long does toner last on hair?

A surface wash-in toner fades within a handful of shampoos. A semi-permanent formula typically holds for around 4 weeks before it needs refreshing.
How much is a toner for hair in London?

Pricing depends on whether it’s a surface refresh or a full semi-permanent application, and whether it’s combined with a blow dry. An exact quote is confirmed at your consultation or on the online price list.
What types of toners for hair does the salon use?

Two main strengths cover most requests – a light surface wash for a quick, temporary correction, and a semi-permanent formula for a longer-holding tone shift. Which one applies depends on how noticeable and how long-lasting you want the change to be.
How often can you use hair toner?

Most clients rebook every 4 weeks to keep tone consistent, and the surface-level version can be used more frequently since it doesn’t build up the same way. Your colourist will confirm an interval based on how your hair holds colour.
