What is a colour correction? A Jo Hansford colourist's guide
From unwanted darkness and brassy tones to banding and complete colour changes, colour correction is one of the most considered services a colourist performs.
BOOK A COLOUR CONSULTATION
Colour correction is one of the most technically demanding areas of professional hair colour, and one in which the Jo Hansford colour team has particular expertise. Whether correcting unwanted darkness, neutralising brassy or ashy tones, balancing uneven colour or rebuilding a shade after years of home or salon colour, every correction requires experience, precision and a thorough understanding of how the hair will respond.
At Jo Hansford, colour correction is never approached as a single technique or a quick fix. Our colourists assess the hair’s history, condition and existing colour before deciding how best to proceed. From there, they create a tailored plan, often combining several techniques to achieve the desired result while protecting the condition of the hair.
This level of expertise is particularly important because no two corrections behave in quite the same way. Hair holds a history of everything that has been applied to it, and that history is not always visible at first. Two clients may arrive with seemingly similar colour, yet their hair can respond very differently once the correction begins. Knowing how to read those changes, adapt the plan and understand when to proceed or when to stop is where the experience of a specialist colourist really matters.
THE STARTING POINT
What colour correction actually involves
Most corrections fall into four areas, and it is quite common for more than one to be involved.
UNWANTED DEPTH
Colour that has gone too dark
Often the result of home colour or a shade chosen without the natural base in mind. Artificial pigment needs to be lifted carefully rather than simply covered with more colour.
TONE
Brassy, ashy or flat colour
Blonde can become brassy, brunette can lose its richness and grey hair can pick up unwanted warmth. Tonal correction can make a significant difference, although it may form only one part of the overall plan.
EVENNESS
Banding and uneven colour
Different depths through the lengths, visible regrowth lines or over-processed areas can all make colour look uneven. Each area may need to be treated differently to bring the result back into balance.
TRANSFORMATION
A complete change of colour
Moving from brunette to blonde, returning from blonde to brunette or changing a long-held colour completely draws on the same technical thinking as corrective work.
WHY TIME MATTERS
Why it often takes more than one appointment
Hair has a limit to how much can sensibly be asked of it in one day.
Lifting artificial pigment is a controlled process. Taking it too far in one session does not create a better result. It can leave the hair compromised and less able to hold the tone we are trying to achieve.
Where a correction requires several shades of movement, we may stage the work over more than one appointment. This gives the hair time between visits and allows the colourist to reassess how it has responded before taking the next step.
Previous colour can also reveal itself as the hair lightens. Old pigment does not always sit evenly, and underlying warmth may appear along the way. That is one reason a correction can evolve as the work progresses.
For some clients, two visits are enough. For others, the plan may run over several months. The important thing is that the hair looks considered and wearable at every stage, and that the likely timescale is discussed before the work begins.
THE CONSULTATION
What your colourist will assess
Every correction starts with a proper consultation. This is where we understand the hair, talk through the result you want and work out the safest and most realistic route to it.
Your colour history
Including home colour, henna and when the hair was last coloured.
Your natural base
And how much of your natural colour is currently visible.
Condition and porosity
Looking separately at the roots, mid-lengths and ends.
Previous build-up
Where colour has accumulated, banded or lifted unevenly.
Your colouring
Including skin tone and how the finished shade will sit against it.
Your everyday routine
How you wear your hair and the level of maintenance that suits you.
The result you want
And the realistic route from your starting point to that result.
A strand or pigment test may be recommended. It gives the colourist useful information about how the hair is likely to respond before the full service begins.
YOUR APPOINTMENT
What to expect
Expect time, a clear plan and an honest conversation about what your hair can achieve.
A colour correction appointment is usually longer than a standard colour service. If the shade you want cannot be reached in one visit without putting the condition of the hair at risk, we will tell you and explain the best route forward.
Condition leads the conversation. Beautiful colour relies on hair that can support it, hold its tone and continue to look good after you leave the salon.
Maintenance is part of the plan, not an afterthought. Corrected and colour-treated hair benefits from the right cleansing, conditioning and protection at home, with products chosen for your particular hair and colour.
Above all, expect to be listened to. No two colour histories are the same, and the plan should be built around your hair rather than a technique applied to everyone.
COLOUR CORRECTION
Questions we are often asked
What is colour correction?
Colour correction is the professional process of putting right colour that has not turned out as intended. This may involve removing unwanted depth, correcting tone, evening out banding or rebuilding colour after previous applications.
How long does colour correction take?
It depends on what is already in the hair and how far the colour needs to move. Some corrections can be completed in one longer appointment, while others are safer and more successful when planned over two or more visits.
Can colour correction be done at home?
We would always recommend having colour correction carried out professionally. Applying further colour at home can make the existing colour more complex to correct and may affect the condition of the hair. At Jo Hansford, a correction begins with a thorough assessment of your colour history, the condition of your hair and how it is likely to respond, so your colourist can plan the safest and most effective route forward.
Will colour correction damage my hair?
Corrective work can involve lightening, so condition is assessed before the service and throughout the process. Where necessary, the work is staged rather than pushing the hair too far in one appointment.
