Correcting a Colour That Has Gone Wrong

Colour correction is the service most likely to be attempted in the wrong appointment, at the wrong price, on hair that cannot take it. The technical part is mostly the theory in this series applied carefully. The part that decides the outcome happens before you mix anything.

First: is it a correction, or an adjustment?

Anything in the right-hand column booked into a standard slot will overrun, and a correction done against the clock becomes the next correction. Book it as what it is — the pricing conversation is in explaining colour prices.

Establish the history, carefully

Clients under-report, not dishonestly but because they do not know what matters. The questions worth asking specifically:

• "Has anything been on it at home?" — box colour, toning shampoos, colour-depositing conditioners.
• "Have you ever used henna?" — asked separately, because clients do not count it. Metallic salts react with peroxide, which is what the incompatibility test is for.
• "How many times has it been coloured this year?" — build-up is cumulative and invisible.
• "Has anyone tried to fix this already?" — a previous attempt changes what you are looking at entirely.

Map the head before you formulate

Corrections almost never involve one uniform problem. Work section by section and write down what each zone actually is:

• Regrowth — virgin, and usually the easiest part
• Mid-lengths — where bands live
• Ends — most porous, most built-up, most likely to grab

A formula that suits one zone will overcook another. That is the same three-zone logic that governs ordinary work, set out in refreshing mid-lengths and ends — it simply matters more here.

Then apply the theory, in order

1. Name the colour. Yellow, orange, red or green — not "brassy". The pairs are in the colour wheel article.
2. Work out why it is that colour. Under-lift, washed-out tone, overlap or over-toning are four different causes with four different answers. Neutralising brass, green and bands covers each.
3. Decide depth before tone. If the depth is wrong, no amount of tonal work will fix the result.
4. Deposit, do not lift. Ten volume, or the Tone on Tone developer. Lifting to correct tone exposes more of what you are trying to remove.

Do less than you want to

Which is also why half the toners in this range add warmth rather than remove it. Over-neutralising is common enough that the range stocks the antidote.

Some corrections are cutting plans

Worth saying plainly, because clients rarely expect it and the honest answer is often the best one:

• Heavy build-up on the ends — years of overlapping colour. Depositing more onto over-saturated hair makes it worse. This resolves through cutting over several appointments.
• Compromised condition — hair that is stretching, snapping or gummy needs time and scissors, not more chemistry.
• Something dark over something light — removing artificial pigment is a lightening process, on hair that has already had one. Sometimes the right answer is to work with it and grow it out.

A client told honestly that this will take three appointments and a couple of inches will usually accept it. One whose hair breaks in your chair will not, and neither will the people they tell.

Write down what you did

Every zone, every formula, every timing, and what each one actually did. A correction is rarely finished in one appointment, and the second appointment is only better than the first if you know precisely what the first one consisted of.

It is also the record that stops the same problem recurring — because a correction that fixes the symptom without changing the habit that caused it will be back in six months. If the cause was overlap, the fix is the root touch-up routine, not just today's toner.

And the best correction

Is the one that never happens. Nearly every case in this article traces back to a consultation that did not happen, a test that was skipped, or a promise that should not have been made — which is why reading the hair rather than the photo and knowing when not to use the product are the two most commercially valuable articles in this series.
