The Six-Week Root Touch-Up With Life Color Plus, Done Properly

The regrowth appointment is the one most salons run most weeks, and the one most likely to be done on autopilot. It is also where colour quietly goes wrong over time — not in one visit, but across a year of applying the same formula to a head that keeps changing.

It is two services, not one

This is the whole article in one idea. At a six-week appointment you are looking at two different problems on one head:

• The regrowth — virgin hair, no artificial pigment, fresh white, and it needs full coverage.
• The lengths and ends — already coloured, already porous, and they need tone, not more depth.

Treating them as one job is the single most common cause of the two problems clients bring back: ends that get progressively darker and flatter over a year, and a visible band where the regrowth meets the old colour.

The regrowth, properly

Whatever the client's grey percentage is today, that is the formula — not what it was two years ago.

• Up to 50% white: the desired shade alone, standard 1:1.5, with five minutes added to the normal development time.
• 50–100% white: half the desired shade plus half the natural at the same depth, mixed 1:1, with 20 volume, developed for the full 45 minutes.

Full protocol in the grey coverage guide. Twenty volume is the coverage strength — reaching for 30 to "make it grab" lifts the client's remaining natural pigment rather than depositing more, and on a mostly-white head there is very little left to lift.

Apply where it is hardest first

Temples and front hairline usually carry the most white and the most resistant texture, and they are the areas the client looks at. Starting there gives them the longest development. Sectioning in a brickwork pattern rather than straight partings stops any regrowth being shadowed by the section above it.

The lengths: refresh, do not repeat

Putting your full-strength root formula through the ends every six weeks is what turns a level 7 client into a level 5 client over eighteen months, one appointment at a time. Nobody notices it happening. Everybody notices the result.

What the ends actually need is tone put back, with no lift:

• 10 volume (3%) — the tone-on-tone, deposit-only option, or the dedicated Life Color Tone on Tone cream developer at £3.56.
• The same shade or slightly lighter — never darker. Porous ends grab, so a shade that looks right in the bowl lands deeper on the hair.
• In the last ten minutes, emulsified through with a little water rather than applied thickly.

Costed against a £3.49 tube, that refresh is pennies. Its absence is the reason a client eventually asks to "go back to how it used to be" — which is a much longer appointment. There is more on this in refreshing mid-lengths and ends.

Check three things every time

None of these takes more than a few seconds, and they are the difference between a formula that stays right and one that slowly stops fitting the client it was written for.

The band, and how to avoid making one

A demarcation line appears where the new application overlaps hair that was already coloured — a stripe of double-processed colour sitting a shade darker than everything around it.

Two habits prevent it:

• Apply to the regrowth only, right up to the line and not past it. Overlapping "to be safe" is what creates the band.
• Do the lengths as a separate, lower-strength step, which blurs the join rather than stacking on top of it.

Book the next one before they leave

The interval is a technical decision as much as a commercial one. Leave it too long and the regrowth is wide enough that the root lifts differently from the rest, which makes the join harder to hide. Six weeks keeps the band narrow and the formula predictable.

It is also the easiest rebooking conversation there is, because you can point at the reason: "your regrowth will start showing at about five weeks, so let us get you in before it does."
