Corrective Color With Banding and Porous Lightened Ends
A client with natural level 5 brown hair requests an all-over level 6 neutral brown. Her history includes 1 cm of new growth, a 3 cm band of level 7 gold from a previous at-home color, midlengths at level 7, and the last 8 cm at level 8 pale yellow and porous from summer lightening. The hair feels dry. A wet stretch test shows moderate elasticity in the midlengths and poor elasticity at the ends. She wants the band gone in one appointment and has a reunion in four days. The salon has 10-, 20-, and 30-volume developers and a line of permanent and demi-permanent color. She also uses a clarifying shampoo daily.
1. Assess the color problem and explain why a single all-over formula is unlikely to produce an even level 6.

The hair has three different starting points and three different porosities, so one formula will not deposit evenly.
- New growth (level 5) needs about one level of lift to reach level 6. That requires a permanent color with developer, and the developer choice must balance lift against scalp comfort.
- The level 7 gold band is lighter than the target and more resistant in the midlengths; it needs deposit and neutralization of gold, not more lift.
- The level 8 porous ends will grab color quickly and may appear darker or cooler than the midlengths. Poor elasticity signals compromised protein structure, so a high-alkaline formula risks further damage and breakage.
A single all-over level 6 formula would over-lift or over-deposit unevenly: the roots might be close, but the band could remain warm and the ends could go muddy or too dark. The correct approach is a multi-zone formulation with a test strand, and the client must understand that “one appointment” may mean improving the band rather than erasing every trace. The reunion deadline does not justify compromising hair integrity.
2. Formulate a plan using the available developers and color types, and justify each choice.

Plan: test strand first, then zone application.
Test strand: Use the intended formula on a small section that includes band and ends. Check every 5 minutes. If the ends grab too dark or the band remains warm, adjust before committing.
Roots: A level 6 neutral permanent color with 20-volume developer is appropriate for 1 cm of level 5 new growth. It provides enough lift without the stronger alkalinity of 30 volume. Apply to the roots only, because the midlengths and ends do not need lift.
Band: Use a level 6 neutral or slightly ash permanent color with 10-volume developer, or a demi-permanent if the band is not resistant. The goal is deposit and neutralization, not additional lift. Keep it off the porous ends until the final minutes.
Ends: Use a demi-permanent level 6 neutral with 10-volume or a low-alkaline deposit formula, applied last and checked frequently. On porous hair, a shorter processing time and lower alkalinity reduce over-absorption.
Aftercare: Discontinue daily clarifying shampoo; recommend a sulfate-free, moisturizing regimen and a bond-building or protein treatment if the strand test supports it.
3. Describe the application sequence and the safeguards you would use to protect the client’s hair and the appointment outcome.

Sequence:
- Patch test and strand test before the appointment or at least 48 hours ahead when required.
- Section into four quadrants and isolate the band.
- Apply the root formula first to the new growth only, using 20 volume and staying off the previously colored hair.
- Process according to the manufacturer and check the roots visually; do not extend the time just to “make sure.”
- Rinse the roots, then apply the band formula with 10 volume, avoiding the most porous ends.
- Apply the end formula last, check every few minutes, and rinse thoroughly when the tone is even.
- Shampoo with a color-safe cleanser, apply a moisturizing treatment, and dry to assess the result in natural light.
Safeguards: strand test; overlap protection; no 30 volume on porous ends; frequent visual checks; barrier cream at the hairline; gloves; well-ventilated area; and a realistic consultation that the band may need a second, gentler visit. Document formulas and timing so the next service is predictable.
