Two Color Formulas, One Compromised Scalp
A client with natural level 3 hair, previously lightened to level 8 three months ago, wants a root touch-up to match and a refresh on the mid-lengths. She reports that her scalp has been itchy and flaky for a week and that she scratched it last night. On examination the scalp shows diffuse fine white flakes and several small excoriations at the part line, with no redness spreading beyond the scratch marks. Her hair feels slightly gummy at the ends and snaps when wet. She brought a photo of a level 6 copper result she wants instead of the level 8. You have 20-volume and 10-volume developer, a level 6 copper permanent color, a level 8 ash permanent color, and a bonding additive. The appointment slot is 90 minutes.

There are three conflicts. First, the scalp is compromised: flaky, itchy, and scratched, so any on-scalp lightener or high-alkalinity permanent color risks burning and irritation at the excoriations. Second, the target changed from a level 8 touch-up to a level 6 copper, which is a shift in both level and tone and cannot be treated as a simple root retouch. Third, the ends are gummy and snap when wet, which indicates compromised bonds; lightening them again or over-processing them will cause breakage. The 90-minute slot also cannot accommodate a color correction plus a bond-repair plan.
Today, do not apply lightener or permanent color to the scratched scalp. Offer a patch test and a strand test, then perform only a gentle cleanse and a bond-building treatment, and reschedule the color. If she insists on color, limit it to off-scalp work on the mid-lengths and ends with a low-volume developer and a bonding additive, after a strand test, and never over the excoriations. Recommend she see a physician if the flaking and itching persist.
2. Assuming the scalp clears, how would you approach the change from level 8 to level 6 copper, and why is 20-volume not automatically the right choice?

Deposit-only is the safer route. Level 8 to level 6 is a two-level drop, which a level 6 copper permanent color with 10-volume can accomplish on the previously lightened hair, because lightened hair is porous and accepts pigment readily. Using 20-volume would lift the natural root while depositing on the ends, creating an uneven result and unnecessary scalp exposure. On the natural level 3 root, a level 6 copper with 10-volume will not lift enough to match the level 6 target, so the root needs a separate formula, likely a level 6 copper with 20-volume applied only to the new growth, kept off the scalp as much as possible.
Apply the root formula first, then the mid-length and end formula with 10-volume and a bonding additive, checking a strand test first because the gummy ends may over-absorb and go darker or muddy. Refresh with a color-safe, copper-depositing conditioner. Warn her that copper fades fastest and that the porous ends will lose tone first.
