Three Levels Darker Before a Wedding
A client with level 7 hair, about 50% gray at the roots and previously lightened mid-lengths (level 8), wants a level 4 warm brown for a wedding tomorrow. She scratched her scalp last night and has a 2 cm abrasion at the crown. The dispensary has 10, 20, and 30 volume developers, a permanent color line, and a deposit-only demi-permanent line. A strand test from her nape, treated with 20 volume for 30 minutes, feels mushy and stretches before breaking. She is adamant about doing it today.
1. Which product and developer would you choose, and how would you apply it?

Goal: go darker, not lighter. Going from level 7 to level 4 is three levels of deposit, so the formula should deposit pigment with minimal lift.
Plan:
- Roots: permanent color at level 4 with 10 volume for gray coverage. Permanent color is needed because demi-permanent will not cover 50% gray reliably.
- Mid-lengths and ends: a deposit-only demi-permanent at level 4 with the lowest developer, because this hair is already lightened and porous and will grab color fast.
- Pre-pigment/filler: because the mid-lengths are level 8 and the target is level 4, a warm filler step helps avoid a muddy, flat, or green result.
- Apply roots first, then pull the mid-length/end formula through only for the last 10 to 15 minutes, checking visually.
Reasoning: using 20 or 30 volume to go darker adds unnecessary lift and warmth while increasing damage. Three levels of darkening on porous hair also risks over-absorption, so a filler and a short mid-length processing time protect the result.
2. How do the scalp abrasion and the one-day timeline change your decision-making?
Read the worked answer
The abrasion: broken skin is a contraindication for color on that area. Color on an open wound causes stinging, burning, and possible infection, and it is not a risk worth taking for a cosmetic service.
Options:
- Reschedule, or
- Work around the abrasion with a barrier and keep all product off the broken skin, with client consent documented.
The timeline: a wedding tomorrow means there is no room for a corrective service if something goes wrong.
Reasoning: consent does not remove the risk of applying chemicals to broken skin. Because the strand test already shows compromised hair, the safest professional judgment is to reduce aggressiveness, avoid overlap, and be honest that a same-day dramatic change carries a higher failure risk. If the client insists on a full root-to-end application, that is a reason to decline and rebook rather than to proceed faster.
3. What could go wrong if you simply applied level 4 with 20 volume from root to end?
Read the worked answer
Predicted failures:
- Over-deposit and darkness at the ends: porous, lightened hair absorbs pigment quickly, so the ends can go far darker than level 4 while the roots look lighter.
- Muddy or green cast: darker pigment over lightened hair without filler can look flat or ashy.
- Breakage: 20 volume plus overlapping on hair that already stretches before breaking increases damage.
- Scalp injury: product on the abrasion will burn.
- Uneven gray coverage: 20 volume at the root lifts and can leave the gray resistant or brassy.
Reasoning: the strand test is the warning. Hair that feels mushy and stretches before breaking has lost elasticity. A root-to-end 20 volume application ignores porosity differences and the need to deposit rather than lift. Slower, sectioned, lower-volume work is the correct response to a failed strand test, not a stronger developer.
