DEMO — REQUIRES DINA REVIEW

This formula entry is part of the DCI demo library and has not yet been formally reviewed and approved by Dina Laurent. Do not use for clinical application without independent professional assessment.

Client & Diagnosis

Client Profile: Client who wants a blonde that looks completely natural — no obvious warm or cool direction, simply "their own hair, but better." Often describes goal as "natural," "effortless," "like I was born with it." Works across all skin tones.
Hair History: Canvas Level 8–9. This formula works best from a relatively balanced canvas — Level 8 gold or Level 9 yellow-gold.
Hair Diagnosis: Canvas Level 8–9, tone gold to yellow-gold. At Level 8 gold, the formula reads warmer-neutral. At Level 9 yellow-gold, it reads cooler-neutral. Both are valid expressions.
Current Level: Level 8–9
Target Level: Level 8–9 Natural Neutral Blonde — neither warm nor cool, simply natural

The Formula

Formula: 20g 9/0 (Natural Light Blonde) + 15g 9/1 (Ash Light Blonde) + 5g 9/3 (Gold Light Blonde) + 60ml developer
Mixing Ratio: 40g product : 60ml developer (1:1.5)
Developer: 1.5% / 5 Vol
Timing: 15–20 minutes. Open air.
Expected Lift: Zero.

Intelligence Layer

Why It Works: The /0 (natural) base provides the dimensional, multi-toned quality of naturally grown-out blonde. The /1 (ash) provides partial cool correction of the canvas warmth without completely neutralizing it. The /3 (gold) ensures the result does not drift into the ash family. The ratio (20:15:5) is deliberately imbalanced toward natural, with ash as the second component and gold as the subtle warmth anchor. [S2]
Common Mistakes: (1) Using equal parts natural and ash (20g:20g) — this formula drifts into the ash family on most canvases. The natural must dominate. (2) Omitting the gold component — without the /3, the result on Level 9 canvas reads subtly cool rather than neutral.
Alternatives: BL-N-002 (Beige Blonde) for a warm-leaning neutral. BL-C-001 (Smoky Ash) if the client's true preference is cool. BL-W-002 (Golden Blonde) if the client's true preference is warm.
Maintenance: Refresh every 5–7 weeks. Home: neutral shampoo (neither purple nor gold-enhancing).

AI & Case Layer

AI Decision Logic: IF canvas = Level 8–9 AND target = natural / no obvious direction THEN route to BL-N-001. IF client says "natural" but shows warm inspiration images THEN cross-reference BL-W-002.
Similar Cases: BL-N-002 (Beige — warm-neutral), BL-N-003 (Sandy — earthy neutral)

This is a recommendation. Professional assessment and judgment are required before application. Canvas level, structural condition, and chemical history must be assessed physically at the chair.
