Client & Diagnosis

Client Profile: Client who specifically wants an ash blonde — not silver, not smoky, but the clean blue-cool classic. Often describes goal as "ash blonde," "cool blonde," or references the classic Nordic ash look. Aged 25–60.
Hair History: Canvas Level 8–9. Classic ash is the most forgiving cool blonde formula in terms of canvas range — clean ash result at Level 8 (deeper, richer ash) or Level 9 (lighter, cooler ash).
Hair Diagnosis: Canvas Level 8–9, tone gold to yellow-gold. If canvas is orange-gold at Level 8, the formula's ash content may be insufficient to neutralize fully — consider adding 3–5g 0/11.
Current Level: Level 8–9
Target Level: Level 8–9 Classic Ash Blonde — clean, blue-cool, directionally ash

The Formula

Formula: 25g 9/1 (Ash Light Blonde) + 5g 0/11 (Blue-Ash Intensifier) + 5g 9/0 (Natural Light Blonde) + 60ml developer
Mixing Ratio: 35g product : 60ml developer (1:1.7 — slightly thinner, appropriate for ash formulas)
Developer: 1.5% / 5 Vol
Timing: 20 minutes. Open air. Check at 18 minutes.
Expected Lift: Zero.

Intelligence Layer

Why It Works: Classic ash is a simple, precise formula. The /1 base (9/1) delivers the ash direction with clarity and depth. The 0/11 intensifier amplifies the blue-ash without adding product mass. The 9/0 natural is the single most important structural component — without it, the ash reads grey and flat. The natural provides the light-reflection quality that makes ash look cool and luminous rather than drab. [S2]
Common Mistakes: (1) Increasing the 0/11 beyond 8g — the formula tips from ash to blue-grey. The intensifier is a precision tool, not a volume product. (2) Omitting the 9/0 natural — the result becomes visually flat and grey rather than ash-cool.
Alternatives: BL-C-001 (Smoky Ash) for more intensity and drama at Level 9. BL-A-003 (Steel Ash) for a deeper, more muted ash.
Maintenance: Refresh every 4–5 weeks. Home: blue-ash shampoo. Clients in hard-water areas should use a chelating treatment monthly.

AI & Case Layer

AI Decision Logic: IF canvas = Level 8–9 AND target = classic ash / clean cool blonde THEN route to BL-A-001. IF canvas = Level 8 AND target cool THEN BL-A-001 is preferable over BL-C-001 (which requires Level 9).
Similar Cases: BL-C-001 (Smoky Ash — more intensity), BL-N-004 (Mushroom — muted, complex)

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.
