Leyton House Créme Developer - 1000ml

Leyton House Developer 1000ml features a stabilised, creamy formula designed to deliver consistent lift, smooth blending, and precise tonal accuracy when used with Leyton House permanent and demi‑permanent colour systems; its conditioning base supports hair softness and shine throughout processing, while the controlled viscosity ensures even saturation and predictable results across all levels, making it a reliable choice for professional colourists working with 3%, 6%, 9%, or 12% strengths depending on the desired lift, deposit, or grey coverage. Exclusive Alpine Developers 4.5% (15vol) and 7.5% (25vol) contain a unique blue‑violet pigment that boosts toning performance during lightening, helping to counteract unwanted warm undertones and refine the final result.
