Schwarzkopf Igora Zero Amm 1-0 Natural Black Permanent Color Creme 60ml

Ammonia-free permanent colour

Schwarzkopf Igora Zero Amm 1-0 Natural Black is a permanent cream colour formulated without ammonia for adult users with normal hair. The 60 ml tube delivers full grey coverage and a natural black result while reducing the typical alkaline odour associated with traditional permanent dyes. It suits clients who want a permanent change but prefer a gentler chemical profile.

Replaces ammonia-based permanent colours

This product upgrades from conventional ammonia permanent colours when the priority is a milder scalp experience and less pungent smell during processing. The jump is worth it for colourists and home users who need reliable level-one depth but want to avoid the stronger alkaline lift that can irritate sensitive skin. It is not for buyers who require high-lift bleaching action or fashion shades outside the natural black spectrum.

Simple bowl-and-brush application

Mix the creme with the appropriate developer in a non-metallic bowl, apply with a tint brush and process according to the developer strength chosen. The ammonia-free base reduces fumes, so ventilation remains important but less critical than with standard formulas. Common issues arise when the mixing ratio is guessed instead of measured, or when the developer volume is mismatched to the desired result, leading to uneven coverage or unexpected warmth.
