Advantages

This permanent hair color delivers even, long-wearing color with full coverage of grey hair and visible tone refreshment. The 100 ml format provides a concentrated amount of product suitable for single or touch-up applications.

When it may not be suitable

This product is not intended for users seeking non-permanent or semi-permanent color effects; it is a permanent oxidative dye and requires mixing with a developer. People with very light blonde or pre-lightened hair should consult a professional to assess expected shade results, as underlying hair level affects final color. Do not use if you have a known allergy to hair dye ingredients.
