Description
More depth. More intensity – without altering the base tone.
The Majirel Base Contrast Booster is a technical salon tool designed for when colour needs to go further. It doesn't add tone; it amplifies impact. When integrated into the Majirel mix, it directly influences the depth, saturation, and contrast of the colour, especially on dark bases (levels 1 to 4) where the reflection tends to lose visual strength.
In professional practice, its effect is evident from the first contact. The creamy, stable texture allows for a homogeneous mix without waste, ensuring absolute control during application – on roots, lengths, or strategic contrast areas. On hair, the result is immediate: denser dark tones, more defined reflections, a more professional finish... without the need for pre-lightening and without altering the chosen base tone.
Integrated into the Majirel system, it respects the hair fibre while enhancing the chromatic result. Up to 3x more softness after colouring and up to 100% grey hair coverage* make it a reliable ally for demanding technical services. For creative work, it combines precisely with warm Majirel Boosters – copper, magenta, or red – creating intense, controlled, and long-lasting contrasts.
Developed for salons. Optimised for professionals seeking visible, consistent, and replicable results in high-performance permanent colour.
