Loreal Majirel Color Blue Booster - 60ml

L'Oréal Professionnel Majirel Booster Blue is a concentrated permanent colour cream in a 60 ml tube. Colourists mix it into Majirel or Majirouge shades to push the result cooler and to neutralise unwanted warmth.

• Cool reflect control: Boosts ash and cool tones and adds neutralising power to your mix.
• Level stays the same: Shifts the tone of the final colour while keeping the chosen level.
• Adjustable intensity: Add more Booster for a stronger reflect, or less for a softer one.
• Creamy texture: Blends smoothly into the shade and spreads evenly on hair.
• Part of the cool family: Works alongside the Green and Violet Boosters for custom formulas.

How to use: Never apply alone or with developer only. Mix with a Majirel or Majirouge shade first, then add Oxydant Creme. For a full head, use shade, Booster and developer in a 0.25 + 0.75 + 1.5 ratio, for example 45 ml shade, up to 15 ml Booster and 90 ml developer. Contains ammonia. For professional salon use only.
