Description

Professional blue booster for precise neutralisation of warm tones

Majirel Booster Blue was developed for professionals who leave nothing to chance when it comes to colour. When unwanted warm undertones appear - orange, copper, or excessively warm bases - this blue booster acts with immediate precision.

In the salon, the difference is evident immediately upon mixing. The creamy texture integrates perfectly into Majirel permanent hair colour, maintaining stability, control, and ease of application. The blue acts precisely, neutralising unwanted tones without 'muddying' the colour or compromising the depth of the final shade. The result is cleaner, cooler, and more professional.

Odor Trapping Technology reduces ammonia odour by up to two times during the service, enhancing the experience for both the hairdresser and the client. The formula, enriched with conditioning agents, preserves the hair fibre, leaving hair visibly softer, conditioned, and more manageable - up to three times more softness after colouring.

The vegan formula meets current B2B market demands, combining technical performance, professional awareness, and long-lasting results. When used with Majirel, Booster Blue contributes to rich, uniform coverage and up to 100% grey hair coverage, even in corrective colour services.

Ideal for cool blondes, cool browns, and advanced neutralisation services, Majirel Booster Blue is an essential technical tool for professionals who approach colour with precision, signature style, and consistency.
