Setup, Compatibility & Care
L’Oréal Professionnel Majirel BOOSTER is intended for professional use only and must be mixed with a developer in precise ratios as per L’Oréal Professionnel's guidelines. It is compatible with L’Oréal Professionnel's range of developers. Always perform a strand test and patch test 48 hours before full application to check for allergies and predict the final colour outcome. After application, rinse thoroughly and shampoo with a colour-safe shampoo. To maintain colour vibrancy, advise clients to use sulphate-free, colour-protecting shampoos and conditioners and to limit heat styling.
Mixing Ratio:
Consult professional L’Oréal Professionnel guidelines for the specific shade and desired result. Typically involves a 1:1 or 1:1.5 ratio with a Majicrème or Oxydant R developer.
