Attention blondes, do you want to know how you can fight the battle against brass? We have the answer that’ll wash away your worries, and it’s easier than you think.
What causes brass or yellow tones?
Without getting too technical, natural hair colour is produced from tiny pigments found within the middle layer of the hair shaft (for more on hair layers check out our blog A Guide to the Best Hair Treatments.) These pigments become more visible as you chemically lighten them, or even if you’ve been out in the sun for a while.
Whenever you lighten hair – either lifting it a shade lighter, adding highlights or to go blonde, the lifting or bleaching process will stripe the natural colour pigments from the hair before depositing a new colour.
Brassy tones refer to the unwanted warm tones that reveal themselves after lightening hair. These warm brassy tones become a problem when lifting or bleaching expose the underlying natural pigments from the hair.
Dark brown hair will expose underlying red pigments, medium brown hair orange pigments and blonde hair will expose yellow pigments. Generally speaking, these pigments aren’t the desired colour so dye will contain blue or purple pigments to counteract these warm tones. However, blue colour molecules break down more easily, which is why blondes need that little extra special care.
How do you prevent brassy hair?
When red, orange and yellow tones are naturally present in hair and not lifted properly, hair will remain brassy. This is why your salon stylist will follow the lifting or bleaching process with a toner. Toners neutralise colour which helps to remove any remaining warmth.
Maintain the correct colour balance with a purple shampoo and be sure to choose a purple shampoo that contains intense purple pigments to keep colour neutralised whilst restoring colour.
