Why does your salon-fresh blonde & gray hair quickly turn brassy yellow after just a few washes?
Exposure to hard water minerals, daily UV radiation from sunlight, thermal styling heat and natural hair oxidation are the main triggers of unwanted warm yellow and brass undertones. Most regular conditioners lack color-correcting pigment and only moisturize superficially, unable to counteract warm hues. Frequent salon toning touch-ups cost high fees, while cheap purple products either stain hair unevenly or are too mild to neutralize brass effectively.
