Achieve the perfect blonde with L'Oral Paris Prfrence Le Blonding Acidic Toner, designed to neutralize unwanted yellow tones for a pure, icy finish. The L'Oral Paris Preference is powered by our ammonia-free technology. After undergoing a bleaching service, the pH level of hair becomes alkaline. This can lead to dull and porous hair. The new Prfrence Acidic Toner rebalances the pH level of hair to its natural range preserving hair quality with nutrition and softness. This salon-quality toner provides long-lasting results, ensuring your blonde looks fresh and vibrant between colour treatments.
