Powered by our new ammonia-free technology, L'Oréal Préférence Le Blonding Acidic Toners effectively neutralise unwanted orange and yellow tones for an ultra-blonde that lasts.
After undergoing a bleaching service, the pH level of hair becomes alkaline. This can lead to dull and porous hair. The new Préférence Acidic Toner rebalances the pH level of hair to its natural range preserving hair quality with nutrition and softness. Get up to 4 weeks of pure blonde, in 5 minutes.
