L'Oréal Professionnel Dia Light Acidic Gloss Color Booster.

L'Oréal Professionnel Dia Light Acidic Gloss Color Booster visibly improves color results while also neutralizing undertones. Its ammonia-free formula is highly suitable for previously colored or weakened hair, as it simultaneously tones and conditions the strands. Its gel-like texture is easy to apply, gliding through the hair to ensure full coverage. As a result, the hair looks shinier and glossier while the previous color becomes more intense and vibrant. Thus, it can be used after a balayage or a lightning session, to tone down undesired shades, or on following color sessions to refresh the tone of the lengths. And all of that without color overload or over-sensitization.
