Create a clean, cool blonde tone with L'Oréal Professionnel Dia Light 9.1. This professional tone-on-tone color is designed to refine and refresh blonde hair without lifting the natural tone. The shade 9.1 is a very light ash blonde that effectively dampens warm/yellow reflections and leaves the hair with a mirror-like finish. The acid-based gel-cream is gentle on porous lengths and ideal after lightening, where hair needs color correction with extra shine.
Benefits
- Ammonia-free, acid-based formula – gentle on sensitized and bleached hair.
- Corrects unwanted heat and gives a clear, cool ash reflection.
- Refreshes faded color in lengths and ends without a harsh regrowth edge.
- Gel-cream consistency for smooth, controlled toning and uniform results.
- Leaves hair visibly shinier and with a soft, well-groomed feel.
