A professional, demi-permanent tone-on-tone color created to refresh lengths and ends, refine the shade and give a shiny, even finish. L'Oréal Professionnel Dia Light 6 works with an acidic pH level and is ammonia-free, making it particularly suitable for porous or previously colored hair. The color does not build up lightening, but deepens and neutralizes unwanted tones, so your existing hair color looks more uniform, shiny and healthy.
Benefits
- Demi-permanent toning without ammonia – gentle on the hair structure.
- Acidic pH helps smooth the surface and improves reflection and shine.
- Refreshes faded lengths and evens out porosity for a more uniform result.
- Neutralizes unwanted warm or matte tones depending on the shade chosen.
- Stepless, natural fading without sharp growth.
- Ideal for glossing between color treatments or after lightening to refine tone.
Shade 6
Level 6 corresponds to dark blonde/natural depth. This shade is perfect if you want to maintain a dark blonde base, intensify the depth or achieve a more polished and even color expression in the lengths.
Who is it suitable for?
For those with colored or sensitized hair who want to revive color, tone down unwanted tones, or create a glossy, professional finish without lifting your natural color. It can also blend the visibility of individual gray hairs for a more harmonious overall impression.
Result
Hair is left with an even tone, improved reflection and a soft, smooth feel. The color typically lasts up to approximately 6 weeks, depending on hair condition and care routine, and gradually fades with washing.
Note: These are professional colors, which means chemistry, and therefore it is important to have the right information before you get started. Contact your hairdresser, and if you have the necessary knowledge – enjoy a colorful everyday life.
