- A more shiny and well-groomed look without a lasting, permanent commitment.
Result and durability

- Visible shine and color refinement that typically lasts up to 6 weeks – depending on hair condition and care.
Aftercare and care
- Extend the intensity of your color with color-protecting shampoo and conditioner.
