L'Oreal Dia Richesse Semi-Permanent Hair Dye No. 420 50ml is the perfect solution for those who want to refresh their hair color with a natural and shiny finish, without compromising its health. This ammonia-free semi-permanent dye is designed to cover up to 70% of gray hair and provide softness and shine, making it suitable for both natural and dyed hair.
Thanks to its alkaline technology, it offers an intense violin brown shade that fades harmoniously over time, avoiding a harsh root effect. Its main advantages include:
- Uniform gray coverage
- Radiant highlights
- Creamy texture that protects the hair fiber during coloring
- Tone-on-tone coloring that respects the integrity of the hair
This results in hair that is softer and more flexible after each use. It is recommended to consult a professional before application.
