What You Need to Know About L'Oreal Dia Richesse

L'Oréal Dia Richesse is an ammonia-free demi-permanent colour that deposits a rich, natural-looking tone with no lift. It blends up to around 70% white hair and is known for warm, luminous, conditioned results that fade softly.

What is Dia Richesse?

Dia Richesse is part of L'Oréal Professionnel's ammonia-free Dia family. Unlike the acidic, translucent finish of Dia Light, Dia Richesse gives a fuller, more opaque deposit – making it a favourite for natural-looking refreshes and softer grey blending.

  • Ammonia-free demi-permanent – low odour, gentle on the hair
  • No lift – deposits tone only, fades with no harsh regrowth line
  • Blends up to ~70% white hair for a natural result
  • Rich, warm, conditioned finish with plenty of shine

What is Dia Richesse used for?

  • Refreshing depth and tone on natural or previously coloured hair
  • Softly blending grey without a solid, flat coverage look
  • Adding warmth and richness between permanent colour services
  • Tone-on-tone work where a fuller deposit than a gloss is wanted

How do you mix Dia Richesse?

Dia Richesse is mixed with L'Oreal Dia Activateur at a low volume (typically 6 or 9 vol). Always follow the current L'Oreal mixing ratio and processing time on pack, and carry out an allergy/skin test before every service. Browse all peroxides & developers at trade prices.

Important: Dia Richesse availability

Dia Richesse has become harder to source in the UK as L'Oreal has consolidated the Dia range. If your usual shade is unavailable, the closest ammonia-free demi alternatives we stock are L'Oreal Dia Color and Dia Light. Full details and shade guidance are in our Dia Richesse availability update.
