L'Oreal Dialight Colour Chart

L’Oréal Dia Light is an acidic demi-permanent colour designed for refreshing lengths, toning, and adding shine without causing damage. This colour chart helps stylists choose the ideal shade for neutralising, enhancing, or refreshing colour between permanent colour services.

L’Oréal Dia Light is an acidic, demi-permanent colour used to tone, refresh and add shine without lifting the hair. It’s ideal for colour-treated, sensitised or lightened hair.

It’s great for anyone with coloured or sensitised hair who wants to refresh tone, neutralise warmth or add shine, especially after bleaching.

Results typically last up to 6 weeks, depending on the hair condition and proper aftercare.

No. Dia Light is a deposit-only product, so it cannot lighten natural or coloured hair.

Match your level on the colour chart, then choose a tone:

• Ash/Violet – neutralises warmth
  
  

• Beige/Natural – soft, natural results
  
  

• Warm/Copper – enhances warmth

• Yellow: violet
  
  

• Orange: ash/blue
  
  

• Red: green

Typically 20 minutes. For gentle toning, 5–10 minutes may be enough.

It does not fully cover greys but may blend a small amount of soft grey.

No. Its acidic pH is gentle and helps smooth the cuticle for shiny, conditioned results.

Mix 1:1.5, one part colour to 1.5 parts Dia Activateur Developer.

As often as needed. Many use it every 4–6 weeks to maintain tone and shine.
