L’Oréal Pro Dia Light Gloss Color Hyaluronic Acid Hair Colour 7.31
Gloss Colour with Hyaluronic Acid: The Professional Hair Colour that Hydrates While it Transforms
Now renewed - with a new look, the same professional performance you already know… and an even greater focus on shine, hydration, and result precision.
In the backwash, the mixture becomes a smooth, easy-to-control cream. During application, you feel the difference: it glides without dripping, coats the hair fibre, and "embraces" the hair - even when sensitised after bleaching. In 20 minutes, the result appears… mirror shine, cleaner reflections, naturally revived colour.
Dia Light is a tone-on-tone hair colour with an acidic pH, created for professional salon services: toning after bleaching, neutralising unwanted tones, refreshing faded lengths, and restoring that gloss effect that transforms dull hair into hair with presence. Ammonia-free, no lift, no extra aggression… and with a sensation of fuller hair fibre.
Hyaluronic Acid (hyaluronic complex) acts during the service: it helps restore lost moisture and coats the hair fibre with a hydrating layer. The cuticle is more sealed, the touch more disciplined, and the hair gains resistance - ideal when the priority is to preserve the integrity of the cortex and work safely on bleached hair.
For your salon, it means predictability and personalisation: 80 shades + chromatic boosters (Blue, Violet, Red/Orange, Yellow/Orange, Green) to build colour, shine, and neutralisation in detail, with a glossy finish that can last up to 6 weeks.

For professional use
The shade samples are for illustrative purposes only, as they may vary depending on the computer screen used for viewing. Pluricosmética therefore disclaims any responsibility for any colour variations that may arise.
Mix Dia Light with the appropriate developer (Diactivateur 6, 9 or 15 vol.) according to the L'Oréal Professionnel technical protocol and the desired result.
Apply evenly to clean, dry or damp hair, respecting the application areas according to the desired service (roots, lengths or ends).
Processing Time: Leave on for 20 minutes.
Gently emulsify with lukewarm water before rinsing thoroughly. Finish with a post-colour treatment (conditioner or mask) for maximum cuticle sealing and gloss colour fixation.
For chromatic personalisation, add the boosters in the recommended proportion:
Blue Booster – to neutralise orange tones
Violet Booster – to neutralise yellow tones
Red/Orange Boosters – to intensify warm reflections
Yellow & Orange Boosters – to revitalise golden/coppery tones
Green Booster – to neutralise unwanted red tones
Attention: Never combine Blue or Green Booster with copper/red tones that contain Rubilane, Carmilane or DM5.
Hair colourants can cause severe allergic reactions.
Read and follow the instructions.
Carry out a preliminary allergy test 48 hours before applying any colourant. If no irritation occurs, proceed with the application.
Read the leaflet accompanying the product carefully.
This product must not be used on persons under 16 years of age.
For professional use only.
Wear appropriate gloves. If the product comes into contact with eyes, rinse immediately and thoroughly with water.
