Color Gloss with Hyaluronic Acid: The Professional Colour that Hydrates While it Transforms
Now revamped - with a new look, the same professional performance you already know… and an even greater focus on shine, hydration, and result precision.
In the basin, the mixture becomes a smooth, easy-to-control cream. During application, you'll feel the difference: it glides without dripping, wraps the fibre, and "hugs" the hair - even when sensitised after bleaching. In 20 minutes, the result emerges… mirror-like shine, cleaner reflections, naturally revived colour.
Dia Light is a tone-on-tone colour with an acidic pH, created for technical 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-looking fibre.
Hyaluronic Acid (hyaluronic complex) works during the service: it helps restore lost moisture and coats the fibre with a hydrating layer. The cuticle becomes 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 merely indicative, as they may vary depending on the computer screen used for viewing. Pluricosmética therefore declines any responsibility for any colour variations that may occur.
Mix Dia Light with the appropriate developer (Diactivator 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 retention.
For chromatic customisation, 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/copper tones
Green Booster – to neutralise unwanted reddish tones
Attention: Never combine Blue or Green Booster with copper/red shades containing Rubilane, Carmilane or DM5.
Hair colorants can cause severe allergic reactions.
Read and follow the instructions.
Perform a preliminary allergy test 48 hours before applying any colour. 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.
