L’Oréal Pro Dia Light Gloss Color Hyaluronic Acid Hair Color 5

Color Gloss with Hyaluronic Acid: The Professional Colouration that Hydrates Whilst it Transforms

Now refreshed - with a new look, the same professional performance you already trust… and an even greater focus on shine, hydration, and precise results.

At the basin, the mixture develops into a smooth, easy-to-control cream. During application, the difference is noticeable: it glides on without dripping, envelops the hair fibre and "embraces" the hair - even when sensitised after bleaching. In 20 minutes, the result appears… mirror-like shine, cleaner reflections, naturally revived colour.

Dia Light is an acid pH tone-on-tone colouration, created for technical salon services: to tone after bleaching, neutralise unwanted tones, refresh faded lengths and restore that gloss effect that transforms dull hair into hair with presence. Ammonia-free, no lift, no extra aggression… and with a feeling of a more replenished fibre.

The 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 cortex integrity and work safely on bleached hair.

For your salon, this 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.
