L’Oréal Pro Dia Light Gloss Color Hyaluronic Acid Hair Colour 7.23

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 even more focus on shine, hydration, and result precision.

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

Dia Light is an acidic tone-on-tone colour, created for professional 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 sensation of fuller-looking 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 hair feels more disciplined, and becomes more resilient - ideal when the priority is to preserve the integrity of the cortex and work safely on bleached hair.

For your salon, this means predictability and customisation: 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.
