L’Oréal Pro Dia Light Gloss Color Hyaluronic Acid Colour 9.31

Color Gloss with Hyaluronic Acid: The Professional 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.

In the basin, the mixture becomes a smooth, easy-to-control cream. During application, you'll feel the difference: it glides on without dripping, envelops the fibre, and "hugs" 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 colour with an acidic pH, created for professional salon technical services: to tone after bleaching, to neutralise unwanted tones, to refresh faded lengths and restore that gloss effect that transforms dull hair into hair with presence. Without ammonia, no lightening, no extra harshness… and with a sensation of a more replenished fibre.

Hyaluronic Acid (hyaluronic complex) acts during the service: it helps restore lost moisture and coat 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, 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.
