L’Oréal Pro Dia Light Gloss Color Hyaluronic Acid Hair Colour 9.01

Gloss Colour with Hyaluronic Acid: The Professional Colour that Hydrates While it Transforms

Now renewed - with a new look, the same professional performance you're familiar with… and even more focus on shine, hydration, and precise results.

In the basin, the mixture forms a soft, easy-to-control cream. During application, you'll feel the difference: it glides without dripping, envelops the hair fibre, and "hugs" the hair - even when it's sensitised after bleaching. In 20 minutes, the result appears… mirror-like shine, cleaner reflections, naturally revitalised colour.

Dia Light is an acidic pH tone-on-tone colour, created for professional salon technical services: toning after bleaching, neutralising unwanted tones, refreshing faded lengths, and restoring that gloss effect that transforms dull hair into hair with a noticeable presence. Ammonia-free, no lift, no additional harshness… and with a sensation of fuller-looking fibre.

Hyaluronic Acid (hyaluronic complex) acts during the service: it helps restore lost moisture and coats the fibre with a hydrating layer. The cuticle becomes more sealed, the hair feels more disciplined, and 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.
