L’Oréal Pro Dia Light Gloss Color Hyaluronic Acid Colour 6.34

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 an even greater focus on shine, hydration, and precise results.

At the basin, the mixture forms 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 results emerge… mirror-like shine, cleaner reflections, and naturally revived colour.

Dia Light is a tone-on-tone acidic pH hair colour, 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 is 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.
